🫀 CPT 60270 — Thyroidectomy, Including Substernal Thyroid; Sternal Split or Transthoracic Approach
Quick Reference
wRVU: 22.62 | Global Period: 090 | Assistant Payable: Yes | Bilateral Indicator: 0 Rule: CPT 60270 is the highest-RVU thyroidectomy code in the 60210-60271 range, reflecting the substantially increased surgical complexity and risk associated with thoracic access for substernal thyroid resection via sternal split or transthoracic approach. The bilateral indicator of 0 confirms this is not subject to bilateral payment rules — the thyroid is a single midline organ regardless of intrathoracic extension. Assistant surgery is payable given the extraordinary technical demands of mediastinal dissection, great vessel proximity, and airway management in this procedure. No standalone national LCD governs 60270 specifically; coverage is determined under general Medicare surgical coverage policy and MAC-specific billing and coding articles for endocrine surgery.1,2,3
📋 Clinical Description
CPT 60270 describes the surgical removal of the thyroid gland — including a substernal or intrathoracic component — when the anatomy of the gland’s inferior extension into the mediastinum precludes safe delivery through a standard cervical (collar) incision alone, necessitating either a median sternotomy (sternal split) or a transthoracic approach for adequate exposure and vascular control.1,3 The critical distinction from 60271 (substernal thyroidectomy, cervical approach) is approach-driven: 60270 applies only when a sternotomy or thoracotomy is actually performed and documented, reflecting the significantly greater operative complexity, risk, and resource utilization. Compared to 60240 (total thyroidectomy, standard approach), 60270 captures the added work of thoracic access, mediastinal dissection, and sternal or chest wall closure, which accounts for its higher wRVU valuation of 22.62 versus 60240’s lower valuation.1,2
Substernal goiters are classified as either primary (arising from ectopic mediastinal thyroid tissue with an independent blood supply from mediastinal vessels) or secondary (a cervical goiter with inferior extension into the thoracic inlet and superior mediastinum, blood supply originating from cervical vessels). The vast majority of substernal goiters are secondary, meaning the vascular pedicle remains in the neck and cervical access is sufficient — these cases map to 60271, not 60270. CPT 60270 is reserved for cases where thoracic access is genuinely required, such as true primary mediastinal thyroid masses, cases with mediastinal vascular involvement, posterior mediastinal extension, or failed cervical delivery attempts.3,4
This procedure may be performed in the following clinical contexts:
- Large substernal goiter with significant mediastinal extension below the aortic arch — When the inferior pole of the thyroid or a large nodular goiter descends below the level of the aortic arch or extends into the posterior mediastinum, cervical extraction becomes unsafe due to risk of rupture, vascular injury, or airway compromise; median sternotomy provides the exposure needed for controlled dissection and safe delivery of the gland. Documentation must clearly describe the anatomical extent and the rationale for thoracic access.3,4
- Primary mediastinal (ectopic) thyroid with independent intrathoracic blood supply — True ectopic mediastinal thyroid tissue draws its arterial supply from mediastinal vessels (e.g., internal mammary artery, innominate vessels) rather than the cervical inferior thyroid artery; ligation of these vessels requires direct thoracic exposure via 60270, as cervical access cannot safely control the feeding vasculature.3,4
- Thyroid malignancy with intrathoracic extension or mediastinal nodal involvement — When thyroid carcinoma (C73) extends into the superior mediastinum or when bulky mediastinal lymphadenopathy requires concurrent mediastinal dissection, a sternal split approach provides necessary oncologic exposure; 60270 is appropriate when the substernal component requires thoracic access, though concurrent neck dissection would be separately evaluated for additional code assignment.3
- Recurrent or re-operative substernal thyroidectomy after prior cervical surgery — Post-operative fibrosis and adhesions in the neck following prior thyroidectomy may obliterate the surgical planes needed for cervical delivery of a remaining substernal component; in these cases, a sternal split approach via 60270 may be the safest route for completion resection, particularly when airway involvement is suspected.3,4
- Posterior mediastinal thyroid with spinal or esophageal proximity — Posterior mediastinal thyroid tissue — less common but well-documented — lies posterior to the trachea and esophagus and cannot be approached adequately via a cervical incision; a right thoracotomy approach provides the surgical corridor needed for safe dissection away from the esophagus, aorta, and spinal column.3,4
🔬 Anatomical & Procedural Considerations
| Variant | Mechanism | Key Notes |
|---|---|---|
| Median Sternotomy (Sternal Split) Approach | A midline sternal incision is made from the suprasternal notch inferiorly, the sternum is split with an oscillating saw, and a sternal retractor provides wide mediastinal exposure. The thyroid gland and its substernal component are dissected free from the surrounding mediastinal structures — including the great vessels, innominate vein, superior vena cava, and pericardium — under direct visualization. The recurrent laryngeal nerves require identification both in the neck and within the superior mediastinum, as their course may be distorted by the goiter mass. Sternal closure involves rigid fixation with steel wires, and a mediastinal drain is typically placed. | This is the most common approach for anterior mediastinal substernal thyroid requiring thoracic access. Intraoperative nerve monitoring (IONM, CPT 95940) is strongly recommended given the distorted anatomy and is separately reportable. Cardiothoracic surgery co-surgeon involvement is common, and modifier -62 should be considered when two surgeons of different specialties each perform distinct, integral portions of the procedure. Post-operative chest X-ray, drain management, and sternal wound surveillance are bundled within the 90-day global period.1,2,3 |
| Transthoracic (Lateral Thoracotomy) Approach | A lateral thoracotomy — most commonly a right-sided posterolateral or anterolateral incision through an intercostal space — provides access to the posterior mediastinum for thyroid tissue that cannot be safely approached via a sternotomy. This approach is more commonly used for posterior mediastinal ectopic thyroid masses or when the gland wraps around the trachea and esophagus from a posterior position. Single-lung ventilation with a double-lumen endotracheal tube is typically required, adding anesthetic complexity. The lung is deflected to expose the posterior mediastinal contents, and the thyroid mass is dissected free under direct visualization. | This variant is less commonly performed than the sternotomy approach and represents an even higher surgical complexity. When a thoracic surgeon performs the thoracotomy and an otolaryngologist/endocrine surgeon performs the thyroid dissection simultaneously, co-surgeon billing with modifier -62 is appropriate. The anesthesia complexity (single-lung ventilation, longer operative time) should be considered when evaluating whether modifier -22 is warranted on 60270 for unusual procedural circumstances beyond the standard sternal split case. Chest tube placement and management within the 90-day global period are bundled.1,3,4 |
| Combined Cervical + Thoracic (Hybrid) Approach | The most common operative strategy begins with a standard cervical Kocher incision to mobilize the superior thyroid vessels, identify and preserve the recurrent laryngeal nerves and parathyroid glands from above, and then extend into a sternotomy when the substernal component cannot be safely delivered cervically. This combined approach leverages the cervical access for the familiar superior dissection while the sternal split provides inferior mediastinal exposure for the intrathoracic component. A single operative note should clearly document both phases of dissection and explicitly state why thoracic access was required. | Because both a cervical incision and a sternotomy are part of this approach, coders sometimes incorrectly attempt to bill both 60271 (cervical approach) and 60270 (sternal split) for the same encounter — this is incorrect and constitutes unbundling. CPT 60270 captures the full combined approach when a sternal split or thoracotomy is performed in addition to the cervical dissection; 60271 would only apply when the procedure is completed exclusively through the cervical route without any thoracic access. Always verify from the operative report which approach was actually used to finalize the appropriate code.1,3 |
Clinical Pearl
The single most important documentation element for CPT 60270 billing is the operative report’s explicit statement that a sternal split or transthoracic approach was performed and the clinical rationale for why cervical access alone was insufficient. Payers — including Medicare — may challenge 60270 claims if the operative note does not clearly support medical necessity for thoracic access, particularly since 60271 (cervical approach, lower RVU) exists as an alternative for substernal thyroidectomy achievable without sternotomy. Pre-operative imaging (CT chest, MRI) demonstrating substernal extension below the thoracic inlet or aortic arch level is your primary medical necessity anchor and should be referenced in the operative note. Without this documentation chain, a payer reviewing the claim cannot distinguish 60270 from 60271 and will likely downcode or deny.1,3,4
✅ Procedure Includes
- Cervical and mediastinal dissection of the thyroid gland and its substernal extension — Complete surgical mobilization of the thyroid, including the intrathoracic component, is the primary service of 60270; both the cervical and thoracic phases of dissection are bundled into this single code.1
- Median sternotomy or thoracotomy with associated chest wall entry and closure — The act of splitting the sternum or opening the thoracic cavity (intercostal thoracotomy) and the subsequent rigid sternal wire fixation or chest wall closure are integral to 60270 and are not separately reportable by the operating surgeon.1
- Identification and preservation of recurrent laryngeal nerves — Bilateral RLN dissection and preservation, including within the distorted mediastinal anatomy, is a required component of the procedure and is not separately billable.1
- Identification and preservation or auto-transplantation of parathyroid glands — Meticulous parathyroid gland management is integral to the surgical package; incidental parathyroid auto-transplantation is not separately reportable.1
- Ligation and division of thyroid and mediastinal vascular supply — Includes superior and inferior thyroid vessels as well as any mediastinal feeding vessels (internal mammary, innominate branches) encountered during thoracic dissection.1
- Mediastinal and/or pleural drain placement — When a closed suction drain or chest tube is placed as part of the 60270 operative session, placement and management during the global period are bundled into the surgical package.1
- Standard wound closure (cervical and sternal/thoracic) — Layered closure of both the cervical incision and the sternotomy or thoracotomy wound, including sternal wire placement, is included in the global package.1
- Post-operative visits within 90-day global period — All E/M services by the same surgeon related to normal recovery from 60270 are bundled from the day of surgery through post-operative day 90.1,2
❌ Excludes / Do Not Report Together
| Code | Description | Relationship |
|---|---|---|
| 60271 | Thyroidectomy, including substernal thyroid; cervical approach | 60271 and 60270 are mutually exclusive — they describe the same clinical scenario (substernal thyroidectomy) but via different approaches; 60270 is used when a sternal split or thoracotomy is performed, while 60271 is used when the substernal component is successfully removed through a cervical incision without thoracic access. Never bill both codes for the same operative session regardless of the surgical technique used.1 |
| 60240 | Thyroidectomy, total or complete | 60240 describes a standard total thyroidectomy without substernal extension or thoracic access; do not substitute 60240 for 60270 when substernal extension requiring thoracic approach is documented, as this would undercode the service and misrepresent the operative complexity. Conversely, do not separately bill 60240 alongside 60270 as the thyroidectomy work is entirely captured within 60270.1 |
| 60522 | Thymectomy, partial or total; sternal split or transthoracic approach, without radical mediastinal dissection | When a thymectomy is incidentally performed in the same sternal split operative session as 60270, the thymectomy may be separately reportable with modifier -51 if it is a distinct, independently medically necessary procedure supported by separate documentation — coders must review NCCI edits, verify that separate medical necessity is documented for the thymectomy, and confirm the operative note distinguishes the thyroid resection from the thymic resection as anatomically and procedurally independent work.1,5 |
| 60500 | Parathyroidectomy or exploration of parathyroid glands | Parathyroid work incidental to thyroidectomy (preservation, auto-transplantation) is bundled into 60270 and is not separately reportable; 60500 is only billable when a distinct, independent parathyroid pathology with separate documented medical necessity is addressed, per CPT Assistant December 2012 guidance.1 |
Bundling Alert
CPT 60270 carries a 90-day global period covering all related post-operative care from the surgery date through post-op day 90. The most significant audit risk for 60270 is the improper dual-billing of both 60270 and 60271 for the same operative session, or separately reporting the sternotomy/thoracotomy as a standalone thoracic surgery code — the chest access is integral to 60270’s descriptor and is non-separately reportable by the operating surgical team. Additionally, co-surgeon billing (modifier -62) between the head-and-neck surgeon and cardiothoracic surgeon is common and clinically appropriate for this procedure, but each co-surgeon must submit a separate operative note documenting their distinct portion of the work, or CMS will treat one surgeon’s claim as a duplicate. NCCI edits between 60270 and concurrent neck dissection codes (38720, 38724) require careful review when both thyroid resection and neck lymphadenectomy are performed in the same session — modifier -59 with anatomical specificity in the operative report is required when legitimately unbundling.1,2,5

💰 RVU & Reimbursement Profile
| Component | Value |
|---|---|
| Work RVU | 22.62 |
| Global Period | 090 |
| Bilateral Indicator | 0 — Not subject to bilateral reduction; thyroid is a single midline organ |
| Assistant Surgeon | Payable — Modifier -80 or -AS applicable |
| Co-Surgeon | Payable — Modifier -62 applicable; common when otolaryngologist and cardiothoracic surgeon jointly perform the procedure |
| Team Surgery | Payable — Modifier -66 applicable for cases requiring simultaneous multi-surgeon team |
| PC/TC Split | 0 — No professional/technical component split; surgical procedure only |
| Modifier -51 Exempt | No — Subject to multiple procedure reduction rules when billed with secondary procedures |
| Anesthesia | General anesthesia; single-lung ventilation (double-lumen ETT) required for transthoracic approach; anesthesia provider bills separately |
Bilateral Billing Rules
CPT 60270 has a bilateral indicator of 0 — the thyroid is a single midline structure and the procedure is not subject to bilateral payment adjustments regardless of bilateral lobe involvement or bilateral RLN dissection. Modifier -50 is never appropriate for 60270. The higher wRVU of 22.62 (compared to 60240 at approximately 14.60 and 60271 at approximately 17.18) reflects the additional complexity of thoracic access rather than any bilateral component; do not attempt to justify a bilateral modifier as a substitute for correct code selection.1,2
🏷️ Modifier Reference
| Modifier | Name | When to Apply |
|---|---|---|
| -22 | Increased Procedural Services | Apply when the procedure is substantially more complex than a typical 60270 — e.g., a massive posterior mediastinal thyroid adhered to the aorta, esophagus, and spine requiring extraordinary dissection time and technique; documentation must clearly describe the unusual complexity, increased operative time, and specific anatomical challenges beyond standard substernal thyroidectomy via sternal split.1 |
| -51 | Multiple Procedures | Append to secondary procedures billed in the same operative session as 60270 (e.g., 60521 for a separately medically necessary thymectomy performed concurrently); 60270 as the primary and typically highest-RVU code would be listed first without -51, with -51 on the secondary code subject to standard multiple procedure reduction rules.1 |
| -59 | Distinct Procedural Service | Use on a secondary procedure code when it represents work anatomically or procedurally distinct from what is included in 60270 — e.g., a separately identifiable neck lymph node dissection (38724) for documented concurrent malignant adenopathy; the operative note must clearly support separate anatomical sites and distinct procedural work.1,5 |
| -62 | Two Surgeons | Apply when an otolaryngologist/endocrine surgeon and a cardiothoracic surgeon each perform distinct, integral portions of 60270 — e.g., one surgeon manages the cervical and thyroid dissection while the other performs and closes the sternotomy; both surgeons bill 60270-62 and each must submit a separate operative note documenting their distinct contribution.1 |
| -66 | Surgical Team | Used when the complexity of the case requires a surgical team approach with multiple simultaneous surgeons — applicable for particularly complex cases with great vessel involvement, mediastinal tumor invasion, or concurrent cardiac/thoracic pathology addressed in the same operative session.1 |
| -80 | Assistant Surgeon | Payable for 60270; the assistant surgeon (MD) bills 60270-80; the mediastinal approach and RLN/parathyroid preservation complexity well supports medical necessity of a qualified assistant surgeon, particularly when co-surgeon arrangement is not used.1,2 |
| -AS | PA/NP/CNS as Assistant | When a non-physician practitioner serves as assistant-at-surgery, bill 60270-AS; reimbursement is typically 85% of the 16% assistant surgeon allowance.2 |
| -24 | Unrelated E/M During Global | Append to E/M codes billed by the same surgeon during the 90-day global period when the visit is for a completely unrelated diagnosis; documentation must clearly support a condition distinct from substernal thyroidectomy recovery.1 |
| -25 | Significant Separate E/M | Apply in rare scenarios where a separately identifiable E/M is performed on the same day as 60270 for a new, distinct problem unrelated to the planned surgical encounter; thorough documentation required.1 |
| -52 | Reduced Services | Apply in rare scenarios where a planned sternal split approach was modified intraoperatively to a less extensive approach than anticipated — but note that if the sternal split or thoracotomy was never actually performed, the correct code would be 60271, not 60270-52; use -52 only when the thoracic access was initiated and partially performed under exceptional circumstances.1 |
| -53 | Discontinued Procedure | Use if the procedure was started but terminated before completion due to a life-threatening intraoperative event (e.g., cardiac arrest, uncontrolled hemorrhage); attach to 60270 with explicit operative note documentation of why the procedure was stopped.1 |
| -58 | Staged Procedure | Apply when a subsequent procedure during the 90-day global period was prospectively planned at the time of 60270 — e.g., planned post-operative radioiodine ablation workup visit or a planned second-stage neck dissection; staging must be prospectively documented in the original operative note.1 |
| -78 | Return to OR (Related) | Use when the patient requires an unplanned return to the operating room during the global period for a complication directly related to 60270 — e.g., sternal wound dehiscence requiring surgical debridement, post-operative mediastinal hemorrhage; only the intraoperative portion of the work is separately billable.1 |
| -79 | Unrelated Return to OR | Apply when the patient returns to the OR during the 90-day global period for a procedure entirely unrelated to the thyroidectomy; a new global period begins for the unrelated procedure.1 |
🩺 Common ICD-10-CM Pairings
Primary Diagnosis Group
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| E04.0 | Nontoxic diffuse goiter | No | The most common benign indication; diffuse, non-nodular goiter with substernal extension causing compressive symptoms (dysphagia, dyspnea, stridor, SVC syndrome) is the classic 60270 scenario; document compressive symptoms as additional diagnoses to strengthen medical necessity.6 |
| E04.2 | Nontoxic multinodular goiter | No | Multinodular goiter is the most prevalent thyroid disorder requiring substernal thyroidectomy; ICD-10-CM 2026 E04.2 is the specific, billable code — confirm absence of toxic function before assigning the “nontoxic” designation, and code compressive symptoms (dysphagia R13.10, stridor R06.1) additionally when documented.6 |
| C73 | Malignant neoplasm of thyroid gland | Yes — HCC 12 | When thyroid malignancy extends into the mediastinum and requires thoracic access, C73 is the primary diagnosis; concurrent C77.0 (secondary malignant neoplasm of lymph nodes of head, face and neck) should be added when mediastinal or cervical nodal involvement is confirmed.6 |
| E05.20 | Thyrotoxicosis with toxic multinodular goiter without thyrotoxic crisis or storm | No | Toxic multinodular goiter (Plummer disease) with substernal extension causing compressive symptoms and refractory hyperthyroidism is a valid 60270 indication; confirm absence of thyrotoxic crisis (E05.21) before assigning E05.20, and code the substernal goiter separately when documented as a distinct condition contributing to the surgical decision.6 |
| E05.21 | Thyrotoxicosis with toxic multinodular goiter with thyrotoxic crisis or storm | Yes — HCC 23 | Report when thyrotoxic storm is documented perioperatively; this is an HCC-relevant, high-severity diagnosis that significantly impacts DRG assignment and risk adjustment — CDI query is warranted whenever post-operative thyrotoxic crisis signs are present without explicit physician documentation.6 |
Secondary Group
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| E89.0 | Postprocedural hypothyroidism | No | Expected sequela of total thyroidectomy for substernal goiter; code at post-operative encounters when the patient begins thyroid hormone replacement; supports continued medical management documentation.6 |
| E89.2 | Postprocedural hypoparathyroidism | No | Parathyroid gland injury is a significant risk during substernal thyroidectomy given the distorted mediastinal anatomy; report when hypocalcemia is documented as attributable to parathyroid devascularization post-60270; relevant to DRG severity tier in the inpatient setting.6 |
| J38.01 | Paralysis of vocal cords and larynx, unilateral | No | Recurrent laryngeal nerve injury risk is elevated in 60270 due to mediastinal anatomy distortion from the substernal goiter; code only when confirmed by post-operative laryngoscopy documentation from the treating physician.6 |
| R06.1 | Stridor | No | A key compressive symptom that supports medical necessity for surgical intervention; when documented pre-operatively as a symptom driving the surgical decision for 60270, stridor may be coded as an additional diagnosis in the inpatient setting.6 |
Etiology / Complication
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| E83.51 | Hypocalcemia | No | Sequence after E89.2 when both hypoparathyroidism and its hypocalcemia manifestation are documented post-operatively; both codes may be required to fully represent the complication cascade per ICD-10-CM coding conventions.6 |
| J98.11 | Atelectasis | No | A documented pulmonary complication relevant to the thoracic approach; post-operative atelectasis following sternal split or thoracotomy in the setting of 60270 should be coded when confirmed radiologically or clinically and treated — relevant to CC status for DRG assignment.6 |
Coding Specificity Reminder
E04.0 and E04.2 are frequently the primary diagnoses for 60270 in benign cases, but coders must confirm the thyroid function status (toxic vs. nontoxic) before assigning nontoxic goiter codes — misassigning a nontoxic code when thyroid function studies demonstrate hyperthyroidism is a common and auditable error. Always code compressive symptoms (dysphagia, stridor, SVC syndrome) as additional diagnoses when documented, as these directly support the surgical medical necessity for the substernal approach. For malignant indications, C73 is the only ICD-10-CM billable code for primary thyroid malignancy — there are no histology-specific expansions of C73 in ICD-10-CM, and the code itself is the full-specificity, billable endpoint.6
🏥 MS-DRG Considerations
CPT 60270 maps to MS-DRG 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC), MS-DRG 629 (with CC), or MS-DRG 630 (without CC/MCC) under FY2026 IPPS v43.0. Due to the thoracic nature of this procedure, post-operative complications such as atelectasis (J98.11), post-procedural hypoparathyroidism (E89.2), hypocalcemia (E83.51), vocal cord paralysis (J38.01), and mediastinal hemorrhage carry high potential as CC or MCC designations that shift DRG assignment to a higher-weighted tier. When the indication is thyroid malignancy (C73) with substernal mediastinal extension, a thoracic surgeon’s co-operative note and the presence of concurrent lymph node metastasis (C77.0) further affects DRG severity. CDI teams should proactively query for documentation of all post-operative complications, comorbidities, and the specific indication (benign vs. malignant) to ensure accurate DRG assignment and appropriate reimbursement for the facility’s resource utilization on what is inherently a complex inpatient surgical case.2,7
📋 LCD / Coverage Information
LCD Status for CPT 60270
There is no standalone national Local Coverage Determination (LCD) or National Coverage Determination (NCD) governing CPT 60270 specifically as of FY2026. Thyroidectomy procedures, including substernal thyroidectomy, are covered under general Medicare surgical coverage policy without a dedicated LCD at the national level. Coverage for CPT 60270 is determined by: (1) general Medicare reasonable and necessary standards under §1862(a)(1)(A) of the Social Security Act, (2) MAC-specific Billing and Coding Articles for endocrine surgery (check your jurisdictional MAC — e.g., CGS, Noridian, Novitas, WPS, FCSO — via the CMS Medicare Coverage Database at MCD.cms.gov), and (3) clinical documentation supporting medical necessity for thoracic access specifically, since the existence of 60271 (cervical approach) as a lower-coded alternative creates an inherent payer scrutiny point for claims submitted under 60270. Pre-operative CT or MRI imaging demonstrating substernal thyroid extension below the thoracic inlet, coupled with an operative note explicitly justifying why a cervical-only approach was insufficient, constitutes the strongest medical necessity documentation package. Some commercial payers and regional MACs may have Billing and Coding Articles that list specific ICD-10-CM codes required to support 60270 claims — always verify current articles for your jurisdiction before billing.3,5,8
🔧 ICD-10-PCS Equivalents
| PCS Code | Full Description | Modality |
|---|---|---|
| 0GTK0ZZ | Resection of Thyroid Gland, Open Approach | The primary PCS code capturing the thyroid gland resection component of CPT 60270; the open approach (character 0) correctly reflects the direct surgical access via sternal split or thoracotomy. |
| 0WC60ZZ | Control Bleeding in Mediastinum, Open Approach | May be used as an additional PCS code when intraoperative mediastinal hemorrhage control is separately documented as a distinct procedural step during the thoracic dissection phase. |
| 07T50ZZ | Resection of Right Neck Lymphatic, Open Approach | Applicable when concurrent limited right-sided cervical neck dissection is documented in addition to the substernal thyroidectomy; ICD-10-PCS requires separate body-part coding for lymphatic resection. |
| 07T60ZZ | Resection of Left Neck Lymphatic, Open Approach | Applicable when concurrent limited left-sided cervical neck dissection is performed alongside 60270; both 07T50ZZ and 07T60ZZ may be assigned when bilateral central neck dissection is documented. |
PCS Character Analysis (Primary Code: 0GTK0ZZ)
| Position | Character | Value | Definition |
|---|---|---|---|
| 1 | Section | 0 | Medical and Surgical — the root section for all operative procedural coding in ICD-10-PCS. |
| 2 | Body System | G | Endocrine System — encompasses thyroid, parathyroid, adrenal glands, and related endocrine structures. |
| 3 | Root Operation | T | Resection — cutting out or off, without replacement, ALL of a body part; total thyroidectomy maps to Resection, not Excision (B), because the entire gland is removed. |
| 4 | Body Part | K | Thyroid Gland — the single PCS body part value for the complete thyroid gland; no laterality character exists in ICD-10-PCS for the thyroid since it is a single unified organ. |
| 5 | Approach | 0 | Open — the standard approach for CPT 60270; direct surgical access through a cervical incision plus sternal split or thoracotomy, meeting the ICD-10-PCS definition of open approach (cutting through the skin/mucous membrane and any other body layers). |
| 6 | Device | Z | No Device — no implantable device is placed within the thyroid operative site as part of this resection procedure. |
| 7 | Qualifier | Z | No Qualifier — no additional specification applies; the substernal approach is not a separate PCS qualifier in the Endocrine System body system table. |
Root Operation Comparison
- Resection (T) vs. Excision (B): Use Resection (0GTK0ZZ) for total thyroidectomy, which removes the entire gland — this is the correct root operation for CPT 60270 when the entire thyroid including substernal extension is removed. Use Excision (0GTB0ZZ — Body Part K, Thyroid Gland) only for partial thyroid resections; the key PCS principle is that Resection applies to ALL of a body part while Excision applies to a portion only.
- Mediastinal Dissection Coding in PCS: Unlike CPT, which bundles the thoracic access and mediastinal work into the 60270 descriptor, ICD-10-PCS may require separate procedure codes for distinct body part work performed in the mediastinal compartment (e.g., control of mediastinal bleeding, division of mediastinal adhesions) — each distinct root operation on a distinct body part requires a separate PCS code, reflecting the fundamental ICD-10-PCS philosophy of discrete body-part and root-operation specificity.7
- Approach Distinction: All clinically performed variants of 60270 — sternal split, thoracotomy, or combined cervical-sternal — use Open approach (character 0) in ICD-10-PCS because they all involve cutting through skin and body wall layers for direct visualization and instrument passage; there is no separate PCS approach character for “transthoracic” versus “sternal split” within the Endocrine System body system table.7
📝 Coding Examples
Example 1
Clinical Scenario: A 71-year-old female with a 15-year history of multinodular goiter presents with progressive dysphagia and exertional stridor. CT chest with contrast demonstrates a large, predominantly right-sided multinodular goiter with inferior extension 4 cm below the level of the aortic arch into the anterior superior mediastinum, displacing the trachea to the left. PFTs confirm fixed upper airway obstruction. Pre-operative laryngoscopy documents normal bilateral vocal cord mobility. An otolaryngologist (head and neck surgeon) and cardiothoracic surgeon jointly perform a combined Kocher incision with extension to median sternotomy. The right lobe and its substernal extension are delivered under direct mediastinal visualization. Total thyroidectomy is completed. Both surgeons each perform distinct, integral portions of the procedure and each submit separate operative notes.
| Field | Code | Rationale |
|---|---|---|
| CPT (Both Surgeons) | 60270-62 | Total thyroidectomy including substernal thyroid via sternal split; modifier -62 applied for co-surgeon arrangement — otolaryngologist performs thyroid dissection and cervical component, cardiothoracic surgeon performs sternotomy, retraction, and mediastinal exposure; both surgeons bill 60270-62.1,2 |
| PDx | E04.2 | Nontoxic multinodular goiter — the primary indication for surgery; confirmed nontoxic (euthyroid on pre-operative labs), with documented multinodularity on imaging.6 |
| ADx | R06.1 | Stridor — documented compressive symptom supporting medical necessity for surgical intervention and specifically for the substernal/thoracic approach.6 |
Note
Pre-operative CT imaging documenting substernal extension below the aortic arch is the critical medical necessity anchor for 60270 over 60271; both the referring physician’s documentation and the surgeon’s operative note should reference the imaging findings explicitly. The co-surgeon arrangement requires that each surgeon’s operative note describe their specific contribution to be payable under modifier -62.1,2
Example 2
Clinical Scenario: A 58-year-old male with known papillary thyroid carcinoma, status post right thyroid lobectomy performed 18 months ago, presents for completion thyroidectomy. Post-operative imaging reveals a recurrent left-sided thyroid remnant with a 3 cm mass extending posterior to the trachea and into the left posterior mediastinum. A right posterolateral thoracotomy approach is selected by the surgical team (otolaryngologist and thoracic surgeon) to access the posterior mediastinal component safely, given the posterior position and extensive adhesions from the prior cervical surgery. The left thyroid lobe and posterior mediastinal extension are resected via a combined cervical and transthoracic approach. Final pathology confirms residual papillary thyroid carcinoma.
| Field | Code | Rationale |
|---|---|---|
| CPT | 60271-62 | Thyroidectomy including substernal thyroid, transthoracic approach; modifier -62 for co-surgeon; transthoracic (thoracotomy) is explicitly documented in the operative note, confirming 60270 over 60271. Note: 60260 (completion thyroidectomy) is NOT reported separately — 60270 captures the full procedural work including the completion element when thoracic access is required.1 |
| PDx | C73 | Malignant neoplasm of thyroid gland — residual/recurrent papillary thyroid carcinoma confirmed on pre-operative imaging and post-operative pathology.6 |
| ADx | Z85.850 | Personal history of malignant neoplasm of thyroid — prior right lobectomy for thyroid malignancy provides clinical context for the completion procedure; code as secondary diagnosis.6 |
Warning
A common error in completion thyroidectomy scenarios is dual-billing 60260 (completion thyroidectomy) alongside 60270 for the same operative session — this is an NCCI bundling violation. CPT 60270 fully captures the thyroidectomy work including any completion element when the substernal approach via sternotomy or thoracotomy drives the code selection. The transthoracic approach must be clearly documented in the operative note or payers will downcode to 60260 or 60271.1,5
Example 3
Clinical Scenario: A 44-year-old female with Graves disease and a large toxic multinodular goiter is brought to the OR after failing radioiodine therapy and experiencing ongoing symptoms including palpitations, weight loss, and progressive dysphagia. Neck and chest CT demonstrates a 9 cm goiter with anterior mediastinal extension to the level of the main pulmonary artery. Surgery is performed via Kocher incision with median sternotomy extension. Total thyroidectomy is completed. Post-operatively, the patient develops symptomatic hypocalcemia with documented hypoparathyroidism on day 2, and is discharged on day 5 with oral calcium and calcitriol. She returns to the same surgeon at 6 weeks for a separate evaluation of new-onset atrial fibrillation unrelated to her thyroid condition.
| Field | Code | Rationale |
|---|---|---|
| CPT (Surgery) | 60271 | Thyroidectomy, including substernal thyroid; sternal split approach — single surgeon performing both cervical and mediastinal dissection without a co-surgeon arrangement; no modifier -62 needed.1 |
| CPT (Post-op E/M) | 99213-24 | 6-week visit for new-onset atrial fibrillation — modifier -24 (unrelated E/M during global period) required; documentation must clearly establish atrial fibrillation as a new condition unrelated to the thyroidectomy global period; ideally note the thyroid condition is being monitored but the visit’s primary focus is the cardiac problem.1,2 |
| PDx | E05.20 | Thyrotoxicosis with toxic multinodular goiter without thyrotoxic crisis — Graves with toxic multinodular features confirmed; absence of crisis/storm documented.6 |
| ADx | E89.2 | Postprocedural hypoparathyroidism — documented day 2 post-operatively; affects DRG assignment as a complication and supports the extended inpatient stay.6 |
| ADx | E83.51 | Hypocalcemia — sequenced after E89.2 as the manifesting condition per ICD-10-CM conventions.6 |
Global period reminder
The 90-day global period for CPT 60270 begins on the day of surgery (day 0 per CMS global period counting rules for 090 codes). The post-operative hypocalcemia and hypoparathyroidism are complications related to 60270 and are clinically managed during the global period — any related office visits by the same surgeon for these complications are bundled. The atrial fibrillation evaluation is separately billable only because it is a clearly unrelated new condition, documented as such, with modifier -24 appended. Failure to apply modifier -24 will result in automatic denial of the E/M claim during the global period.1,2
⚠️ Common Coding Pitfalls
- Pitfall 1 — Assigning 60270 when only a cervical approach was performed: The most frequent and consequential coding error is applying 60270 when the operative note describes successful substernal thyroidectomy completed entirely through the cervical incision without any sternotomy or thoracotomy — that scenario maps to 60271, not 60270. The sternal split or transthoracic access is the defining criterion for 60270; always confirm from the operative report that the chest was actually opened before assigning this code.1,3
- Pitfall 2 — Dual-billing 60270 and 60271 for the same session: Some coders attempt to bill both codes when a combined cervical-sternal approach is used, reasoning that the cervical work maps to 60271 and the thoracic work to 60270 — this is incorrect and constitutes unbundling. CPT 60270 encompasses the total procedure including both its cervical and thoracic components; when a sternal split or thoracotomy is performed, 60270 is the sole appropriate thyroidectomy code regardless of the extent of cervical work also performed.1
- Pitfall 3 — Failure to use modifier -62 when two surgeons jointly perform 60270: When a head-and-neck surgeon and a cardiothoracic surgeon each perform distinct integral portions of the 60270 procedure simultaneously or in sequence, co-surgeon billing with modifier -62 is the correct arrangement — failing to use modifier -62 means one surgeon’s claim will be denied as a duplicate when both submit 60270. Conversely, do not use modifier -62 when only one surgeon performs the entire procedure with a second surgeon assisting; in that case, the assistant bills modifier -80 or -AS.1,2
- Pitfall 4 — Separately billing the sternotomy or thoracotomy: Some coders erroneously add a standalone thoracic surgery code for the sternotomy (e.g., from the thoracic surgery CPT range) in addition to 60270, reasoning that the chest access is separately reportable work. The sternal split or transthoracic approach is integral to the 60270 descriptor — it cannot be separately billed by any member of the operative team as an additional procedure for the same operative session.1,5
- Pitfall 5 — Under-coding secondary diagnoses affecting DRG/severity: In the inpatient setting, post-operative complications of 60270 (E89.2 hypoparathyroidism, E83.51 hypocalcemia, J38.01 vocal cord paralysis, J98.11 atelectasis, mediastinal hemorrhage) are frequently under-documented and under-coded, resulting in lost DRG weight and inadequate severity-of-illness capture. Given the thoracic complexity of this procedure, inpatient cases for 60270 have significant potential for CC/MCC-level complications that CDI should proactively query and coders should diligently capture from all physician documentation sources.2,7
- Pitfall 6 — Missing the medical necessity documentation for 60270 vs. 60271: Because 60270 exists as the lower-valued substernal thyroidectomy cervical-approach alternative, payers may scrutinize 60270 claims and require explicit documentation of why thoracic access was necessary. Coders should verify that the claim is supported by pre-operative imaging documenting the extent of substernal extension (below the thoracic inlet, aortic arch level, posterior mediastinum), the surgeon’s operative note rationale for thoracic access, and the explicit surgical procedure confirming sternotomy or thoracotomy was performed — without this documentation chain, payers may downcode the claim to 60271 on post-payment audit.1,3,4,5
