🦋 CPT 60200 — Excision of Cyst, Adenoma or Other Benign or Malignant Tumor of Thyroid, or Transection of Isthmus
Quick Reference
wRVU: 9.86 | Global Period: 090 | Assistant Payable: Yes | Bilateral Indicator: 0 Rule: CPT 60200 carries a full 90-day major surgical global period, bundling all routine pre-operative evaluation the day before surgery and all related post-operative care for 90 days into the single reported code.¹ Its bilateral indicator of “0” reflects the fact that the thyroid is a single midline gland, so the 150% bilateral payment adjustment rule that applies to paired-organ codes does not apply here even when both lobes are involved. Because it does not require formal lobectomy, this code is reserved for discrete cyst or adenoma removal or isolated isthmus transection rather than for the more extensive lobectomy family (60210-60225).
📋 Clinical Description
CPT 60200 describes… an open cervical approach procedure in which the surgeon excises a discrete cyst or adenoma from the thyroid gland, or alternatively divides (transects) the isthmus connecting the two thyroid lobes, without performing a formal partial or total lobectomy. This code occupies a narrower surgical scope than its sibling codes 60210 (partial thyroid lobectomy) and 60220 (total thyroid lobectomy), both of which involve removal of an entire anatomic lobe rather than a focal lesion or isolated isthmus segment. Because the procedure targets a specific mass or the isthmus alone, it is typically reserved for smaller, well-circumscribed lesions or for isthmusectomy performed as an isolated procedure, such as to gain surgical access for an unrelated tracheal procedure.
Clinically, surgeons select 60200 when preoperative imaging and biopsy findings support a discrete, resectable lesion rather than diffuse multinodular disease requiring lobar removal. The isthmus-transection application of this code is distinct from the more extensive 60280 thyroglossal duct cyst excision, since 60200’s isthmus work addresses the thyroid gland itself rather than a persistent embryologic duct remnant. Documentation must clearly describe the discrete nature of the lesion removed or the isolated isthmus transection performed, since payers frequently question whether a more extensive lobectomy code should have been reported instead.
This procedure may be performed in the following clinical contexts:
- Solitary benign thyroid nodule — excision of a well-defined cyst or adenoma identified on ultrasound and confirmed benign or indeterminate on fine-needle aspiration biopsy.
- Symptomatic thyroid cyst — removal of a cyst causing compressive symptoms such as dysphagia or a visible cosmetic deformity, without diffuse gland involvement.
- Isolated isthmusectomy for surgical access — transection of the isthmus performed as part of gaining exposure for an unrelated procedure, such as tracheostomy or cervical spine surgery.
- Isthmus-confined malignancy — excision of a small well-differentiated thyroid carcinoma isolated entirely to the isthmus in a carefully selected patient, avoiding the morbidity of a full lobectomy.
- Diagnostic excisional biopsy — removal of an indeterminate nodule when core or fine-needle biopsy results were inconclusive and histologic diagnosis requires excision of the entire lesion.
🔬 Anatomical & Procedural Considerations
| Variant | Mechanism | Key Notes |
|---|---|---|
| Cyst/adenoma excision | The surgeon makes a low transverse cervical incision, dissects through the strap muscles to expose the thyroid capsule, and carefully shells out the discrete cyst or adenoma while preserving surrounding normal thyroid parenchyma and the recurrent laryngeal nerve. | This variant preserves the maximum amount of functioning thyroid tissue and is favored when the lesion is well-encapsulated and separable from adjacent gland, reducing the risk of post-operative hypothyroidism compared to lobectomy. |
| Isthmus transection | The isthmus is isolated between the two lobes, ligated or cauterized at its margins, and divided, effectively separating the right and left thyroid lobes without removing lobar tissue. | This approach is often performed to improve surgical exposure for an adjacent procedure or to address isthmus-confined pathology, and carries a lower complication profile than lobectomy since the recurrent laryngeal nerve dissection required for lobectomy is typically avoided. |
| Combined cyst excision with isthmus division | Some cases require both excision of a lesion and division of the isthmus in the same operative session when the pathology spans or approaches the isthmus. | Only a single unit of 60200 is reported regardless of whether both the cyst excision and isthmus transection are performed together, since the code descriptor already bundles these as alternative or combined elements of the same service. |
Clinical Pearl
Auditors frequently scrutinize 60200 claims to confirm the operative note describes a truly discrete excision rather than a de facto partial lobectomy that should have been billed as 60210.² Look for explicit documentation of preserved surrounding thyroid parenchyma and an intact capsule margin around the excised specimen to substantiate that a formal lobectomy was not performed. When in doubt, query the surgeon on the extent of gland tissue removed before finalizing code selection.
✅ Procedure Includes
- Cervical incision and dissection through the platysma and strap muscles to expose the thyroid gland.
- Identification and preservation of the recurrent laryngeal nerve and parathyroid glands during dissection around the target lesion.
- Excision of the discrete cyst or adenoma, or transection and ligation of the isthmus, as clinically indicated.
- Hemostasis of the surgical bed using electrocautery or suture ligation.
- Closure of the strap muscles, platysma, and skin in layers, with or without placement of a surgical drain.
- Routine post-operative wound checks and suture or staple removal within the 90-day global period.
❌ Excludes / Do Not Report Together
| Code | Description | Relationship |
|---|---|---|
| 60210 | Partial thyroid lobectomy, unilateral; with or without isthmusectomy | Represents a more extensive procedure removing an entire lobe rather than a discrete lesion; 60200 and 60210 are mutually exclusive for the same operative session since one code should capture the full extent of gland tissue removed. |
| 60220 | Total thyroid lobectomy, unilateral; with or without isthmusectomy | An even more extensive unilateral lobectomy code; reporting both 60200 and 60220 together for the same lobe would misrepresent the actual extent of surgery performed and is not separately payable. |
| 60280 | Excision of thyroglossal duct cyst or sinus | Targets an embryologic duct remnant rather than thyroid gland tissue itself; these are anatomically distinct structures and may be reported together only when both a true thyroglossal duct cyst and a separate thyroid lesion are excised in the same session with clear documentation of each. |
| 38700 | Suprahyoid lymphadenectomy | A separate cervical lymph node procedure; bundling edits generally prevent separate reporting with 60200 unless a distinct, medically necessary lymphadenectomy is performed and documented apart from the thyroid excision itself. |
Bundling Alert
Because 60200 carries a full 90-day global period, any related post-operative visits, suture removal, or routine wound checks within that window are bundled into the original payment and cannot be separately billed with an E/M code unless modifier -24 is appended for a genuinely unrelated issue.³ Audit risk is highest when documentation suggests a more extensive lobectomy was actually performed but under-coded as 60200, or conversely when a truly discrete excision is up-coded to a lobectomy code; the operative note’s description of tissue extent removed is the deciding factor payers will request.

Bilateral Billing Rules
Since the thyroid is a single midline gland rather than a paired organ, the standard 150% bilateral payment adjustment does not apply to 60200, and modifier -50 is not appropriate for this code. If disease affecting both lobes requires excision of separate lesions from each lobe in the same session, documentation should clearly support why a single 60200 unit captures the full scope of work, since Medicare generally allows only one unit regardless of how many discrete lesions are excised.
🏷️ Modifier Reference
| Modifier | Name | When to Apply |
|---|---|---|
| -RT | Right Side | Append when the excised cyst, adenoma, or isthmus work is anatomically confined to or centered on the right thyroid lobe, per payer-specific convention. |
| -LT | Left Side | Append when the excised cyst, adenoma, or isthmus work is anatomically confined to or centered on the left thyroid lobe, per payer-specific convention. |
| -50 | Bilateral | Not typically applicable, since the thyroid is a single midline gland and the bilateral surgery payment adjustment does not apply to this code. |
| -22 | Increased Procedural Services | Append when documentation supports substantially greater work than typical, such as dense scarring from prior surgery or an unusually large or deeply invasive lesion requiring extended dissection. |
| -51 | Multiple Procedures | Applies when 60200 is billed with other separately payable procedures in the same operative session, subject to standard multiple-procedure payment reduction. |
| -59 | Distinct Service | Use to indicate 60200 represents a distinct procedural service from another same-session code when NCCI edits would otherwise bundle them, if documentation supports separate medical necessity. |
| -78 | Return to Operating Room for a Related Procedure | Append when the patient requires an unplanned return to the OR within the 90-day global period for a complication related to the original excision, such as post-operative hematoma evacuation. |
| -79 | Unrelated Procedure by Same Physician During Postoperative Period | Append when the same surgeon performs a distinct, unrelated procedure during the 90-day global period following the original thyroid excision. |
| -76 | Repeat Procedure by Same Physician | Applies when the same surgeon must repeat the identical excision procedure, such as for recurrent cyst formation, and the repeat falls outside the original global period. |
🩺 Common ICD‑10‑CM Pairings
Primary Diagnosis Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| E04.1 | Nontoxic single thyroid nodule | No | The most common indication for a discrete cyst/adenoma excision when the nodule is functionally non-hyperactive and confirmed or suspected benign. |
| D34 | Benign neoplasm of thyroid gland | No | Applies when pathology confirms a true benign adenoma rather than a simple colloid cyst, supporting the “adenoma” language in the code descriptor directly. |
| E04.2 | Nontoxic multinodular goiter | No | Supports medical necessity when a discrete dominant nodule within a multinodular gland is excised without addressing the remainder of the gland. |
| E05.20 | Thyrotoxicosis with toxic multinodular goiter without thyrotoxic crisis or storm | No | Applies when the excised nodule is hyperfunctioning; documentation should clarify why a discrete excision rather than lobectomy was selected in this scenario. |
| E06.9 | Thyroiditis, unspecified | No | Supports cases where a cystic or nodular thyroiditis-related lesion is excised for diagnostic or symptomatic reasons. |
Secondary Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| R91.8 | Other nonspecific abnormal finding of lung field | No | Not typically applicable to this procedure; included here only if an incidental unrelated imaging finding is separately documented and coded. |
| R59.0 | Localized enlarged lymph nodes | No | Supports documentation when a concurrent, separately excised cervical lymph node is evaluated alongside the thyroid excision. |
Etiology / Complication
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| E89.0 | Postprocedural hypothyroidism | No | Applies to a subsequent encounter if the patient develops hypothyroidism following excision of a significant portion of functioning thyroid tissue. |
| J38.00 | Paralysis of vocal cords and larynx, unilateral, partial | No | Applies if a post-operative complication involving recurrent laryngeal nerve injury is diagnosed at a subsequent encounter within or after the global period. |
Coding Specificity Reminder
Always confirm the pathology report’s final diagnosis before finalizing the primary code, since a preoperative diagnosis of a nontoxic nodule may be revised to a malignant or thyroiditis-related diagnosis after histologic review. Specify laterality only where it is clinically documented and relevant to reimbursement policy, since the thyroid ICD-10-CM codes themselves generally do not carry laterality distinctions but the CPT modifier selection may.
🏥 MS‑DRG Considerations
When performed during an inpatient admission, CPT 60200’s facility-side ICD-10-PCS equivalent (Excision root operation on the thyroid gland, lobe, or isthmus) maps to MS-DRG 625-627, Thyroid, Parathyroid and Thyroglossal Procedures. The specific DRG tier within that triad — with MCC, with CC, or without CC/MCC — is driven entirely by the severity of secondary diagnoses present on the encounter, such as postoperative hypocalcemia, vocal cord paralysis, or unrelated comorbid conditions, rather than by the surgical approach or extent of thyroid tissue removed. Coders should ensure all clinically significant secondary diagnoses are captured to accurately reflect case complexity and appropriate DRG assignment.
🔧 ICD‑10‑PCS Equivalents
| PCS Code | Full Description | Modality |
|---|---|---|
| 0GB80ZZ | Excision of Thyroid Gland Lobe, Right, Open Approach | Open Surgical |
| 0GB90ZZ | Excision of Thyroid Gland Lobe, Left, Open Approach | Open Surgical |
| 0GBC0ZZ | Excision of Thyroid Gland Isthmus, Open Approach | Open Surgical |
| 0GBD0ZZ | Excision of Thyroid Gland, Open Approach | Open Surgical |
PCS Character Analysis
| Position | Character | Value | Definition |
|---|---|---|---|
| 1 | Section | 0 | Medical and Surgical section, since this represents an operative alteration of body tissue rather than imaging or another ancillary service. |
| 2 | Body System | G | Endocrine System, the ICD-10-PCS body system classification encompassing the thyroid, parathyroid, pituitary, and adrenal glands. |
| 3 | Root Operation | B | Excision — cutting out or off a portion of a body part without replacement, matching the CPT descriptor’s removal of a discrete cyst, adenoma, or isthmus segment. |
| 4 | Body Part | 8/9/C/D | Right Lobe, Left Lobe, Isthmus, or whole Thyroid Gland, selected according to which specific anatomic structure was excised during the operative encounter. |
| 5 | Approach | 0 | Open approach, reflecting the standard cervical incision technique used for this procedure rather than a percutaneous or endoscopic method. |
| 6 | Device | Z | No device value applies, since no implant, graft, or other device is left in place following a simple excision procedure. |
| 7 | Qualifier | Z | No qualifier value applies to a straightforward excision without an additional procedural characteristic requiring further specification. |
Root Operation Comparison
- Excision (root operation B) is distinguished from Resection (root operation T) by the fact that Excision removes only a portion of a body part, whereas Resection would apply to entire lobe or gland removal codes like total thyroid lobectomy.
- Excision differs from Destruction (root operation 5) in that Excision physically removes tissue for pathologic examination, while Destruction eliminates tissue in place without removing it, such as with radiofrequency ablation of a thyroid nodule.
📝 Coding Examples
Example 1
Clinical Scenario: A 52-year-old woman presents with a palpable 2.5 cm right thyroid nodule confirmed benign on fine-needle aspiration biopsy. Given persistent discomfort and cosmetic concern, she elects surgical excision. The surgeon performs a low collar incision, carefully dissects the discrete, well-encapsulated adenoma from the surrounding right thyroid parenchyma, and confirms an intact capsule margin on gross inspection. The remainder of the right lobe and the left lobe are left undisturbed, and the wound is closed in layers with a small drain placed.
| Field | Code | Rationale |
|---|---|---|
| CPT | 60200--RT | A discrete adenoma excision confined to the right lobe without removal of the surrounding lobe tissue, appropriately reported as 60200 rather than a lobectomy code. |
| PDx | D34 | Confirms the pathologic diagnosis of a benign thyroid adenoma supporting the excision performed. |
Note
Verify the pathology report confirms a discrete adenoma rather than diffuse nodular change before finalizing D34 as primary; if the final pathology instead shows extensive multinodular involvement, query the surgeon on whether the coded procedure still accurately reflects the operative extent.
Example 2
Clinical Scenario: A 61-year-old man requires elective tracheostomy for anticipated prolonged ventilator weaning. During the procedure, the surgeon encounters a prominent thyroid isthmus overlying the planned tracheostomy site and transects the isthmus to gain adequate surgical access, without excising any thyroid lobe tissue. The tracheostomy is then completed in standard fashion. Both procedures are performed in the same operative session by the same surgeon.
| Field | Code 1 | Rationale |
|---|---|---|
| CPT 1 | 60200 | Isthmus transection performed as a distinct component of gaining surgical access, separately reportable from the tracheostomy itself. |
| CPT 2 | 31600 | Tracheostomy, planned; the primary procedure for which the isthmus transection provided necessary surgical exposure. |
| PDx | J96.10 | Chronic respiratory failure, unspecified whether with hypoxia or hypercapnia, supporting medical necessity for the tracheostomy procedure. |
Warning
Some payers and NCCI edits consider isthmus transection performed solely for tracheostomy access to be inherently bundled into the tracheostomy code itself; verify current payer-specific bundling policy before reporting 60200 separately in this scenario, since audit findings in this exact fact pattern have gone both ways depending on documentation specificity.
Example 3
Clinical Scenario: A 39-year-old woman with a history of Hashimoto’s thyroiditis presents with a new, rapidly enlarging cystic mass in the left thyroid lobe. Ultrasound-guided fine-needle aspiration yields inconclusive cytology, prompting surgical excision for definitive diagnosis. The surgeon excises the discrete cystic lesion along with a small rim of surrounding thyroid tissue, preserving the majority of the left lobe. Final pathology confirms a benign colloid cyst with background chronic lymphocytic thyroiditis. The patient is discharged the same day and returns for a routine wound check at postoperative day 10, which is included in the global package.
| Field | Code | Rationale |
|---|---|---|
| CPT | 60200--LT | Discrete cystic lesion excision confined to the left lobe with preservation of the remaining lobe, appropriately distinguished from a partial lobectomy. |
| PDx | E06.3 | Autoimmune thyroiditis, capturing the underlying Hashimoto’s disease process associated with the cystic change. |
Global period reminder
⚠️ Common Coding Pitfalls
- Pitfall 1: Reporting 60200 when the operative note actually describes removal of an entire thyroid lobe rather than a discrete lesion, which should instead be coded as 60210 or 60220 depending on extent. Carefully review the specimen description and remaining gland tissue documented in the operative note before finalizing code selection.
- Pitfall 2: Failing to append modifier -22 when documentation supports significantly increased procedural complexity, such as reoperative scarring or an unusually invasive lesion, resulting in under-reimbursement for the additional physician work performed.
- Pitfall 3: Separately billing routine post-operative wound checks or suture removal visits occurring within the 90-day global period, which are bundled into the original 60200 payment and not separately payable absent a genuinely unrelated issue.
- Pitfall 4: Confusing 60200’s isthmus-transection application with 60280’s thyroglossal duct cyst excision, since these target anatomically distinct structures — the thyroid gland itself versus an embryologic duct remnant — despite both occurring in the same general neck region.
- Pitfall 5: Omitting laterality modifiers (-RT/-LT) when payer policy requires them for accurate claims adjudication, even though the ICD-10-CM diagnosis codes themselves typically do not carry laterality distinctions for thyroid conditions.
- Pitfall 6: Assuming the standard bilateral surgery 150% payment adjustment applies to 60200, when in fact the thyroid’s midline single-gland anatomy means bilateral indicator 0 applies and modifier -50 is generally inappropriate for this code.
