🦋 CPT 60225 — Total Thyroid Lobectomy, Unilateral; With Contralateral Subtotal Lobectomy, Including Isthmusectomy
Quick Reference
wRVU: 14.42 | Global Period: 090 | Assistant Payable: Yes | Bilateral Indicator: 0
Rule: CPT 60225 inherently includes bilateral work because it involves a total lobectomy on one side and a subtotal lobectomy on the contralateral side. The bilateral indicator of 0 means that the 150% payment adjustment for bilateral procedures does not apply, and modifiers like -50 should not be appended.
📋 Clinical Description
CPT 60225 describes the surgical removal of one complete lobe of the thyroid gland, along with a partial removal (subtotal lobectomy) of the opposite lobe, and the complete excision of the isthmus that connects them. The surgeon makes an incision in the anterior neck to access the thyroid gland, carefully identifying and preserving the parathyroid glands as well as the recurrent laryngeal nerves. After mobilizing the gland, the entire primary lobe is excised, the isthmus is removed in its entirety, and a significant portion of the contralateral lobe is resected, leaving only a small remnant of thyroid tissue intact before achieving hemostasis and closing the incision.
This procedure represents a near-total thyroidectomy and is typically performed for conditions where removing the vast majority of the thyroid tissue is medically necessary, but leaving a small remnant is clinically appropriate to maintain some endogenous thyroid function or to avoid bilateral recurrent laryngeal nerve risks. Compared to CPT 60220 (total unilateral lobectomy), this comprehensive code includes the additional surgical work of a contralateral subtotal lobectomy. Conversely, compared to CPT 60240 (total thyroidectomy), it explicitly leaves a functional remnant of tissue on the contralateral side rather than removing the gland completely.
This procedure may be performed in the following clinical contexts:
- Multinodular Goiter — Performed when multiple nodules extensively affect both lobes but a small amount of healthy tissue can safely be preserved on one side to maintain some native hormone production.
- Thyroid Cancer — Selected for certain low-risk or strictly localized malignancies where a near-total thyroidectomy is preferred by the surgical team over a complete total thyroidectomy to reduce postoperative hypoparathyroidism risks.
- Hyperthyroidism — Used in specific cases of Graves’ disease or toxic goiter when radioactive iodine therapy is contraindicated or unsuccessful, removing just enough tissue to halt excess hormone overproduction.
- Indeterminate Nodules — Utilized when highly suspicious nodules are present bilaterally, requiring an extensive but not entirely complete removal for definitive histopathological diagnosis while awaiting final pathology results.
🔬 Anatomical & Procedural Considerations
| Variant | Mechanism | Key Notes |
|---|---|---|
| Recurrent Laryngeal Nerve Preservation | Careful micro-dissection and the possible utilization of intraoperative nerve monitoring technology. | The recurrent laryngeal nerve must be visually identified and meticulously preserved on both sides of the neck to prevent devastating postoperative vocal cord paralysis or airway compromise. |
| Parathyroid Gland Sparing | Direct visual identification of the parathyroid glands and careful preservation of their delicate native blood supply. | The parathyroid glands are mobilized and left in situ whenever possible; however, if they become devascularized during the dissection, they may require reimplantation or autotransplantation, which is reported separately with CPT 60512. |
| Substernal Extension | Careful delivery of the enlarged thyroid gland upward from the superior mediastinum using blunt dissection techniques. | If the goiter extends deeply into the mediastinum requiring a full median sternotomy, a different approach or distinct additional codes might be necessary, though standard cervical approaches are typically sufficient. |
Clinical Pearl
When coding CPT 60225, you must ensure the operative report explicitly details three distinct anatomical actions: the complete removal of one entire lobe, the complete removal of the isthmus, and the subtotal (partial) removal of the contralateral lobe. If the surgeon ultimately decides intraoperatively to remove the entire contralateral lobe as well, leaving no remnant behind, the procedure must be coded as CPT 60240 (total thyroidectomy) instead. Accurate distinction between these two codes is critical for audit compliance and appropriate reimbursement, as they represent different extents of surgical resection.
✅ Procedure Includes
- Complete surgical excision of one entire thyroid lobe (unilateral total lobectomy).
- Complete excision of the thyroid isthmus connecting the right and left lobes.
- Partial excision of the contralateral thyroid lobe (subtotal lobectomy), deliberately leaving a tissue remnant.
- Routine surgical exploration, identification, and preservation of the recurrent laryngeal nerves.
- Routine surgical exploration, identification, and preservation of the parathyroid glands.
- Layered closure of the cervical surgical incision, placement of standard surgical drains if necessary, and routine hemostasis.
❌ Excludes / Do Not Report Together
| Code | Description | Relationship |
|---|---|---|
| 60220 | Total thyroid lobectomy, unilateral; with or without isthmusectomy | CPT 60225 inherently includes all the work described by CPT 60220, as it involves a total unilateral lobectomy plus the additional contralateral subtotal resection. |
| 60240 | Thyroidectomy, total or complete | CPT 60240 represents the complete removal of all thyroid tissue, whereas CPT 60225 explicitly leaves a subtotal remnant; these codes are mutually exclusive based on the extent of the excision. |
| 60212 | Partial thyroid lobectomy, unilateral; with contralateral subtotal lobectomy, including isthmusectomy | CPT 60212 involves only a partial removal of the primary lobe, not the total removal required to successfully justify coding CPT 60225. |
| 60500 | Parathyroidectomy or exploration of parathyroid(s) | Routine exploration and identification of the parathyroids is strictly bundled into all major thyroidectomy codes unless a distinct, independent pathology requires a separate parathyroid excision. |
Bundling Alert
CPT 60225 carries a comprehensive 090-day global period, meaning all routine pre-operative work and standard postoperative care related to the neck surgery are strictly bundled into the primary procedure code and cannot be billed separately. National Correct Coding Initiative (NCCI) edits universally bundle lesser thyroid procedures, such as partial excisions or standalone isthmusectomies, into this comprehensive code. Modifier -59 should only be appended if a distinctly independent and entirely separate procedure is performed at a completely different anatomic site or during a separate patient encounter on the exact same day.

Bilateral Billing Rules
CPT 60225 inherently describes a comprehensive bilateral procedure because its descriptor specifically involves surgical work on both the ipsilateral (total lobectomy) and the contralateral (subtotal lobectomy) sides of the thyroid gland. Therefore, the bilateral indicator is definitively set to “0”, meaning you should never append modifier -50 or utilize modifiers -RT and -LT to indicate a bilateral service. Reimbursement is strictly based on the comprehensive nature of the code without any additional bilateral payment adjustments.
🏷️ Modifier Reference
| Modifier | Name | When to Apply |
|---|---|---|
| -RT | Right Side | Apply if the primary total lobectomy was performed on the right side and the subtotal on the left, though this is generally unnecessary for reimbursement as the code is inherently bilateral. |
| -LT | Left Side | Apply if the primary total lobectomy was performed on the left side and the subtotal on the right, strictly for informational purposes depending on your specific commercial payer policy. |
| -50 | Bilateral | Do not apply under any circumstances; this comprehensive code inherently includes extensive bilateral work within its primary descriptor. |
| -E1 | Upper Left Eyelid | Not applicable; this modifier is explicitly reserved for eyelid procedures, while this code represents a major neck surgery. |
| -E2 | Lower Left Eyelid | Not applicable; this modifier is explicitly reserved for eyelid procedures, while this code represents a major neck surgery. |
| -E3 | Upper Right Eyelid | Not applicable; this modifier is explicitly reserved for eyelid procedures, while this code represents a major neck surgery. |
| -E4 | Lower Right Eyelid | Not applicable; this modifier is explicitly reserved for eyelid procedures, while this code represents a major neck surgery. |
| -25 | Significant E/M | Apply to an Evaluation and Management service on the exact same day only if it is significant, separately identifiable, and clearly goes above and beyond the usual pre-operative care. |
| -24 | Unrelated E/M | Apply to an Evaluation and Management service performed during the 090-day global period only if it is completely medically unrelated to the primary thyroid surgery. |
| -51 | Multiple Procedures | Apply if another distinct, non-bundled surgical procedure is performed during the exact same operative session by the same physician. |
| -59 | Distinct Service | Apply to indicate that a procedure or service was distinctly independent from other non-bundled services performed on the exact same day to bypass automated NCCI edits. |
| -52 | Reduced Services | Apply if the planned near-total thyroidectomy procedure was partially reduced or structurally eliminated at the physician’s discretion due to unforeseen anatomical challenges. |
| -53 | Discontinued | Apply if the surgical procedure was successfully started but completely discontinued due to extenuating circumstances or sudden severe patient instability. |
| -58 | Staged | Apply if a planned subsequent procedure is performed during the global period, such as strategically completing a total thyroidectomy after initial surgical pathology results confirm malignancy. |
| -78 | Return to OR | Apply if the patient requires an unplanned, immediate return to the operating room for a related procedure, such as the emergency control of a severe post-operative neck hematoma. |
| -79 | Unrelated Procedure | Apply if a completely unrelated, distinct surgical procedure is performed by the exact same physician during the active 090-day global postoperative period. |
🩺 Common ICD‑10‑CM Pairings
Primary Diagnosis Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| E04.2 | Nontoxic multinodular goiter | No | Often the primary indication for the surgical removal of an enlarged, nodular gland causing severe compressive symptoms in the neck. |
| C73 | Malignant neoplasm of thyroid gland | Yes | Used when the procedure is specifically performed as a definitive cancer treatment, though complete total thyroidectomies are generally more common for overt malignancies. |
| E05.00 | Thyrotoxicosis with diffuse goiter without thyrotoxic crisis or storm | No | Reported when surgical intervention is specifically chosen to manage severe hyperthyroidism that has proven entirely refractory to standard medical therapy. |
| E01.1 | Iodine-deficiency related multinodular (endemic) goiter | No | Indicates a significantly enlarged goiter resulting directly from chronic iodine deficiency requiring definitive surgical intervention to alleviate symptoms. |
| D34 | Benign neoplasm of thyroid gland | No | Used when dominant nodules are confirmed strictly benign via biopsy but require surgical excision due to their massive size or local compressive symptoms. |
Secondary Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| E89.0 | Postprocedural hypothyroidism | No | Often applied in the postoperative evaluation period when the patient strictly requires long-term thyroid hormone replacement therapy following the extensive glandular resection. |
| J39.8 | Other specified diseases of upper respiratory tract | No | Used as a secondary diagnosis if a massively enlarged goiter is causing documented physical tracheal compression or severe anatomical deviation. |
Etiology / Complication
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| J95.89 | Other postprocedural complications and disorders of respiratory system, not elsewhere classified | Yes | Applied if there is a severe postoperative complication such as acute respiratory distress requiring immediate clinical intervention. |
| R49.0 | Dysphonia | No | Can be used to accurately report postoperative hoarseness, which may clinically suggest recurrent laryngeal nerve neuropraxia or permanent injury. |
Coding Specificity Reminder
Always strive to code to the absolute highest level of specificity for thyroid neoplasms by clearly distinguishing between malignant (C73), benign (D34), or uncertain behavior. When coding complex goiters, accurately differentiate between nontoxic uninodular, nontoxic multinodular (E04.2), and toxic multinodular diagnoses. Ensure any secondary physical manifestations, such as compressive dysphagia (R13.10), are also successfully captured on the claim if they are thoroughly documented in the provider’s notes.
🏥 MS‑DRG Considerations
In the inpatient setting, procedures coded with CPT 60225 typically group to MS-DRG 625 (Thyroid, Parathyroid, and Thyroglossal Procedures with MCC), 626 (with CC), or 627 (without CC/MCC). When verifying coverage, you must carefully compare your specific Medicare Administrative Contractor’s (MAC) Local Coverage Determination (LCD) or National Coverage Determination (NCD) for thyroid surgeries directly against the CMS Medicare Physician Fee Schedule (MPFS) Lookup tool. The MPFS explicitly lists this CPT code as an active, fully payable procedure with a 090-day global period and a base work RVU of 14.42. Your specific MAC LCD will outline the required medical necessity criteria, such as documented compressive symptoms, failure of medical management, or suspected malignancy, which must align perfectly with the active status and global period parameters defined in the national PFS database to ensure successful hospital reimbursement.

PCS Character Analysis
| Position | Character | Value | Definition |
|---|---|---|---|
| 1 | Section | 0 | Medical and Surgical. This broad section covers all standard operative surgical procedures. |
| 2 | Body System | G | Endocrine System. Specifies the exact anatomical body system functionally involved in the procedure. |
| 3 | Root Operation | T | Resection. Denotes the total, complete removal of a specific body part (used exclusively for the total lobectomy side). |
| 4 | Body Part | K | Thyroid Gland Lobe, Right. Identifies the specific anatomical structure being surgically targeted. |
| 5 | Approach | 0 | Open. Indicates the procedure was physically performed via an open anterior neck incision. |
| 6 | Device | Z | No Device. Confirms that absolutely no permanent device is surgically left in place at the conclusion. |
| 7 | Qualifier | Z | No Qualifier. Serves as a standard placeholder character when no additional specialized qualification is needed. |
Root Operation Comparison
- “Resection” is strictly used for the side where the complete lobe is entirely removed, as it conceptually involves the total eradication of that specific defined body part (the entire lobe).
- “Excision” is strictly used for the subtotal lobectomy side, as only a partial portion of the body part (the contralateral lobe) is surgically removed while leaving a tissue remnant.
- In inpatient PCS coding, both the total lobectomy (Resection) and the subtotal lobectomy (Excision) may need to be coded entirely separately to fully capture the extensive bilateral nature of the procedure described by the single outpatient CPT code.
📝 Coding Examples
Example 1
Clinical Scenario: A 45-year-old female presents with a large, highly symptomatic right-sided multinodular goiter and several smaller nodules located on the left lobe. The patient extensively complains of significant difficulty swallowing solid foods. In the operating room, the surgeon performs a complete right total thyroid lobectomy, totally removes the connecting isthmus, and carefully excises approximately 80% of the left thyroid lobe. The recurrent laryngeal nerves are successfully monitored and meticulously preserved. Complete hemostasis is achieved and the neck incision is securely closed in layers.
| Field | Code | Rationale |
|---|---|---|
| CPT | 60225 | The procedure clearly documents a total unilateral lobectomy heavily combined with a contralateral subtotal lobectomy and a complete isthmusectomy. |
| PDx | E04.2 | Nontoxic multinodular goiter is definitively the primary underlying reason for the extensive surgical resection. |
Note
Ensure the operative report explicitly details the exact extent of the left-sided subtotal removal (e.g., leaving a 2-gram remnant) to firmly justify this code over a standard total thyroidectomy.
Example 2
Clinical Scenario: A 60-year-old male with a long history of Graves’ disease entirely refractory to intense medical management undergoes surgery. The surgeon performs a complete left total thyroid lobectomy and an isthmusectomy. On the right side, the surgeon successfully removes the vast majority of the lobe, deliberately leaving a small 2-gram remnant of functioning thyroid tissue specifically to physically protect the right parathyroid glands.
| Field | Code | Rationale |
|---|---|---|
| CPT 1 | 60225 | The detailed procedure notes describe exactly the anatomical removals legally required for this code (total left, subtotal right, and complete isthmus). |
| CPT 2 | 95336 | If intraoperative recurrent laryngeal nerve monitoring is performed and thoroughly documented, it may be legitimately coded separately depending on the payer’s rules. |
| PDx | E05.00 | Thyrotoxicosis with diffuse goiter without crisis correctly identifies the definitive Graves’ disease clinical indication. |
Warning
Example 3
Clinical Scenario: A patient with a highly suspected right lobe thyroid malignancy rapidly undergoes a right total thyroid lobectomy. During the procedure, the surgeon visually identifies suspicious, abnormal tissue in the left lobe and decides to prudently perform a subtotal lobectomy on the left side as well, removing the entire isthmus in the process. Final surgical pathology confirms papillary thyroid carcinoma exclusively in the right lobe and completely benign tissue in the left.
| Field | Code | Rationale |
|---|---|---|
| CPT | 60225 | The massive extent of the resection perfectly matches the AMA descriptor for a unilateral total and a contralateral subtotal lobectomy. |
| PDx | C73 | Malignant neoplasm of the thyroid gland is positively confirmed by pathology and should be heavily reported as the primary diagnosis. |
Global period reminder
Any routine postoperative evaluation visits for simple wound checks or standard drain removal within the next 90 days are strictly bundled into the global surgical package and should not be billed separately.
⚠️ Common Coding Pitfalls
- Pitfall 1: Confusing CPT 60225 with CPT 60240 (Total Thyroidectomy). If the surgeon thoroughly removes both lobes completely without leaving any remnant behind, you must exclusively report CPT 60240. Reporting 60225 when a complete total thyroidectomy was actually performed constitutes inaccurate and non-compliant coding.
- Pitfall 2: Inappropriately appending bilateral modifiers to the claim. Since the explicit code descriptor inherently includes “contralateral subtotal lobectomy,” the procedure is inherently bilateral by definition. Adding modifier -50, -LT, or -RT is completely redundant and may cause automatic claim denials.
- Pitfall 3: Unbundling the routine isthmusectomy. The complete removal of the thyroid isthmus is explicitly included verbatim in the code descriptor for CPT 60225. Billing any additional code for the isthmusectomy is severe unbundling and highly non-compliant.
- Pitfall 4: Failing to document the actual remnant tissue. If the operative report simply states “subtotal lobectomy” but does not physically describe the specific remnant left behind, a rigorous auditor may forcefully question whether a total thyroidectomy was actually performed. Clear, objective documentation of the remnant size is crucial.
- Pitfall 5: Separate billing for routine parathyroid exploration. Identifying and safely preserving the parathyroid glands is a standard, expected component of major thyroid surgery. You absolutely cannot bill CPT 60500 unless a diseased parathyroid gland is specifically targeted and entirely excised for separate pathology.
- Pitfall 6: Ignoring the strict 90-day global period rules. Billing for standard postoperative evaluation and management services without properly appending the appropriate modifier (like -24 for unrelated clinical issues) will definitively result in automatic, swift denials from Medicare and commercial payers.
