🦋 CPT 60260 — Thyroidectomy, Removal Of All Remaining Thyroid Tissue Following Previous Removal Of A Portion Of Thyroid
Quick Reference
wRVU: 17.80 | Global Period: 090 | Assistant Payable: Yes | Bilateral Indicator: 0
Rule: CPT 60260 has a 90-day global period, meaning standard postoperative care is included in the primary reimbursement. A bilateral indicator of 0 means the 150% payment adjustment for bilateral procedures does not apply, as the code describes removing all remaining tissue, inherently making the -50 modifier inappropriate. If staged during the postoperative period of the initial partial removal, modifier -58 must be appended to ensure payment.
📋 Clinical Description
CPT 60260 describes a completion thyroidectomy, which involves the surgical excision of all residual thyroid tissue in a patient who previously underwent a partial thyroidectomy, such as a lobectomy. During this procedure, the surgeon makes an incision in the lower neck (usually through the prior surgical scar), carefully identifying and dissecting the remaining thyroid tissue while preserving surrounding vital structures like the parathyroid glands and recurrent laryngeal nerves. This service differs from CPT 60240 (Thyroidectomy, total or complete), which describes a full removal in a single operative session on a previously unoperated gland, and CPT 60220 (Total thyroid lobectomy, unilateral), which describes the initial removal of just one lobe.
The primary clinical goal of this procedure is to manage malignant pathology discovered after an initial partial removal, or to address persistent and recurring endocrine conditions. Because scar tissue from the initial surgery alters normal neck anatomy, dissecting the recurrent laryngeal nerve and parathyroid glands is generally more complex than in a primary total thyroidectomy. The code explicitly accounts for the extra physician work required to navigate this altered surgical field. When reporting this service, it is critical to ensure that the patient’s history confirms a previous, distinct operative session where a portion of the thyroid was excised.
This procedure may be performed in the following clinical contexts:
- Completion surgery for malignancy — The most common indication occurs when final pathology from an initial lobectomy unexpectedly reveals thyroid cancer, necessitating the removal of the remaining lobe to prevent recurrence.
- Recurrent or persistent hyperthyroidism — Patients with Graves’ disease or toxic multinodular goiter who do not respond adequately to partial resection or radioactive iodine may require excision of the remaining glandular tissue.
- Progressive symptomatic goiter — A patient who previously had a lobectomy for a benign goiter may develop compensatory enlargement in the remaining lobe, leading to compressive symptoms such as dysphagia or tracheal deviation.
- Prophylactic removal in high-risk patients — Individuals with a newly discovered genetic mutation (e.g., RET oncogene) after a prior partial thyroidectomy may undergo this procedure to eliminate the risk of medullary thyroid carcinoma.
🔬 Anatomical & Procedural Considerations
| Variant | Mechanism | Key Notes |
|---|---|---|
| Traditional Open Completion | An incision is made in the anterior lower neck, often utilizing the prior surgical scar. The surgeon dissects through the strap muscles, navigates dense adhesions, and isolates the remaining lobe for en bloc removal. | This is the standard approach for CPT 60260. The presence of fibrotic scar tissue from the primary surgery significantly increases the risk of injury to the recurrent laryngeal nerve and parathyroid vascular supply. |
| Endoscopic/Minimally Invasive | Utilizes smaller incisions and video assistance to visualize and extract the residual thyroid tissue. This can sometimes be performed transaxillary to avoid additional neck scarring. | If an endoscopic approach is used exclusively, unlisted codes may be required if no specific CPT exists, though many payers allow 60260 if the clinical work is functionally identical. Confirm payer policies regarding endoscopic thyroidectomies. |
| With Parathyroid Autotransplantation | During the excision of the remaining thyroid tissue, a devascularized parathyroid gland is identified, minced, and reimplanted into the sternocleidomastoid or forearm muscle to preserve calcium regulation. | The autotransplantation is reported separately using add-on code CPT 60512. This is a critical step when the parathyroid glands cannot be safely preserved in situ due to extensive scarring. |
Clinical Pearl
Because the anatomy is heavily distorted by scar tissue from the initial lobectomy, identifying the recurrent laryngeal nerve is technically demanding. Many surgeons utilize intraoperative nerve monitoring (CPT 95940) alongside CPT 60260 to reduce the risk of vocal cord paralysis; however, note that Medicare and many commercial payers often bundle the nerve monitoring or consider it an integral part of the primary procedure unless specific LCD criteria are met.
✅ Procedure Includes
- Re-opening of the previous cervical incision and division of the platysma and strap muscles.
- Lysis of adhesions and scar tissue from the prior partial thyroidectomy.
- Identification, isolation, and preservation of the recurrent laryngeal nerve and parathyroid glands.
- Complete excision of all remaining thyroid tissue (usually the contralateral lobe and/or isthmus).
- Achieving hemostasis, placement of surgical drains (if necessary), and multi-layer closure of the surgical site.
- Routine postoperative care within the 90-day global period.
❌ Excludes / Do Not Report Together
| Code | Description | Relationship |
|---|---|---|
| 60240 | Thyroidectomy, total or complete | Mutually exclusive. Code 60240 is for a primary total thyroidectomy, whereas 60260 is strictly for the removal of remaining tissue after a prior partial excision. |
| 60220 | Total thyroid lobectomy, unilateral; with or without isthmusectomy | Mutually exclusive on the same remaining lobe. 60220 is an initial procedure, while 60260 addresses the secondary completion procedure. |
| 60270 | Thyroidectomy, including substernal thyroid; sternal split or transthoracic approach | Mutually exclusive. If the remaining tissue is substernal and requires a sternotomy for extraction, 60270 or its variants should be evaluated instead. |
| 69990 | Microsurgical techniques, requiring use of operating microscope | Bundled. The use of a microscope or magnifying loupes for nerve identification during thyroid surgery is considered inclusive to the primary procedure. |
Bundling Alert
CPT 60260 carries a 90-day global period. If this completion thyroidectomy is performed during the global period of the initial lobectomy (e.g., CPT 60220), you must append modifier -58 to indicate it is a staged or related procedure planned prospectively or necessitated by pathology results. Failure to append the correct modifier will result in a global period denial. Additionally, routine wound care and standard post-operative management are bundled and cannot be billed as separate Evaluation and Management (E/M) visits.

Bilateral Billing Rules
A bilateral indicator of 0 signifies that the concept of bilateral billing does not apply to this code. Because CPT 60260 inherently describes the removal of all remaining tissue (which is naturally unilateral at the time of this secondary surgery), appending modifier -50 will likely trigger a denial or processing error. If laterality needs to be specified to match the diagnosis, modifiers -RT or -LT may be appended depending on payer preference.
🏷️ Modifier Reference
| Modifier | Name | When to Apply |
|---|---|---|
| -RT | Right Side | Apply if the remaining tissue being removed is localized exclusively to the right lobe to add anatomic specificity. |
| -LT | Left Side | Apply if the remaining tissue being removed is localized exclusively to the left lobe to add anatomic specificity. |
| -58 | Staged | Apply if the completion thyroidectomy is performed during the 90-day global period of the initial partial thyroidectomy (e.g., due to positive cancer pathology). |
| -22 | Increased Procedural Services | Apply if the re-operation is exceptionally difficult or requires significantly more time than typical due to severe adhesions or altered anatomy (requires strong operative report documentation). |
| -59 | Distinct Procedural Service | Apply to indicate the procedure was distinct or independent from other non-E/M services performed on the same day, if bundling edits apply. |
| -51 | Multiple Procedures | Apply if performed during the same operative session as another non-exempt primary surgical procedure with a higher RVU value. |
| -78 | Return to OR | Apply if the procedure was an unplanned return to the operating room for a related complication (e.g., post-op hemorrhage requiring re-exploration and completion) during the global period. |
| -79 | Unrelated Procedure | Apply if the completion thyroidectomy is entirely unrelated to the primary procedure that initiated the current global period. |
🩺 Common ICD‑10‑CM Pairings
Primary Diagnosis Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| C73 | Malignant neoplasm of thyroid gland | Yes | The most common indication for a completion thyroidectomy following a lobectomy that revealed cancer. |
| D34 | Benign neoplasm of thyroid gland | No | Used when the remaining tissue has developed a benign nodule or adenoma causing symptoms. |
| E04.2 | Nontoxic multinodular goiter | No | Applicable when persistent goiter tissue causes compressive symptoms or significant cosmetic deformity. |
| E05.00 | Thyrotoxicosis with diffuse goiter without thyrotoxic crisis or storm | No | Used for Graves’ disease patients who fail medical management and require total glandular removal. |
| E05.20 | Thyrotoxicosis with toxic multinodular goiter without thyrotoxic crisis or storm | No | Used when remaining hyperfunctioning nodules cause persistent systemic thyrotoxicosis. |
Secondary Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| Z85.850 | Personal history of malignant neoplasm of thyroid | No | Can be used as a secondary code to establish medical necessity for prophylactic completion surgery. |
| R13.10 | Dysphagia, unspecified | No | Supports medical necessity when remaining goiter tissue compresses the esophagus. |
Etiology / Complication
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| E89.0 | Postprocedural hypothyroidism | No | Indicates the patient’s hypothyroid status as a direct result of previous partial glandular excision. |
| J38.01 | Paralysis of vocal cords and larynx, unilateral | No | May be reported if the patient suffered vocal cord paralysis from the previous surgery, increasing the complexity of the current re-operation. |
Coding Specificity Reminder
Ensure the diagnosis code reflects the current reason for the completion surgery. If the initial surgery was for a benign nodule (e.g., D34) but the pathology returned as malignant, report C73 for the completion thyroidectomy. Always code to the highest degree of certainty and verify that the laterality of the diagnosis (if applicable) matches any anatomic modifiers used on the CPT code.
🏥 MS‑DRG Considerations
For inpatient claims, CPT 60260 directly influences the MS-DRG assignment, typically routing to MS-DRG 625 (Thyroid, Parathyroid, and Thyroglossal Procedures with MCC), MS-DRG 626 (with CC), or MS-DRG 627 (without CC/MCC), depending on the patient’s secondary diagnoses. Since 2021, CMS removed the National Coverage Determination (NCD) for many specific thyroid procedures, transferring coverage jurisdiction to local Medicare Administrative Contractors (MACs)1. Therefore, coders must consult their specific MAC’s Local Coverage Determination (LCD) policies to verify covered diagnosis pairings and medical necessity requirements for completion thyroidectomies, especially regarding the use of intraoperative nerve monitoring. Ensure that the principal diagnosis driving the MS-DRG perfectly aligns with the clinical justification for the surgical re-intervention.

| 1 | Section | 0 | Medical and Surgical. This defines the broad category of the procedure. |
| 2 | Body System | G | Endocrine System. Specifies the anatomical system being operated on. |
| 3 | Root Operation | T | Resection. Defined as cutting out or off, without replacement, all of a body part. |
| 4 | Body Part | K / L | Right Thyroid Gland Lobe / Left Thyroid Gland Lobe. Specifies the exact glandular portion removed. |
| 5 | Approach | 0 / 4 | Open / Percutaneous Endoscopic. Defines the method used to reach the operative site. |
| 6 | Device | Z | No Device. Indicates no device was left in place at the conclusion of the procedure. |
| 7 | Qualifier | Z | No Qualifier. Indicates no additional specific attributes apply to this procedure. |
Root Operation Comparison
Use the root operation Resection when the entirety of the remaining lobe is removed during the completion thyroidectomy, as the PCS definition of resection requires removal of all of a specified body part.
If only a portion of the remaining lobe is removed (which is clinically rare in a completion thyroidectomy but possible), the root operation Excision (cutting out or off, without replacement, a portion of a body part) must be used instead.
📝 Coding Examples
Example 1
Clinical Scenario: A 45-year-old female underwent a left thyroid lobectomy 3 weeks ago for a suspicious nodule. The final pathology report returned positive for papillary thyroid carcinoma. The patient returns to the operating room for a planned right completion thyroidectomy to ensure complete removal of the gland and mitigate cancer recurrence. The surgeon uses the previous neck incision, dissects the dense scar tissue, and successfully removes the entire right lobe.
| Field | Code | Rationale |
|---|---|---|
| CPT | 60260--58 | Code 60260 captures the removal of the remaining thyroid tissue. Modifier -58 is required because the procedure is staged/related and falls within the 90-day global period of the initial lobectomy. |
| PDx | C73 | Malignant neoplasm of thyroid gland is the primary medical necessity for the completion surgery. |
Note
Because this is a staged procedure occurring during an active global period, failing to append modifier -58 will result in an immediate denial.
Example 2
Clinical Scenario: A 60-year-old male with a history of a right partial thyroidectomy 10 years ago presents with severe dysphagia and a visibly enlarged neck. Imaging confirms a massive multinodular goiter in the remaining left lobe. The surgeon performs a completion thyroidectomy. Due to the extreme size of the goiter and dense fibrotic adhesions from the decade-old surgery, the procedure takes twice the typical operative time and requires meticulous micro-dissection to spare the recurrent laryngeal nerve.
| Field | Code | Rationale |
|---|---|---|
| CPT 1 | 60260--22 | Code 60260 accurately describes the completion thyroidectomy. Modifier -22 is appended to account for the significantly increased procedural complexity and prolonged operative time. |
| PDx | E04.2 | Nontoxic multinodular goiter describes the condition necessitating the excision. |
Warning
When appending modifier -22, ensure the operative report explicitly details the extreme difficulty, exact extra time spent, and the physiological reasons for the complexity to survive payer audits.
Example 3
Clinical Scenario: A 38-year-old female patient with a history of a right lobectomy 5 years ago for benign disease presents with new-onset hyperthyroidism. After failing medical management for Graves’ disease, she is taken to the ASC for a completion thyroidectomy. The remaining left lobe is entirely excised without complication.
| Field | Code | Rationale |
|---|---|---|
| CPT | 60260 | Represents the removal of all remaining thyroid tissue. No global period modifiers are needed because the initial surgery was 5 years ago. |
| PDx | E05.00 | Thyrotoxicosis with diffuse goiter without thyrotoxic crisis or storm supports the indication for surgery. |
Note
⚠️ Common Coding Pitfalls
- Pitfall 1: Billing CPT 60240 (Total thyroidectomy) instead of 60260 when the patient has already had a previous lobectomy. CPT 60240 is exclusively for intact, previously unoperated thyroid glands.
- Pitfall 2: Forgetting to append modifier -58 when a completion thyroidectomy is performed shortly after the initial lobectomy due to positive cancer pathology. This will cause the claim to bundle into the initial surgery’s global period.
- Pitfall 3: Appending modifier -50 (Bilateral) to CPT 60260. The descriptor inherently implies the removal of the remaining tissue, making it a unilateral procedure at the time of the secondary surgery.
- Pitfall 4: Billing separate E/M services for routine postoperative wound checks or staple removal. These services are included in the 90-day global package and are not separately reimbursable.
- Pitfall 5: Unbundling intraoperative nerve monitoring (CPT 95940) without checking MAC LCD policies. Many payers consider monitoring the recurrent laryngeal nerve an inclusive component of complex thyroid surgery.
- Pitfall 6: Reporting CPT 60260 alongside CPT 60220 on the same date of service. If both lobes are removed in a single operative session, report CPT 60240 (Total thyroidectomy) instead.
