🩺CPT 60240 - Thyroidectomy, Total or Complete

Code Description

Official Descriptor: Thyroidectomy, total or complete

This code represents the surgical removal of the entire thyroid gland. The procedure is performed through a standard cervical collar incision (Kocher incision) in the lower anterior neck. The surgeon carefully identifies and preserves critical structures including the recurrent laryngeal nerves and parathyroid glands while completely excising all thyroid tissue from both lobes and the isthmus.

Procedure Overview

Surgical Approach

The total thyroidectomy procedure involves a systematic approach to safely remove the entire thyroid gland. The surgeon makes a transverse cervical incision approximately 2-3 cm above the sternal notch, following natural skin lines for optimal cosmetic results. After raising subplatysmal flaps and dividing the strap muscles, the thyroid gland is exposed and mobilized.

Key Surgical Steps

  • Exposure and Identification: The thyroid gland is exposed and the middle thyroid veins are ligated and divided
  • Superior Pole Dissection: The superior thyroid vessels are individually ligated close to the thyroid capsule to preserve external branch of superior laryngeal nerve
  • Inferior Pole Dissection: The inferior thyroid vessels are identified and preserved when possible to maintain parathyroid gland blood supply
  • Recurrent Laryngeal Nerve Identification: The recurrent laryngeal nerve is carefully identified and preserved throughout its course in the tracheoesophageal groove
  • Parathyroid Preservation: All visible parathyroid glands are identified and preserved with their blood supply intact
  • Isthmus Division: The thyroid isthmus is divided and the tracheal surface is cleared
  • Specimen Removal: The entire thyroid gland is removed and sent for pathological examination
  • Hemostasis and Closure: Meticulous hemostasis is achieved and the wound is closed in layers

Includes

The following services and components are included in CPT 60240 and should NOT be reported separately:

  • Complete removal of both thyroid lobes
  • Removal of the thyroid isthmus

Assistant Surgeon Guidelines

Assistant Surgeon: PAYABLE

CPT 60240 allows payment for assistant surgeon services when medically necessary.

When Assistant Surgeon is Medically Necessary:

  • Large goiter requiring extensive dissection
  • Invasive malignancy with surrounding tissue involvement
  • Reoperative surgery with significant scarring
  • Patient comorbidities requiring additional assistance
  • Teaching hospital requirements

Documentation Requirements:

  • Medical necessity must be documented in operative report
  • Assistant surgeon must dictate separate operative report
  • Both surgeons must maintain separate medical records

Reimbursement:

  • Assistant surgeon typically receives 16% of primary surgeon fee
  • Medicare pays 16% of physician fee schedule amount

MS-DRG Assignment

Inpatient Setting: Total thyroidectomy is typically performed as an outpatient procedure. When performed inpatient, MS-DRG assignment depends on:

Possible MS-DRGs (if inpatient):

  • MS-DRG 282-284: Thyroid, Parathyroid and Thyroglossal Procedures
    • 282: With MCC (Major Complication/Comorbidity)
    • 283: With CC (Complication/Comorbidity)
    • 284: Without CC/MCC

Common Inpatient Indications:

  • Large substernal goiter
  • Invasive thyroid cancer
  • Significant comorbidities requiring monitoring
  • Complications requiring extended stay

Note: Most total thyroidectomies are performed in outpatient hospital or ambulatory surgery center settings.

HCC Risk Adjustment

Hierarchical Condition Category (HCC) Impact:

CPT 60240 itself does not directly impact HCC risk adjustment. However, the diagnosis codes reported with the procedure may contribute to HCC assignment:

  • C73 (Thyroid Cancer): Maps to HCC category for malignant neoplasms
    • Contributes to risk adjustment in Medicare Advantage and ACA plans
  • E05.xx (Thyrotoxicosis): May map to HCC categories for endocrine disorders
    • Severity and complications affect HCC assignment

Documentation for HCC:

  • Document all comorbid conditions
  • Specify cancer type and stage when applicable
  • Document severity of thyroid disease
  • Capture all chronic conditions for accurate RAF score

OPPS/ASC Payment

Outpatient Prospective Payment System (OPPS)

APC Assignment: APC 5361 - Level 1 Laparoscopy and Related Services (2025)

Status Indicator: J1 - Hospital Part B services paid through a comprehensive APC

Payment Considerations:

  • Packaged payment under Comprehensive APC
  • Payment includes all services provided during encounter
  • Separate payment may be made for certain high-cost devices or drugs

ASC Payment:

  • Covered in Ambulatory Surgery Center setting
  • Payment based on ASC fee schedule
  • Patient cost-sharing applies

  • 88332-88333 - Permanent section pathology

Modifier 59 Usage:

Use modifier 59 only when no more specific modifier is appropriate and procedures are:

  • Performed at different anatomic sites
  • Performed at separate patient encounters on same day
  • Distinct and separate from the primary procedure
