Summary & Overview
CPT 60270: Total Thyroidectomy with Mediastinal Extension
CPT code 60270 represents a total thyroidectomy that includes removal of thyroid tissue extending below the breastbone (mediastinal extension). This is a higher-complexity surgical procedure used for large goiters, cysts, or thyroid disease with extension into the upper chest and has implications for surgical planning, perioperative risk management, and facility resource use nationwide. The code matters nationally because it maps to higher resource utilization, potential inpatient admission, and specific surgical credentialing and coding conventions.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of clinical context, typical sites of service, and what to expect in billing and claims workflows for 60270. The publication presents benchmarks and payment considerations, common billing modifiers, and policy updates that affect authorization and coverage for extensive thyroid surgery. Clinical context covers indications for mediastinal extension removal and factors that influence site-of-service decisions. The content is written for hospital administrators, coding professionals, and clinical leaders seeking a clear, national-level reference for CPT code 60270 and its operational and policy implications.

Billing Code Overview
CPT code 60270 describes a total thyroidectomy with extension into the mediastinum, in which the provider removes the thyroid gland including the portion that extends below the breastbone. This procedure is used for more complex benign conditions (for example, a very large goiter or cyst) and for malignant or other conditions that extend into the upper chest.
Service type: Surgical — Major Head and Neck/Endocrine Surgery
Typical site of service: Inpatient hospital or outpatient surgical center depending on case complexity and need for postoperative monitoring.
Clinical & Coding Specifications
Clinical Context
A typical patient is a 55-year-old female presenting with progressive anterior neck fullness, dysphagia, and dyspnea on exertion. Imaging (neck ultrasound and CT chest) demonstrates a multinodular goiter with substernal extension into the superior mediastinum and tracheal compression. Fine-needle aspiration cytology of dominant nodules showed benign colloid nodules, but the size and compressive symptoms indicate surgical management. The surgical workflow includes preoperative endocrine and anesthetic assessment, voice and calcium baseline documentation, informed consent for total thyroidectomy with possible sternotomy extension, operating room preparation with general endotracheal anesthesia, intraoperative neural monitoring when used, removal of the thyroid gland including the intrathoracic extension, hemostasis, possible placement of a drain, and postoperative monitoring for airway compromise, hypocalcemia, and recurrent laryngeal nerve dysfunction. Typical sites of service are hospital inpatient or hospital outpatient surgery center depending on extent; more complex cases with substernal extension often require inpatient admission. Service type: major head and neck surgical procedure (total thyroidectomy with substernal extension).
