Summary & Overview
CPT 21552: Excision of Subcutaneous Mass, Neck or Anterior Chest, ≥3 cm
CPT code 21552 represents the surgical excision of a subcutaneous mass 3 cm or larger in the neck or anterior chest with submission of the specimen for pathologic diagnosis. This code is used to bill a discrete operative procedure that addresses potentially diagnostic and therapeutic needs for patients with palpable or imaging-detected masses in these anatomic sites. Nationally, accurate coding of this procedure affects surgical reporting, pathology utilization, and specialty care workflows.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines common billing patterns, typical sites of service, and the clinical context in which the code is used. Readers will find concise benchmarks on utilization and coverage practices, discussion of billing nuances tied to site and specimen handling, and clinical context that explains when a surgeon may use this code versus other excision or biopsy codes. The summary highlights areas where coding clarity supports appropriate claims submission and where payer policies typically address medical necessity and documentation requirements.
This national overview is intended for surgical providers, billing professionals, and policy analysts seeking a clear, practice-oriented explanation of CPT code 21552 and its implications for surgical and pathology workflows.

Clinical & Coding Specifications
Clinical Context
A 52-year-old patient presents to an outpatient surgical clinic with a slowly enlarging, painless subcutaneous mass on the anterior neck measuring approximately 3.5 cm on physical exam. The lesion is firm, mobile, and clinically suspicious for a benign or malignant soft-tissue neoplasm. After review of history and focused exam, the surgeon schedules a minor operative procedure to excise the lesion under local anesthesia with conscious sedation in an ambulatory surgery center. The provider removes the lesion in its entirety with narrow margins, submits the specimen for pathological analysis, controls hemostasis, and closes the incision primarily. Postoperative instructions include wound care, pain control, and return precautions; pathology results drive further oncologic management if indicated.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure | Use when a distinct E/M visit is performed and documented on the same day as the excision prior to the procedure |
51 | Multiple procedures | Use when more than one distinct procedure is performed during the same operative session |
