Summary & Overview
CPT 25065: Excisional Biopsy of Superficial Soft Tissue, Forearm/Wrist
CPT code 25065 represents an excisional biopsy of suspicious superficial soft tissue in the forearm or wrist submitted for laboratory pathology. The code captures a common diagnostic surgical service that guides definitive diagnosis and subsequent treatment decisions for soft-tissue masses or lesions. Nationally, accurate coding for biopsies like 25065 affects clinical documentation, coverage determinations, and claims adjudication across public and commercial payers.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and the procedural intent behind the code. The publication provides benchmarks where available, highlights relevant billing and policy considerations affecting reimbursement and claim processing, and outlines how documentation supports medical necessity for pathology-directed procedures.
This summary is designed for clinicians, billing professionals, and policy analysts seeking clarity on when CPT code 25065 applies, how it is used in clinical workflows, and what to expect from payer coverage and administrative processes at a national level.
Billing Code Overview
CPT code 25065 describes an excisional biopsy in which the provider removes a sample of suspicious tissue from the superficial soft tissues of the forearm and/or wrist and submits it to a laboratory for pathological analysis. This procedure is a diagnostic surgical service intended to obtain tissue for histologic evaluation to determine the nature of a lesion.

Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents to an outpatient orthopedic clinic with a 2-week history of a palpable, tender, firm lesion on the dorsal aspect of the forearm near the wrist. The lesion is suspicious for a benign soft-tissue tumor (for example, ganglion cyst, lipoma, or epidermal inclusion cyst) or possible malignant lesion given irregular margins and recent growth. The provider performs a focused history and physical, documents lesion size, mobility, neurovascular status, and obtains informed consent for a diagnostic soft-tissue biopsy.
The procedure is performed in an ambulatory procedure room under local anesthesia. The provider isolates the lesion, makes a small incision, and uses either punch or excisional technique to remove a representative tissue sample from the superficial soft tissues of the forearm/wrist. Hemostasis is achieved, and the specimen is placed in appropriate fixative and submitted to the pathology laboratory for histologic analysis. The site is dressed and aftercare instructions provided. The pathology report guides definitive diagnosis and subsequent management, which may include observation, excision, referral to oncology, or further imaging and procedures.
