CPT code 27390 denotes an open tenotomy of a single hamstring tendon, a targeted surgical procedure used to divide or release one of the hamstring muscles (biceps femoris, semitendinosus, or semimembranosus) between the knee and hip. Nationally, this code captures discrete orthopedic tendon-release operations performed in operative settings and is relevant for hospitals, ambulatory surgery centers, and orthopedic surgical practices managing hamstring contractures, chronic tendinopathy, or select traumatic injuries.

Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the service, typical sites of care, and common billing considerations tied to procedural coding. The publication summarizes benchmark elements and coding relationships where available and flags areas where input data are not provided.

The report covers clinical indications and operative scope implicit in the code, payer coverage scope at a national level, and practical coding context for revenue cycle teams and practice managers. It also outlines which additional elements are not present in the input (such as associated taxonomies, ICD-10 diagnoses, and related codes) so readers can identify gaps and plan for supplemental documentation or policy review.
