CPT code 25920 represents surgical separation of the hand from the forearm at the wrist joint — a wrist-level amputation. This code is used to document and bill for definitive amputation procedures of the hand performed in operative settings. Nationally, wrist-level amputations are significant for trauma care, management of severe infection or ischemia, and certain oncologic or reconstructive scenarios, making accurate coding important for clinical tracking and reimbursement.

Key payers referenced include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical service captured by 25920, the typical care setting for the procedure, and the common billing modifiers associated with upper-extremity surgical claims (input lists). The publication provides benchmarks and coding context where available and notes when input data is not provided. It also outlines clinical and administrative considerations relevant to claims submission and payer coverage determinations, including typical sites of service and the procedural nature of the code. Data not available in the input will be identified as such in the relevant sections of the full publication.
