Summary & Overview
CPT 25915: Forearm Stump Pincer-Grasp Reconstruction
CPT code 25915 describes a specialized surgical reconstruction performed on an upper-extremity amputation stump to separate the ulna and radius and create a pincer-like grasp driven by the pronator teres muscle. The code captures procedures aimed at restoring prehension and improving functional outcomes for patients with forearm amputations. Nationally, this code matters because it represents complex reconstructive surgery with implications for surgical coding, coverage determinations, and post-operative rehabilitation pathways.
Key payers referenced in standard analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and the types of billing considerations that commonly accompany reconstructive upper-extremity amputation procedures. The publication also outlines expected benchmarks where available, common modifier usage provided in the input, and implementation considerations relevant to surgeons, coders, and payers. The content is intended to clarify what CPT code 25915 represents, why it is billed, and what stakeholders should note about service delivery and coding classification. Data not available in the input: specific associated taxonomies, ICD-10 diagnoses, related codes, payer-specific coverage policies, and service-line financial benchmarks.
Billing Code Overview
CPT code 25915 describes a surgical procedure in which the provider separates the ulna and radius bones of a forearm stump remaining after amputation to create a pincer- or forceps-like grasp controlled by the pronator teres muscle. This procedure is a form of reconstructive or functional amputation revision intended to improve prehension and prosthetic or native limb utility.
-
Service type: Surgical reconstruction of an upper-extremity amputation stump to create a functional pincer grasp.
-
Typical site of service: Hospital operating room or ambulatory surgical center, depending on clinical status and perioperative needs.
Clinical & Coding Specifications
Clinical Context
A 45-year-old male with a previous transradial forearm amputation presents for surgical reconstruction to improve prehension and independence with activities of daily living. The patient has a well-healed distal forearm stump with intact pronator teres muscle function and desires improved pinch function for self-care and vocational tasks. Preoperative evaluation includes focused vascular and neurologic assessment of the residual limb, discussion of goals with the patient and prosthetist, and planning for stump revision and dynamic osteoplastic separation of the radius and ulna.
The operative workflow begins with regional or general anesthesia and standard sterile preparation of the forearm. The surgeon makes an incision over the forearm stump, elevates soft tissue flaps, and mobilizes the radius and ulna to create separate, vascularized bone segments. Tendon transfer or redirection of the pronator teres is performed to provide active rotational control, allowing the two bony segments to act as a pincer (forceps-like) grasp. Hemostasis, soft tissue coverage, and possible local flap or skin grafting are performed to achieve a durable stump. Postoperatively, the patient undergoes wound checks, pain control, and early occupational therapy focusing on range of motion, strengthening of the pronator teres–driven grasp, and training with a prosthetic or compensatory devices if indicated.
Typical site of service is an inpatient or outpatient hospital operating room or ambulatory surgery center staffed for limb reconstruction. The procedure is performed by orthopedic or plastic surgeons with expertise in limb salvage and reconstructive techniques, often involving a multidisciplinary team including anesthesia, nursing, and occupational therapy.
