Summary & Overview
CPT 26499: Surgical Tendon Transfer for Claw Finger
CPT code 26499 represents an unlisted tendon transfer procedure for correction of claw finger deformity. Used when no more specific CPT code applies, this entry captures surgical techniques such as rerouting a flexor tendon to restore extensor function. Nationally, unlisted procedure codes like 26499 matter because they require clinical documentation and often require additional review for medical necessity and reimbursement adjudication.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, guidance on common billing and documentation expectations for unlisted surgical codes, and an outline of typical sites of service. The publication summarizes benchmark considerations for payment review, common modifier usage patterns (data not available in the input), and operational implications for coding teams when submitting claims that lack a directly corresponding CPT descriptor.
This summary is intended to help coding professionals, revenue integrity teams, and clinical leaders understand the clinical purpose of CPT code 26499, the payer landscape to expect at a national level, and the types of documentation and claim submission details that commonly accompany unlisted hand surgery procedures.
Billing Code Overview
CPT code 26499 describes a surgical procedure to correct a claw finger deformity using a technique that is not represented by a more specific code. The procedure typically involves rerouting or repositioning tendons—for example, relocating a flexor tendon from the palmar side to the dorsolateral side of the finger so that the tendon functions as an extensor from its new position.

Service type: Surgical corrective tendon transfer for claw finger deformity

Typical site of service: Ambulatory surgical center or hospital operating room for hand surgery
Clinical & Coding Specifications
Clinical Context
A 52-year-old right-hand–dominant patient presents with progressive contracture of the ring and little fingers consistent with claw deformity causing functional impairment of grasp and finger extension. Conservative measures (splinting, occupational therapy) failed to restore digital extension. The hand surgeon evaluates range of motion, tendon function, and neurovascular status, confirms intact proximal flexor tendons with imbalance of extrinsic/intrinsic forces, and elects surgical tendon transfer to rebalance finger extension.
Preoperative workflow includes history and focused hand exam, informed consent, assessment for anesthesia (regional block or general), and preoperative imaging only if bony pathology is suspected. Intraoperative steps typically include exposure of the flexor tendon in the palm, detachment and rerouting of the tendon to the dorsal/apical aspect of the finger or extensor mechanism, tensioning and fixation to convert a flexor into a functioning extensor. The procedure is coded as 26499 when no more specific CPT code describes the exact tendon transfer technique.
Postoperative workflow includes immobilization in a dorsal blocking splint, early supervised therapy to control adhesions and retrain tendon function, wound checks, and staged progression to active extension and strengthening. Documentation should support the medical necessity of a non–listed procedure code and describe operative details, indication, laterality, anesthesia, and any concurrent procedures.
