Summary & Overview
CPT 26517: Hand Joint Stabilization for Two Digits
CPT code 26517 denotes a surgical stabilization procedure addressing instability at the metacarpophalangeal and proximal interphalangeal joint region for two digits. This code captures a targeted reconstructive technique in which the joint capsule is incised and reattached under increased tension to restore alignment and reduce laxity. Nationally, this code is relevant to hand surgeons, orthopedic and plastic surgery practices, ambulatory surgical centers, and hospital surgical services because it defines a specific operative intervention that affects coding accuracy, clinical documentation, and payment pathways.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical intent and service setting, guidance on how the procedure is typically documented, and pointers to benchmarking and policy considerations where available. The publication offers context on procedural attribution, typical sites of service, and documentation elements that support coding of 26517. Data not available in the input will be noted as such in dedicated sections of the full publication.
Billing Code Overview
CPT code 26517 describes a surgical procedure to treat instability of joints in two digits between the metacarpals and proximal phalanges. The operation involves incising the joint capsule and reattaching it with increased tension to the metacarpal and phalanx to restore stability and function.
-
Service type: Surgical procedure on the hand focusing on joint stabilization of two digits
-

Clinical & Coding Specifications
Clinical Context
A 45-year-old right-hand–dominant patient presents with chronic radial deviation and symptomatic instability of the metacarpophalangeal joints of the index and middle fingers after a sports-related rollback injury. Conservative management including splinting, activity modification, and corticosteroid injection failed to restore stability. Preoperative evaluation includes hand surgeon assessment, plain radiographs to exclude fracture or advanced arthritis, and documentation of instability on physical exam with joint laxity and subluxation. The patient is scheduled for operative repair under regional block with optional regional sedation in an ambulatory surgical center. The surgeon performs capsulorrhaphy by incising the joint capsule of the unstable metacarpophalangeal joints and tightening and reattaching the capsule to the metacarpal and proximal phalanx to restore stability. Postoperative workflow includes short PACU recovery, hand immobilization in a splint, wound care instructions, and early referral to hand therapy for range-of-motion and strengthening according to surgeon protocol. Typical sites of service are an ambulatory surgical center or hospital outpatient department for elective hand surgery. The service type is surgical, reconstructive/repair of small joints of the hand using capsular tightening techniques.
