Summary & Overview
CPT 26568: Metacarpal or Phalanx Bone Lengthening (Osteodistraction)
CPT code 26568 denotes surgical bone lengthening of a metacarpal or phalanx, commonly performed via osteodistraction. The code captures procedures that deliberately separate bone segments to stimulate new bone growth and restore length or correct deformity in the hand. Nationally, this code is relevant for orthopedic and hand surgeons, hospital billing departments, and payers managing surgical authorizations and post-operative care coverage. Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a compact resource on clinical purpose and billing context for CPT code 26568, including typical settings of care and the service type. The publication summarizes common payer considerations, billing nuances, and benchmarking topics relevant to surgical lengthening of hand bones. It also outlines clinical context such as indications for osteodistraction and typical perioperative settings. Data not provided in the input — including specific payer policies, authorization requirements, and associated diagnosis codes — are noted as unavailable. The content is intended for national audiences involved in clinical coding, medical billing, and surgical care planning.
Billing Code Overview
CPT code 26568 describes a surgical procedure to lengthen a metacarpal or phalanx bone using techniques such as osteodistraction, in which the surgeon gradually separates the two segments of a bone so new bone forms in the gap. The procedure is a bone lengthening surgery of the hand.
Service type: Surgical — orthopedic/hand surgery procedure
Typical site of service: Inpatient or outpatient surgical setting, commonly performed in an ambulatory surgery center or hospital operating room depending on clinical complexity and patient needs.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adolescent or adult with a short metacarpal or phalanx causing functional impairment, congenital hand difference, post‑traumatic bone shortening, or brachydactyly. The patient presents to a hand surgery clinic with complaints of limited range of motion, cosmetic concern, pain from joint imbalance, or difficulty with grip and pinching. Preoperative evaluation includes history and physical, focused hand and neurovascular exam, radiographs to measure bone length and alignment, and discussion of osteodistraction technique, expected timeline for distraction and consolidation, and potential need for staged procedures.
The clinical workflow: the patient undergoes preoperative clearance and informed consent. In the operating room under regional block or general anesthesia, the hand surgeon performs an osteotomy of the affected metacarpal or phalanx and applies an external or internal distractor device. Immediate postoperative care includes dressing, device instruction, and analgesia. The patient returns frequently during the distraction phase (daily to weekly) for device adjustments and monitoring of regenerate bone and soft tissues. After desired length is achieved, the consolidation phase follows until radiographic union, at which time device removal may occur in the clinic or operating room. Rehabilitation with hand therapy is provided throughout consolidation and after device removal.
