Summary & Overview
CPT 26205: Excision of Metacarpal Cyst with Autologous Graft
CPT code 26205 represents a surgical excision of a cyst or benign tumor of the metacarpal bones on the dorsal hand with placement of an autologous graft to fill the defect. This code captures a combined approach addressing both lesion removal and reconstructive grafting, which has implications for operative planning, resource utilization, and billing across surgical and hand-specialty practices. Nationally, clarity on coding for excision plus grafting matters for appropriate reimbursement and claims adjudication when care involves both lesion removal and reconstructive work.
Key payers in this analysis 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 primary elements that define the service line. The publication outlines common payer coverage considerations and commonly applied modifiers (list provided elsewhere), and explains how the procedure maps to surgical service reporting. It also highlights where data is not available in the input for diagnosis mapping, related codes, and specific payer policy details. This summary is intended for a national audience of coding professionals, surgical providers, and revenue cycle stakeholders seeking a clear, practical reference for CPT code 26205.
Billing Code Overview
CPT code 26205 describes an open surgical procedure in which the provider incises the skin over the dorsal aspect of the hand to remove a cyst or benign tumor arising from the metacarpal bones. The procedure includes harvesting and applying an autologous graft from another part of the patient's body to fill the resulting osseous or soft-tissue cavity to promote healing.

Clinical & Coding Specifications
Clinical Context
A 45-year-old right-hand-dominant patient presents with a slowly enlarging, painless dorsal hand mass overlying the second metacarpal. Imaging (hand radiographs and ultrasound or MRI) demonstrates a well-circumscribed ganglion or benign metacarpal bone cyst without aggressive features. Conservative management failed and the patient elects operative excision. In the operating room under regional block or general anesthesia, the surgeon makes a dorsal hand incision, dissects to the cyst or benign tumor of the metacarpal, performs enucleation or curettage of the lesion, and harvests an autologous bone graft (commonly from the distal radius or iliac crest) to pack the defect to promote structural integrity and healing. Hemostasis is achieved, the wound is closed, and a sterile dressing and splint are applied. Typical workflow includes preoperative evaluation, imaging review, informed consent documenting autograft use, intraoperative specimen handling if pathology is performed, postoperative pain control, and hand therapy referral as indicated. Typical site of service is an outpatient ambulatory surgery center or hospital outpatient department. Service type is minor to intermediate hand surgery with bone grafting and excision of a benign dorsal metacarpal lesion.
