Summary & Overview
CPT 28054: Surgical Biopsy of Toe or Finger Joint
CPT code 28054 denotes a surgical biopsy of a toe or finger joint, where a provider makes an incision to obtain tissue for diagnostic analysis. This code identifies a targeted orthopedic or podiatric procedure that supports diagnosis of inflammatory, infectious, or neoplastic joint conditions. Nationally, precise coding for digital joint biopsy matters because it impacts claim adjudication, clinical documentation, and appropriate identification of surgical services in ambulatory and hospital outpatient settings.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Clinical & Coding Specifications
Clinical Context
A patient presents to an outpatient orthopedic or podiatry clinic with persistent pain, swelling, or a suspicious lesion localized to a toe or finger interphalangeal joint. After history, focused examination, and radiographic evaluation (X-ray, possibly ultrasound), the clinician determines that a synovial or capsular lesion, chronic inflammatory arthritis nodule, or focal bone/cartilage abnormality requires histologic diagnosis. The patient is consented for a diagnostic joint biopsy of the affected toe or finger joint. The procedure is performed in a procedure room or minor surgery suite under local anesthesia, with sterile technique. The provider makes a small incision into the joint, obtains a tissue sample, achieves hemostasis, and closes the incision with suture or adhesive. Specimens are sent to pathology. Post-procedure instructions cover wound care, activity restrictions, and signs of infection. Typical sites of service are outpatient clinic procedure rooms or ambulatory surgical centers; the service type is a minor surgical biopsy of a digital joint.
