Summary & Overview
CPT 26210: Excision of Bone Cyst or Tumor, Phalanx of Finger
CPT code 26210 denotes surgical excision of a bone cyst or tumor from a phalanx of the finger and is used to bill for operative hand surgery involving incision and removal of intraosseous lesions. Nationally, accurate coding for this procedure affects surgical quality metrics, reimbursement for ambulatory and hospital-based hand surgery, and claims adjudication for musculoskeletal and oncologic indications. Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
This publication explains the clinical context of CPT code 26210, typical sites of service, and common utilization scenarios. Readers will find a concise description of the procedure and service setting, an overview of payer coverage patterns and common modifiers used with this code, and benchmarks and policy considerations relevant to billing and claims processing. The content is intended to inform clinical coding staff, revenue cycle professionals, and policy analysts about the primary uses of CPT code 26210, coding consistency issues that commonly arise, and areas where payer guidance or policy updates may affect claim outcomes. Data not available in the input will be noted where appropriate.
Billing Code Overview
CPT code 26210 describes a surgical procedure in which the provider makes an incision in the skin of an affected finger to remove a bone cyst or tumor from a phalanx bone. The service type is operative hand surgery focused on excision of a lesion within a phalangeal bone. The typical site of service for this procedure is an ambulatory surgery center or hospital outpatient or inpatient surgical setting, depending on case complexity and patient needs.

Clinical & Coding Specifications
Clinical Context
A 45-year-old right-hand dominant patient presents with progressive localized pain, swelling, and a palpable mass over the proximal phalanx of the index finger. Plain radiographs demonstrate a radiolucent, well-circumscribed lesion within the phalanx consistent with an intraosseous ganglion, unicameral bone cyst, or benign bone tumor. After discussion of diagnostic and therapeutic options, the hand surgeon schedules a minor open procedure in an ambulatory surgery center to incise the skin, create a cortical window in the phalanx, and remove the cystic or tumorous material for symptom relief and histopathologic diagnosis.
The clinical workflow includes preoperative evaluation (history, focused hand examination, imaging review), informed consent with discussion of risks (infection, stiffness, recurrence, neurovascular injury), perioperative marking of the affected digit, sterile preparation, regional or local anesthesia with or without monitored anesthesia care, a longitudinal or transverse incision over the lesion, cortical window creation, curettage and lesion removal, irrigation, possible bone grafting or packing if indicated, layered wound closure, and application of a sterile dressing and digital splint. Postoperative instructions address wound care, pain control, activity restrictions, and planned follow-up for suture removal and pathology review.
