Summary & Overview
CPT 20220: Superficial Bone Biopsy
CPT code 20220 denotes a superficial bone biopsy, a diagnostic procedure to obtain bone tissue for pathological or microbiological examination. This code is used nationally to document and bill for procedures aimed at evaluating suspected bone lesions, infections, or other localized bone pathology when sampling from superficial sites is indicated. Accurate coding supports appropriate clinical documentation, care coordination, and claims adjudication across payers.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, common sites of service, and the role of this procedure in diagnostic workups. The publication also summarizes typical billing considerations, commonly reported modifiers, and how payers may categorize the service for coverage and payment purposes.
This report is intended for a national audience and will help clinicians, coders, and revenue cycle professionals understand when CPT code 20220 is applicable, what settings it is most often performed in, and what types of information to expect in payer guidance and benchmark reporting. Data not provided in the input (such as specific payer fee schedules or utilization benchmarks) are noted where applicable.
Billing Code Overview
CPT code 20220 describes a superficial bone biopsy, a procedure to obtain a sample of bone tissue for pathological or microbiological analysis when a superficial bone lesion or suspected infection requires diagnostic evaluation. The service type is a diagnostic tissue sampling procedure. The typical site of service for this procedure is an outpatient surgical center or hospital outpatient department; it may also be performed in an ambulatory clinic with appropriate sterile technique and staffing.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a history of chronic osteomyelitis and progressive localized bone pain presents to an orthopedic clinic after persistent symptoms despite antibiotic therapy. Imaging (plain radiographs and MRI) demonstrates a suspicious cortical lesion in the distal tibia with surrounding marrow changes. The orthopedic surgeon schedules a superficial bone biopsy (CPT 20220) to obtain a tissue sample for microbiology and histopathology to confirm infection versus neoplasm.
The clinical workflow: the patient is assessed pre-procedure for anticoagulation status and consented. The procedure is typically performed in an ambulatory surgery center or hospital minor procedure suite under local anesthesia with or without conscious sedation. The surgeon prepares a sterile field, makes a small incision over the cortical abnormality, and obtains a superficial bone specimen using curettage or a small trephine. Specimens are sent for Gram stain, aerobic/anaerobic cultures, fungal/mycobacterial cultures as indicated, and histologic analysis. Post-procedure hemostasis and wound closure are performed, postoperative instructions are given, and results guide further management such as targeted antibiotic therapy or oncologic referral.
