Summary & Overview
CPT 28003: Drainage of Multiple Infected Bursal Spaces Under Foot Fascia
CPT code 28003 represents surgical drainage of multiple infected bursal spaces beneath the foot fascia, a procedure used to treat deep soft-tissue infections that can involve or threaten the tendon sheath. Nationally, this code is relevant to inpatient and outpatient surgical settings where foot infections require operative intervention to prevent spread and preserve function. Payers commonly managing coverage for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn clinical context for when surgical bursal drainage is billed, typical sites of service, and how major payers approach coverage and billing for procedures addressing deep foot infections. The publication provides benchmarks and policy summaries relevant to reimbursement and coding practice, highlights common modifiers used with surgical services, and explains implications for documentation and claims processing. Data not available in the input for specific associated taxonomies, ICD-10 diagnosis mappings, and payer-specific policy details will be noted where applicable. This summary is intended for a national audience of clinicians, coding professionals, and policy analysts seeking concise guidance on the clinical and billing context of CPT code 28003.

Typical site of service: Ambulatory surgical center or hospital operating room, or other surgical setting appropriate for foot soft-tissue infection management
Clinical & Coding Specifications
Clinical Context
A 48-year-old patient presents to the outpatient podiatry clinic with progressive swelling, erythema, and focal fluctuance over the dorsum and plantar aspect of the forefoot for 48–72 hours, with increasing pain and difficulty bearing weight. The patient has a low-grade fever and localized warmth. Physical exam suggests multiple infected interdigital and subfascial bursae with possible extension toward the tendon sheaths. The clinical workflow includes history and focused foot exam, point-of-care ultrasound to identify fluid collections beneath the plantar fascia and between tendon planes, pre-procedure informed consent, sterile preparation and local anesthesia or monitored anesthesia care as indicated, percutaneous drainage and irrigation of multiple bursal spaces (partial or complete evacuation), fluid sent for Gram stain and culture, post-procedure wound care and dressing, and scheduling of follow-up for wound checks and culture-directed antibiotics.
