Summary & Overview
CPT 28890: Extracorporeal Shock Wave Therapy for Plantar Fascia
CPT code 28890 represents extracorporeal shock wave therapy directed to the sole of the foot to stimulate healing of the plantar fascia, typically performed with ultrasound guidance and under regional or general anesthesia. Nationally, this code captures a minimally invasive, procedure-based approach for refractory plantar fasciitis and is relevant for payer coverage policies, utilization tracking, and clinical pathway design.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, common billing pathways, and the operational settings where the service is delivered. The publication outlines national reimbursement benchmarks where available, common modifiers used in claims, and payer policy themes that affect coverage decisions. Clinical context explains the procedure indication and typical perioperative considerations, while policy context summarizes how major payers and Medicare approach utilization and prior authorization requirements.
This executive summary prepares clinicians, coders, and policy professionals to understand how CPT code 28890 is used in practice, the typical sites of service, and the facets of payer engagement that affect access and billing for extracorporeal shock wave therapy for plantar fasciitis.
Billing Code Overview
CPT code 28890 describes the administration of high-energy sound waves to the sole of the foot to stimulate healing of the plantar fascia, the thick band of connective tissue that supports the foot arch. Ultrasound guidance is used as a directional aid during the procedure. The description specifies that the procedure is performed with the patient under regional or general anesthesia due to the painful nature of treatment.
Service Type: Extracorporeal shock wave therapy for plantar fasciitis
Typical Site of Service: Hospital outpatient department or ambulatory surgery center

Clinical & Coding Specifications
Clinical Context
A 46-year-old recreational runner with a 12-month history of chronic plantar fasciitis presents after failure of conservative care including rest, orthotics, physical therapy, night splints, NSAIDs, and corticosteroid injection. Pain is localized to the medial plantar heel and is worse with first steps in the morning and prolonged weight-bearing. Imaging (ultrasound or MRI) confirms thickened plantar fascia without partial tear.
The provider performs high-energy extracorporeal shock wave therapy to the sole of the foot (28890) using ultrasound guidance as a directional aid. Because the procedure is painful, the patient receives regional or general anesthesia per preoperative planning. The clinical workflow includes pre-procedure consent and anesthesia evaluation, sterile prep of the plantar surface, ultrasound localization of the targeted plantar fascia segment, delivery of shock waves to the identified focus, post-procedure recovery while anesthesia wears off, discharge instructions for modified weight-bearing and follow-up at 2–6 weeks to assess pain and function, and documentation of device settings and waveform count in the operative note.
