HCPCS G0329: Electromagnetic Therapy for Chronic Ulcers
HCPCS Level II code G0329 represents electromagnetic therapy for chronic, nonhealing stage III and IV pressure ulcers and other complex lower-extremity ulcers. The code covers delivery of electromagnetic modalities as part of a formal therapy plan of care when wounds have not demonstrated measurable healing after 30 days of conventional care. Nationally, use of targeted adjunctive wound therapies such as electromagnetic therapy is relevant to providers and payers focused on reducing chronic wound morbidity, preventing complications, and managing costs associated with prolonged wound treatment.
Key payers discussed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise policy and clinical context for the code, expected sites of service, common clinical diagnoses that align with the code, and related procedure codes commonly billed in wound care episodes. The publication outlines typical care scenarios where G0329 applies, summarizes related services such as debridement and electrical stimulation, and highlights billing considerations and common modifiers in practice.
This resource serves clinicians, revenue cycle staff, and policy analysts seeking a national overview of HCPCS Level II code G0329, its clinical indications, and how it fits within wound-care service lines and reimbursement workflows.

UnitedHealth Group and BUCA have intermediate spreads of $10.6 and $8.2 respectively, while Aetna is the tightest with an IQR of $3.0, indicating more consistent negotiated rates. These differences signal where pricing is most concentrated versus most variable among payers.
