Genicular artery embolization

Genicular artery embolization is a minimally invasive procedure that blocks blood flow to the genicular arteries in the knee to reduce osteoarthritis pain. Most major US insurers, including UnitedHealthcare and Aetna, classify genicular artery embolization as investigational or experimental for knee osteoarthritis as of 2024.

Medicare does not cover genicular artery embolization for knee pain because it lacks sufficient long-term efficacy data, the Insurance Information Database confirms. Out-of-pocket costs for uninsured patients can range from $7,000 to $12,000 per procedure according to published hospital pricing reports.

Insurers typically require documented failure of conservative treatments such as physical therapy and corticosteroid injections before considering coverage requests for genicular artery embolization. CPT code 37243 most commonly applies to this procedure when submitting insurance claims in the US.

Blue Cross Blue Shield’s medical policy states that clinical trials have not yet established durable benefits over standard therapies like total knee replacement or radiofrequency ablation. Appeals for denied claims may succeed if submitted with supporting peer-reviewed studies showing significant reduction in WOMAC pain scores after genicular artery embolization compared to baseline at six months post-procedure (e.g.

Bagla et al. Radiology 2021).
