CPT code 49521 represents the surgical repair of a recurrent inguinal hernia that is incarcerated or strangulated. Nationally, this code captures urgent or emergent hernia repairs where prior repair has failed and the hernia is trapped or its blood supply is compromised, conditions associated with increased clinical risk and potential for complications.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage and payment for this procedure can vary by payer and by site of service; commercial plans and Medicare typically distinguish between elective hernia repairs and urgent repairs for incarceration or strangulation.

Readers will get a concise clinical and billing overview of CPT code 49521, including the clinical context that necessitates this procedure, typical sites of service, and the payers commonly involved in national analyses. The publication outlines benchmarks and policy-relevant considerations that affect billing and coverage for urgent hernia repairs, summarizes common modifiers associated with surgical services, and provides context for how recurrent, incarcerated or strangulated presentations differ from elective hernia repair in coding and clinical urgency.
