CPT 91124: Rectal Sensation, Tone, and Compliance Study
CPT code 91124 denotes a rectal sensation, tone, and compliance study that objectively evaluates rectal sensory thresholds, muscular tone, and compliance (stretch and relaxation), often using a barostat or balloon system. Nationally, this physiologic diagnostic test is important for diagnosing defecatory disorders, fecal incontinence, and causes of chronic constipation when structural imaging is unrevealing; it informs clinical management and suitability for specialized therapies.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines payer coverage patterns, typical sites of service, and where this test fits into the diagnostic pathway for anorectal dysfunction.
Readers will learn the clinical context for ordering a rectal compliance study, how the service is performed, benchmark considerations for utilization and site-of-service, and common coding and billing considerations. The report highlights national policy and coverage trends, typical clinical indications, and operational implications for facilities that perform anorectal physiologic testing.
