CPT code 91112 denotes a diagnostic gastrointestinal motility study performed with a wireless capsule imaging device that measures transit time and pressure/strength of muscle contractions in the stomach and colon, with provider interpretation and reporting. Nationally, this code captures an advanced, minimally invasive physiologic test used to evaluate suspected gastroparesis, chronic constipation, and other motility disorders when direct manometry or traditional transit studies are not suitable. Its use affects clinical pathways for digestive disorders and enters payer coverage discussions because of device costs and the need for specialist interpretation.

Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical purpose and typical care setting for the service, followed by benchmarking information, payer coverage patterns, and relevant policy considerations where available. The publication outlines how the service is billed, common modifier usage, and practical claims considerations that influence reimbursement and utilization. Data not available in the input is identified explicitly where applicable. The content is intended to support coding, billing, and policy review for clinicians, revenue cycle staff, and payers evaluating use of wireless capsule-based gastric and colonic motility studies.
