Summary & Overview
CPT 91113: Colon Capsule Endoscopy Imaging and Interpretation
CPT code 91113 covers capsule endoscopy imaging of the colon: a noninvasive diagnostic procedure in which a patient swallows a camera-fitted capsule that captures images as it passes through the gastrointestinal tract, followed by a clinician’s interpretation and report. This code represents an evolving modality for visualizing intraluminal colonic pathology without conventional colonoscopy and matters nationally as payers, clinicians, and imaging providers incorporate capsule technologies into diagnostic pathways and coverage policies.
Key national payers included in the discussion are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for colon capsule imaging, common billing considerations tied to image interpretation and reporting, and where to expect policy attention as capsule technologies diffuse. The publication also summarizes typical sites of service and service type for operational planning.
The report provides benchmarks and policy-focused content relevant to coding and payer coverage trends, clarifies what CPT code 91113 denotes clinically, and identifies areas where payers may define medical necessity or prior authorization approaches. Data not available in the input is noted where applicable; the focus remains on national implications for clinicians, billing staff, and policy stakeholders considering adoption or reimbursement of colon capsule endoscopy imaging.
Billing Code Overview
CPT code 91113 describes a diagnostic procedure in which imaging is obtained from inside the colon using an ingestible capsule fitted with a camera. As the capsule traverses the gastrointestinal tract, it captures sequential images of the colon, which the provider later reviews, interprets, and reports to detect or diagnose abnormalities.
-
Service type: Diagnostic gastrointestinal capsule endoscopy imaging with image interpretation and reporting
-
Typical site of service: Ambulatory clinic, outpatient imaging center, or other noninpatient settings where capsule ingestion and image retrieval occur
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with intermittent rectal bleeding and unexplained iron-deficiency anemia is referred to a gastroenterology practice for evaluation of the colon. The patient previously had an incomplete optical colonoscopy due to difficult anatomy and comorbid cardiopulmonary disease that increases procedural risk. After discussion of diagnostic options, the provider orders a colon capsule endoscopy. The patient swallows an ingestible video capsule in an outpatient endoscopy suite or ambulatory clinic; external sensors record images as the capsule traverses the gastrointestinal tract. The practice provides pre-procedure instructions, verifies the indication and consent, and confirms bowel preparation adequacy. After the study period, the provider downloads and reviews the captured images, interprets findings (such as polyps, vascular lesions, or sources of bleeding), documents the report, and communicates results to the referring clinician and patient. Typical sites of service include an outpatient endoscopy suite, ambulatory clinic, or hospital outpatient department when medical comorbidities or monitoring needs require these settings.
