Nineteen gastrointestinal diagnostic codes, spanning esophageal motility studies, capsule endoscopies and breath tests, have been added to the ASC-covered services list, a move that could expand access to specialized GI testing in outpatient settings and reshape how facilities bill for these procedures.
Here are the 19 procedures:
| CPT | Description |
| 91010 | Esophageal motility (manometric) study with interpretation |
| 91020 | Gastric motility (manometric) study |
| 91022 | Duodenal motility (manometric) study |
| 91030 | Esophageal acid perfusion (Bernstein) test for esophagitis |
| 91034 | Esophageal gastroesophageal reflux test – nasal catheter pH electrode(s) |
| 91037 | Esophageal function test – gastroesophageal reflux with nasal catheter intraluminal impedance |
| 91038 | Esophageal function test – gastroesophageal reflux with impedance, prolonged (up to 24 hours) |
| 91040 | Esophageal balloon distension study with provocation |
| 91065 | Breath hydrogen or methane test (e.g., for lactase deficiency, bacterial overgrowth) |
| 91110 | Capsule endoscopy – esophagus through ileum |
| 91111 | Capsule endoscopy – esophagus only |
| 91112 | Gastrointestinal transit and pressure measurement – stomach through colon, wireless capsule |
| 91113 | Capsule endoscopy – colon |
| 91117 | Colon motility (manometric) study – minimum 6 hours continuous recording |
| 91124 | Rectal sensation, tone, and compliance study (e.g., barostat) |
| 91125 | Anorectal manometry with rectal sensation and rectal balloon expulsion test |
| 0977T | Upper GI blood detection – sensor capsule with interpretation |
| 9779 | Endoscopic submucosal dissection |
| 9901 | Endoscopic defect closure throughout the gastrointestinal tract |
At the Becker's 23rd Annual Spine, Orthopedic and Pain Management-Driven ASC + The Future of Spine Conference, taking place June 11-13 in Chicago, spine surgeons, orthopedic leaders and ASC executives will come together to explore minimally invasive techniques, ASC growth strategies and innovations shaping the future of outpatient spine care.
