Gastroenterology billing & credentialing
Screening vs diagnostic colonoscopy is where GI revenue leaks: modifier 33, PT and sedation rules decide whether you’re paid. We get every scope coded right.

Why gastroenterology is different
In GI, a screening colonoscopy that finds and removes a polyp becomes a diagnostic procedure, and without modifier 33 or PT the patient gets a surprise bill and you get a denial.
We code colonoscopies and EGDs to screening vs diagnostic rules, apply modifier 33 and PT when a screening turns therapeutic, bill moderate sedation correctly, handle ERCP and advanced procedures, and split pathology components.

Credentialing for gastroenterology
GI enrollment usually spans your office, an endoscopy suite or ASC, and hospital privileges. We manage all three.
- Medicare (PECOS) & Medicaid enrollment for every provider
- Commercial payer paneling matched to your patient mix
- CAQH build, attestation & ongoing maintenance
- Revalidations and re-credentialing tracked before they lapse
- ASC / endoscopy-center enrollment alongside office and hospital
- Enrollment for every gastroenterologist, PA and CRNA who bills
