Gastroenterology Credentialing and Enrollment

Gastroenterologists split their time between clinic and procedures such as endoscopy and colonoscopy, performed in hospitals and ambulatory endoscopy centers. Many groups own or invest in an ASC, work with anesthesia providers, and run pathology arrangements. Medicare is a large part of most GI payer mixes.

Here is what credentialing involves for gastroenterology and how Maverick handles it.

Board certification

Gastroenterologists complete internal medicine residency and a GI fellowship. Gastroenterology is a subspecialty certification of the American Board of Internal Medicine (ABIM), and osteopathic gastroenterologists may certify through the American Osteopathic Board of Internal Medicine (AOBIM). Payers and facilities verify status with the board.

Privileges for procedures

Each hospital and endoscopy center grants procedural privileges through its own medical staff process. Facilities may ask for case logs or proctoring for newer physicians. Payers ask where you hold privileges, so privileges and enrollment should be coordinated rather than handled one after the other.

Surgery centers and facility enrollment

An ASC enrolls with Medicare on the CMS-855B and needs its own commercial contracts, separate from the physicians who use it. Anesthesia providers working in the center have their own enrollments too. Our surgery center page covers the facility side, and our CMS-855 form guide explains the forms.

Medicare

Gastroenterologists enroll on the CMS-855I and reassign benefits to the group. Every location, including each facility where the group bills professional services, should be reflected correctly. Our Medicare enrollment service handles initial enrollment and revalidation.

Pathology arrangements deserve a mention too. Biopsies taken during procedures are read by a pathology group or an in-house lab, and each of those has its own enrollment and billing setup. When a GI group brings pathology in-house or changes labs, the enrollment details need to follow, or claims for the pathology work stall even though the procedures themselves are paid.

Where files usually get stuck

None of these are unusual. They are the small inconsistencies that pile up when a practice is busy seeing patients:

• Physicians performing procedures at a new center before privileges and payer details are updated
• The ASC itself missing commercial contracts the physicians already have
• Anesthesia providers in the center without their own enrollments
• Reassignments not updated as physicians join or leave
• Locations missing from Medicare enrollment

What to send us

We send a tailored checklist at kickoff, but most gastroenterology files start with the same core documents. Having them ready is the single biggest thing you can do to keep your file moving:

• State license(s) for every state where you see patients
• Board certificate or documentation of board eligibility
• Medical school, residency and fellowship details
• DEA and any state controlled substance registrations
• Current malpractice certificate and claims history
• Hospital or surgery center privileges, or your admitting arrangement
• Practice locations, tax ID details and banking information for payments
• CAQH and PECOS logins, or permission for us to set them up

Texas and multi-state practices

We are based in Austin and work Texas files every day, from TMHP and Texas Medicaid managed care to the commercial plans that dominate each metro area. We also work with practices in all 50 states. If your clinicians are licensed in more than one state, or you are expanding, we map the licensing, Medicare and payer work for each state before anything is filed so nothing is missed.

How Maverick helps

We start with a records check: licenses, board status, NPPES, CAQH, existing Medicare and Medicaid enrollments, and any privileges already in place. Then we build the payer list that fits your market, prepare every application, and submit once your file is complete. We follow up with payers, facilities and the Medicare contractor on a set schedule, answer their requests for more information and keep you updated until each file closes. Afterward, re-credentialing, revalidation and CAQH re-attestation go on our calendar instead of yours.

What we will not do is promise a payer's approval date. Payers and agencies set their own processing times. What we control is a complete file, fast responses and steady follow-up.

Which package fits

Maverick Launch (Group) fits GI groups onboarding physicians or opening a center, with facility and physician enrollment coordinated. Autopilot keeps privileges, re-credentialing and revalidations current. Rate Check helps established groups review commercial contracts for both professional and facility services.
