Gastroenterology billing crosses several workflows that are easy to manage separately and difficult to reconcile later: office visits, endoscopic procedures, anesthesia coordination, pathology, infusions and specialty medications.
A billing partner should fit within the practice’s practice management process, not operate as an isolated claim-submission department.
Follow one case from scheduling through payment
During vendor evaluation, walk through a common procedure from benefit verification and authorization to documentation, coding, claim response and patient balance. The exercise shows where responsibilities change hands.
A GI group expanding its infusion schedule
A practice adds infusion capacity while its procedure volume remains stable. The billing vendor understands professional claims but the new drug workflow requires benefit checks, authorization tracking, charge reconciliation and inventory-related documentation. The contract needs to address that service line explicitly.
Specialty experience should be tested through actual workflows. A vendor may be a good fit for procedures and need a deliberate implementation plan for infusion billing.

Coordinate procedure scheduling and authorization
Case changes should trigger a documented check rather than rely on memory.
Reconcile documentation and charges
Completed procedures, supplies and administered drugs need a consistent charge-handoff process.
Define pathology coordination
Clarify which entity bills pathology and how orders, results and patient responsibility are communicated.
Track specialty-drug exceptions
Separate authorization, dosage, coding and payer-policy issues so root causes are visible.
Review denials at service-line level
Office, procedure and infusion denials should not disappear into one overall percentage.
Questions worth asking before you choose
- Which GI workflows has the proposed team supported?
- How are changed procedures rechecked for authorization?
- How are administered drugs reconciled to charges?
- Can reporting separate office, procedure and infusion A/R?
- How are documentation questions returned to providers?
What a useful proposal should make clear
A serious medical billing proposal should define responsibility for eligibility, coding review, charge entry, claim submission, rejections, denials, payment posting, patient balances, reporting and account follow-up. It should also explain software, interfaces, implementation, data ownership, contract terms and how unresolved work is escalated. Compare that operating scope before comparing a percentage or monthly fee.
A practical next step
Compare specialty scope through the medical billing company request before assuming every GI service is included.
Frequently asked questions
Is gastroenterology billing only procedure coding?
No. Eligibility, authorization, documentation, office services, pathology and follow-up are all part of the workflow.
Should infusion billing be evaluated separately?
Yes. It adds benefit, authorization, drug and reconciliation requirements.
What reporting is useful for a GI practice?
Service-line A/R, denials by cause, unresolved documentation and payer response trends are practical starting points.
