The challenge
Why Gastroenterology Practices Need Specialized Billing
The defining problem in GI billing is intent. A screening colonoscopy that becomes diagnostic is still a screening for benefit purposes under most plans, and modifier 33 or PT is applied so the patient keeps that benefit instead of receiving an unexpected bill. Intent at scheduling and findings at the procedure are reviewed together, not separately.
Procedure coding follows the note, including technique, findings and specimen count, and pathology is checked against the procedure claim so the same work is never billed twice. Anesthesia claims are reconciled against the same case record before either side is submitted, whether anesthesia is billed by your own group or by a third party.
We help gastroenterology practices separate screening from diagnostic intent, keep procedure coding compliant, and follow every claim through payment. The result is a clearer workflow and fewer avoidable rejections.
Screening versus diagnostic scopes
The same procedure bills differently depending on intent and findings, and getting it wrong bills a patient for care that should have been covered in full.
Modifier-driven reimbursement
Modifiers 33, PT and 59 change both payment and patient responsibility on endoscopy claims, and payers apply them inconsistently.
Facility and professional splits
Procedures performed in an ASC or hospital require coordinated professional and facility billing that is easy to drop.
Anesthesia coordination
Monitored anesthesia billing alongside endoscopy follows separate rules that vary by payer and by patient risk status.
Pathology and specimen billing
Specimens sent out generate claims that must reconcile against the procedure, or revenue is simply never captured.
Surveillance interval rules
Payers enforce frequency limits on surveillance colonoscopy that deny claims when intervals are not tracked per patient.
What Makes Our Gastroenterology Billing Services Different
Our gastroenterology billing is not general medical billing adapted after the fact. It is built around the coding rules, payer behaviour and documentation standards specific to this specialty.

Core Components of Our Gastroenterology Billing Services
Our revenue cycle model covers every stage — from eligibility verification before the first claim is created, through payment reconciliation and A/R resolution after adjudication.
-
01
Patient eligibility and benefits verification
Coverage is verified before the first claim is created, which removes the largest single category of preventable front-end denial.
- Correct patient demographics
- Active insurance verification
- Benefit and coverage confirmation
- Referral and authorization requirements
- Secondary insurance coordination
-
02
Charge entry and coding accuracy
Every visit and procedure is reviewed for accuracy before charge entry, because accurate coding protects both revenue and compliance.
- Correct CPT and ICD-10 selection
- Appropriate modifier application
- Documentation support and review
- Timely charge entry workflows
-
03
Electronic claims submission
Claims are transmitted electronically to reduce turnaround time and improve first-pass acceptance, then monitored until they are fully adjudicated.
- Payer-specific claim edits
- Clearinghouse acceptance confirmation
- Rejection resolution within 24 hours
- Submission tracking to adjudication
-
04
Payment posting and reconciliation
Payments are reconciled against expected contractual adjustments, so discrepancies are tracked and recovered rather than absorbed.
- Remittance posting against the original charge
- Contractual adjustment validation
- Underpayment identification
- Patient balance accuracy
-
05
Accounts receivable follow-up
Unresolved A/R is revenue leakage. We follow strict timelines to keep claims actively moving through payer workflows.
- Active A/R management by aging bucket
- Payer workflow follow-up and escalation
- Appeals when required
- Prompt resolution tracking
-
06
Claims processing and reporting
Performance dashboards give practice leaders clear visibility — not generic billing spreadsheets.
- Claim acceptance rates
- Specialty-specific denial trends
- Days in A/R by payer
- Revenue metrics over time

Gastroenterology Billing — Common Questions
Answers to the revenue cycle questions gastroenterology practices ask most often.
How do you handle screening that becomes diagnostic?
Intent at scheduling and findings at the procedure are reviewed together, and modifier 33 or PT is applied so the patient keeps the screening benefit where the rules allow.
Do you bill the ASC as well as the physician side?
Yes. Facility and professional claims for the same case are billed and reconciled together, which prevents both duplication and missed charges.
Is anesthesia billing included?
We coordinate anesthesia claims against the endoscopy record so the two agree, whether anesthesia is billed by your group or a third party.
How are biologic infusions handled?
Authorization is obtained ahead of scheduling, and drug units and wastage are reported precisely on the claim.
