Gastroenterology Billing Services
Gastroenterology Billing Services That Stop Revenue From Slipping Through
GI billing is among the most technically demanding in medicine, with modifier-sensitive endoscopy coding, NCCI bundling rules, colonoscopy screening-to-diagnostic conversions, and payer-specific LCD criteria creating constant denial risk. ProtoMed's certified gastroenterology billing specialists ensure every high-value procedure claim is coded precisely and submitted compliantly. Fewer denials. Faster reimbursements. More revenue.
98%+
Clean Claim Rate
We scrub every GI claim against payer-specific rules before submission, catching modifier errors, NCCI bundling conflicts, and screening-to-diagnostic conversion issues before they reach the payer.
Why Choose ProtoMed
Stop Losing GI Revenue to Bundling Errors and Coding Denials
Gastroenterology practices lose 12–18% of potential revenue not because of volume problems, but because of coding precision failures. A colonoscopy with polyp removal requires exact modifier application. Miss modifier 59 or XS on a separately billable component and Medicare bundles the entire claim into one underpaid procedure. A screening colonoscopy that converts to diagnostic mid-procedure must be rebilled under the correct CPT with the right modifier, or the conversion is lost entirely. These are not rare edge cases. They happen every day in every GI practice billed by a generalist team.
ProtoMed's certified gastroenterology billing specialists understand NCCI bundling edits, LCD compliance requirements, and the modifier logic behind every high-value GI procedure. We scrub every claim against payer-specific rules before submission, appeal every denial with the clinical documentation payers require, and identify the root causes of denial patterns so they stop recurring.

Gastroenterology Coding Expertise
Gastroenterology Coding Expertise That Reduces Denials
GI billing spans high-value endoscopic procedures, advanced diagnostic imaging, chronic disease management, and anesthesia coordination, each with its own modifier rules, NCCI bundling edits, and LCD documentation requirements. Our certified coders know every nuance.
Colonoscopy: diagnostic, screening, biopsy, polypectomy, and therapeutic interventions — correctly coded for procedure type, modifier, and screening-to-diagnostic conversion rules.
Upper GI endoscopy (EGD): biopsy, dilation, injection, and therapeutic add-ons unbundled correctly under NCCI edits with modifier 59 or XS applied as required.
ERCP: biliary and pancreatic procedures with primary and add-on code sequencing, prior authorization management, and complete clinical documentation for full reimbursement.
Endoscopic ultrasound (EUS): diagnostic and FNA with add-on code documentation, correct selection between diagnostic and interventional codes, and medical necessity support.
Capsule endoscopy: small bowel imaging with LCD compliance and physician interpretation billed separately, meeting all payer-specific documentation requirements for clean first-pass claims.
Moderate sedation: time-based billing for GI procedure encounters, coordinated with anesthesia to avoid duplicate claim conflicts and documentation mismatches.
GI diagnosis coding: IBD, diverticular disease, liver disease, and chronic GI conditions, coded with the specificity payers require to support medical necessity on every claim.
Specialized Services
Specialized Billing for Every GI Procedure
Each gastroenterology procedure carries distinct modifier requirements, bundling rules, and documentation standards. A single coding error on a high-value GI claim can cost hundreds of dollars per encounter. ProtoMed's certified team gets every claim right the first time.
Colonoscopy Billing
Colonoscopy billing is the highest-risk area in GI coding. Screening versus diagnostic designation, mid-procedure conversion rules, polyp removal technique documentation, and modifier PT for Medicare patients all affect reimbursement. We correctly apply every CPT code, modifier, and bundling rule for each colonoscopy encounter, including incomplete procedures and same-session interventions.
Upper GI Endoscopy (EGD) Billing
EGD claims routinely involve multiple billable components — biopsy, dilation, injection, and Barrett's ablation — that must be unbundled correctly under NCCI edits using modifier 59 or XS. We capture every separately reportable EGD component, apply the correct modifiers, and submit multi-component claims with the documentation payers require for first-pass acceptance.
ERCP Billing
ERCP is the most documentation-intensive procedure in gastroenterology. Primary and add-on codes must be sequenced correctly, prior authorization must be verified before every case, and complete clinical documentation of the biliary and pancreatic interventions performed is essential for full reimbursement. We manage every ERCP claim from pre-authorization through final payment.
Endoscopic Ultrasound (EUS) Billing
EUS billing requires correct selection between diagnostic and interventional codes, accurate use of fine needle aspiration add-on codes (CPT 43242), and full medical necessity documentation to satisfy payer LCD criteria. We ensure every EUS encounter, diagnostic or therapeutic, is coded to capture its complete reimbursement value.
Capsule Endoscopy Billing
Capsule endoscopy claims must meet strict LCD criteria for medical necessity, include separate billing for the physician interpretation component, and comply with payer-specific documentation requirements. We submit LCD-compliant capsule endoscopy claims with complete supporting clinical evidence, ensuring clean, first-pass reimbursement on every study.
Anesthesia & Pathology Coordination Billing
GI procedures involving moderate sedation or MAC anesthesia require coordinated billing between the GI and anesthesia teams to avoid duplicate claim conflicts and documentation mismatches. When biopsies are taken, pathology coordination is essential to prevent delays in professional fee capture. We manage both coordination points to keep your full procedure revenue flowing without bottlenecks.
Our Process
How ProtoMed's Gastroenterology Billing Process Works
A structured four-step process that ensures every GI procedure is coded with modifier precision, every claim is tracked, and every denial is appealed with the clinical documentation payers require.
Practice Audit & Revenue Gap Analysis
We review your current GI billing setup, identify procedure-level revenue leaks from modifier errors, NCCI bundling mistakes, and unresolved denials, then securely access your existing EHR with zero disruption to your procedure schedule or clinical operations.
Eligibility Verification & Prior Authorization
Before each procedure, we verify patient coverage, confirm payer-specific LCD criteria for advanced procedures, and manage prior authorization for ERCP, capsule endoscopy, and complex EUS cases. Catching authorization and eligibility gaps before the procedure eliminates the most preventable source of high-value GI claim denials.
Claim Coding, Scrubbing & Payer Submission
Our certified GI coders review every encounter, apply the correct CPT codes and modifiers under NCCI bundling rules, and scrub each claim against payer-specific requirements before submission. Claims are submitted electronically on time to Medicare, Medicaid, and all major commercial payers, with zero guesswork on bundling edits or modifier logic.
Denial Management, Payment Posting & Reporting
Every denied claim is appealed with clinical documentation and root-cause analysis so the same denial does not recur. Payments are posted accurately, pathology and anesthesia coordination is reconciled, and you receive clear monthly reports on collections, denial patterns, and procedure-level reimbursement performance.
