Gastroenterology Medical Billing Services

Gastroenterology billing is procedurally complex. One wrong colonoscopy modifier, one missed polyp removal code, or one bundled procedure—and thousands in revenue vanish.

Neo MD fixes that with gastroenterology-certified coders, endoscopy-specific coding workflows, and aggressive procedure capture built for GI complexity.

Why General Medical Billing Companies Fail Gastroenterology Practices

Gastroenterology billing requires specialty expertise that general billers don’t have.

Screening vs diagnostic chaos

Don't apply PT modifier when findings change status

Polyp technique blindspot

Can't distinguish hot biopsy, snare, EMR codes

Multiple polyp confusion

Don't count and code separate polyp removals

EGD biopsy miss

Bundle biopsies that should bill separately

Biologic infusion errors

Miscalculate drug units and wastage

Medical necessity gaps

Can't document repeat endoscopy justification

Hemorrhoid procedure underbilling

Don't capture multiple band placements

Anesthesia modifier mistakes

Don't coordinate with anesthesia billing

Result: 15%–22% denial rates, 45-60 day payment cycles, and constant staff time wasted on resubmissions.

Our Process: Our 90-Day Revenue Acceleration Process

Step 1 (Week 1)
Free 90-Day Revenue Diagnostic

We begin with a comprehensive analysis of your last 90 days of billing data, examining every colonoscopy procedure for multiple polyp coding accuracy, screening versus diagnostic classification, and PT modifier application. Our team reviews ERCP procedures for component billing optimization, evaluates EGD coding for biopsy site documentation, and assesses infusion therapy revenue capture opportunities. You receive a detailed report showing exactly where revenue is leaking with specific examples of undercoded procedures and the dollar amount being lost to each type of coding error or missed service opportunity.

Step 2 (Weeks 2-3)
Seamless Transition

 Our implementation team coordinates a smooth transition with zero disruption to your endoscopy schedule or patient care. We integrate with your EMR and endoscopy reporting system (whether you're using Provation, Pentax, EndoWorks, Epic, or any other platform), verify all payer enrollments and credentialing including ASC facility contracts, set up endoscopy-specific coding protocols with automatic polyp count capture, establish screening versus diagnostic determination workflows, and provide comprehensive training to your physicians, endoscopy nurses, and billing staff on documentation requirements for multiple polyps, ERCP components, and infusion therapy billing. Most practices have their first clean claims submitted within 10-12 business days.

Step 3 (Days 30-90)
Revenue Acceleration

This is where you see immediate financial impact. Our certified gastroenterology coders begin capturing every additional polyp removal code on multi-polyp colonoscopies, implementing correct ERCP component billing for sphincterotomy, stent, and stone extraction procedures, optimizing screening to diagnostic conversions with proper PT modifier application, and launching or optimizing infusion therapy billing for IBD patients with complete drug supply and administration coding. We systematically rework and resubmit old denied claims with corrected coding and enhanced procedure documentation. Within the first 30 days, most practices see noticeable cash flow improvement from multiple polyp optimization alone, and by day 90, our clients average a 27-32% revenue increase without adding endoscopy time slots or performing more procedures.

Step 4 (Ongoing)
Continuous Optimization

Revenue optimization doesn't stop at 90 days. We provide bi-weekly updates on colonoscopy screening guideline changes and payer policy modifications, conduct monthly endoscopy coding reviews with your providers to ensure continued documentation accuracy for polyp size and location, perform quarterly compliance audits on screening versus diagnostic classifications and ERCP component coding, and deliver annual CPT code update training specific to gastroenterology and endoscopy services. As your practice adds new procedures like endoscopic mucosal resection, radiofrequency ablation, or new biologic infusions, we proactively research coverage policies and implement billing protocols to ensure maximum reimbursement from day one.

The Cost of Waiting

If you’re a gastroenterology practice collecting $4.2M annually and losing 29% to billing inefficiencies:

$1,218,000

Annual revenue loss

$6.09 million

5-year total loss

That’s hiring another gastroenterologist, opening your own ASC, investing in advanced endoscopy equipment like EUS or confocal imaging, or launching comprehensive IBD infusion services.

Every month you wait costs you $101,500 you'll never recover.

The question isn’t “Should I switch?”
The question is: “How much more am I willing to lose?”
