The Gastroenterology Billing Challenge
Every specialty has coding landmines. Here are the ones costing gastroenterology practices the most.
Colonoscopy Variant Coding
$50-90K/yr45378-45398
Colonoscopy codes differ based on screening vs diagnostic, technique used, and findings. Billing a screening colonoscopy code when a polyp is found and removed changes the entire claim — and most practices get this wrong.
Polyp Removal Bundling
$30-60K/yr45384 / 45385 / 45388 / Modifier -59
Multiple polyp removal techniques in the same session require correct modifier-59 unbundling. Failing to separate snare polypectomy from hot biopsy or cold forceps leaves significant revenue on the table.
EGD with Biopsy Complexity
$20-35K denials43239 / 43249
Upper endoscopy with biopsy, dilation, or foreign body removal each have distinct codes. Using the base EGD code when a higher-level procedure was performed is one of the most common GI billing errors.
Pathology Coordination
15-20% path revenue lost88305 / 88312
GI practices with in-house pathology frequently lose 15-20% of pathology revenue to missed specimen billing, incorrect specimen counts, or failure to bill special stains and immunohistochemistry.
Capsule Endoscopy
High denial without auth91110 / 91111
Capsule endoscopy requires prior authorization from most payers and has strict medical necessity documentation requirements. Without proper auth and documentation, these high-dollar claims are denied on first pass.
Hemorrhoid & Ablation Procedures
Undercoded 25%+46221 / 43229
Hemorrhoid banding, ligation, and esophageal ablation procedures are undercoded in over 25% of GI practices due to incorrect technique-based code selection and missing modifier applications.

“I highly recommend Everest A/R Management to anyone looking for a Revenue Cycle Management solution. Their team was able to dive into the mess that a previous billing company had left us in and they methodically worked through the problems and even captured what we had considered to be lost revenue. They work tirelessly through denials and appeals to make sure that we get paid for the work we’ve done. Our A/R is now accurate, and our cash flow has improved significantly. We no longer stress about our billing, and we can trust them to the point where we can focus on improving other areas of the business. Their communication is excellent, and they’ve integrated so well with our team that it feels like they are a department within our organization. We couldn’t have done it without them. Thank you to everyone on the Everest team!”
