🔬 The Challenge

The Gastroenterology
Billing Challenge

Gastroenterology billing involves complex anesthesia crossover rules for endoscopy procedures, where both the gastroenterologist and anesthesiologist must bill correctly to avoid duplicate payment denials. Colonoscopy add-on codes for polyp removal require precise sequencing. Screening vs. diagnostic colonoscopy designation changes reimbursement significantly, and modifier misapplication is the leading cause of GI claim denials.

Our Approach

What REL1EF Does Differently

Anesthesia crossover accuracy for endoscopy procedures
Colonoscopy add-on code sequencing optimization
Screening vs. diagnostic designation for maximum reimbursement
OON Upside

The OON Opportunity
in Gastroenterology

GI groups performing procedures at multiple facilities frequently encounter OON patients. REL1EF negotiates up to 6× Medicare on endoscopy and colonoscopy procedures — the same procedures that payer vendors routinely reprice to a fraction of billed charges.

Billing Questions

Common questions about GI billing, anesthesia crossover, and colonoscopy coding.

When a gastroenterologist performs an endoscopy with anesthesia support, both the GI physician and anesthesiologist submit claims for the same encounter. Crossover rules require precise modifier application and code coordination to prevent duplicate payment denials. REL1EF manages the crossover process to ensure both claims are paid without triggering payer edits.
Screening colonoscopies are preventive and often covered at 100% with no patient cost-sharing, while diagnostic colonoscopies are performed to evaluate symptoms or findings and are subject to deductibles and copays. The designation changes reimbursement significantly — a screening that converts to diagnostic mid-procedure requires specific modifier application to maximize reimbursement. REL1EF ensures correct designation on every claim.
Gastroenterology procedures frequently involve add-on codes for polyp removal, biopsy, and additional interventions performed during the same session. These codes must be sequenced correctly with the primary procedure, and incorrect ordering triggers automatic denials. REL1EF's GI-trained coders ensure precise sequencing and modifier application on every claim.
