FAQ: Navigating Gastroenterology Billing Guidelines
Gastroenterology billing guidelines are a set of payer-specific and regulatory rules that govern how gastroenterology services should be coded, documented, and billed for proper reimbursement. These guidelines ensure compliance with Medicare, Medicaid, and commercial insurer requirements and help avoid claim denials, audits, and financial penalties.
