Why Outsourcing Your Gastroenterology Billing Is the Key to Higher Revenue and Lower Stress.

Gastroenterology billing is one of the most complex in all of outpatient specialty care. From diagnostic and therapeutic endoscopy, to screening colonoscopies, ERCPs, capsule endoscopy, and in-office procedures, GI practices bill a wide range of services—each with its own coding rules, modifiers, and payer-specific nuances. For providers offering gastroenterology in Phoenix, the challenges are even greater due to payer-specific policy variations.

One misused modifier can turn a reimbursable colonoscopy into a denied claim. Incomplete documentation can delay payment on high-value procedures like EUS or liver biopsies. On top of that, insurance carriers frequently change their policies, especially for screening vs. diagnostic procedures, making it increasingly difficult for in-house teams to stay ahead.

Many GI practices struggle with:

  • High denial rates due to incorrect bundling or modifier errors
  • Underpayments for high-complexity procedures
  • Staff burnout from managing complex billing requirements
  • Revenue leakage due to missed coding opportunities
  • Delays in payments that hurt cash flow and stall growth

That’s why more forward-thinking gastroenterologists are choosing to outsource their billing to a specialized partner who knows the GI revenue cycle inside and out.
