Denial-Proof Molecular Infectious Disease Panel Coding Cheat Sheet

Description

Multiplex molecular testing panels have become a cornerstone of modern infectious disease diagnostics.

However, these services also present significant compliance risks. Because many panels test for multiple pathogens simultaneously, coding errors such as unbundling individual pathogen tests or selecting the wrong CPT code can quickly result in claim denials.

This Infectious Disease Panel Coding Guide breaks down how molecular diagnostic tests are evaluated by payers and auditors.

Inside the guide you will learn:

✔ How to correctly report multiplex infectious disease panels (87631–87636)
✔ When individual pathogen codes such as 87798 are appropriate
✔ When to report unlisted molecular pathology codes (81479)
✔ Coding rules for COVID molecular testing such as U0005
✔ How specimen methodology determines correct coding
✔ Common unbundling errors and audit triggers
✔ Documentation standards that support medical necessity
✔ A step-by-step auditor-style claim review process

Rather than memorizing individual coding rules, this guide helps coders understand the logic used by payers when reviewing molecular infectious disease claims.

The result is cleaner claims, fewer denials, and stronger documentation support.
