CodeMap Compliance Briefing: 6/06/03: Diagnosis Coding Rules

Editor's Welcome:

We continue to receive many questions concerning the appropriate use of diagnosis codes. In particular, many subscribers ask how they should determine which ICD-9 code(s) should be reported with claims for services performed for Medicare and Medicaid beneficiaries. To assist our subscribers, we are revisiting the issues presented in two CodeMap Compliance Briefings originally published in June of 2003. This week's briefing will discuss diagnosis coding rules for radiologists and pathologists. Next week, we will review diagnosis coding rules for clinical laboratories. As you will see, the rules differ depending on the type of provider. As always, please do not hesitate to forward questions, comments, or suggestions for future CodeMap Compliance Briefings.  

Sincerely,

Gregory Root, Esq.

Background

Most of the rules and accompanying examples discussed in this briefing may be found in CMS Program Memorandum Transmittal AB-01-144 ....
