MA66 Remark Code - Missing/Invalid Procedure Code
The MA66 remark code indicates that the claim has a missing, incomplete, or invalid principal procedure code. This remark supplements the accompanying reason code by providing specific insight into the nature of the coding issue affecting the claim.
How It Relates to the Denial
