What Medicare edits apply to D47.Z1?
The Medicare Code Editor screens inpatient claims before they are grouped. These edits name D47.Z1 directly.
CMS will reject this code as the principal diagnosis on an inpatient claim. It describes something other than the condition chiefly responsible for the admission.
Which MS-DRGs does D47.Z1 group to?
D47.Z1 sits in MDC 21 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
