Will the MAO-004 report reflect diagnosis codes that are not risk adjustment eligible with a disallowed flag?
Yes, the MAO-004 report will indicate diagnoses that do not pass the CMS filtering logic with a “D”, in the allowed/disallowed flag field, meaning the diagnoses were reported but are disallowed for risk adjustment. The allowed/disallowed flag field is included to help MAOs or other entities determine which records accepted on the MAO-002 report passed the CMS filtering logic as reported on the MAO-004 report
