ICD-10 code for mental health status evaluation

The ICD-10-CM code for mental health status evaluation is Z00.8 (Encounter for other general examination). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z00.8.

Within Z00, choose Z00.8 (other general examination) only when documentation doesn't support a more specific option: general adult medical examination (Z00.0), newborn, infant and child health examinations (Z00.1), examination for period of rapid growth in childhood (Z00.2), examination for adolescent development state (Z00.3), examination of potential donor of organ and tissue (Z00.5), examination for normal comparison and control in clinical research program (Z00.6) and examination for period of delayed growth in childhood (Z00.7).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
