ICD-10 code for behavioral disorder screening

The ICD-10-CM code for behavioral disorder screening is Z13.30 (Encounter for screening examination for mental health and behavioral disorders, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z13.30.

Within Z13.3, choose Z13.30 (unspecified) only when documentation doesn't support a more specific option: for depression (Z13.31), for maternal depression (Z13.32) and examination for other mental health and behavioral disorders (Z13.39).

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.
