About Z13.30
Z13.30 is the ICD-10-CM diagnosis code for encounter for screening examination for mental health and behavioral disorders, unspecified. It belongs to category Z13 (encounter for screening for other diseases and disorders), block Z00-Z13 (persons encountering health services for examinations) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
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.
It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It was added in FY2019, effective October 1, 2018.
