About coding depression screening
The ICD-10-CM code for depression screening is Z13.31 (Encounter for screening for depression). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z13.31.
Within Z13.3 (encounter for screening examination for mental health and behavioral disorders), Z13.31 is specifically for encounter for screening for depression. Related codes cover unspecified (Z13.30), 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.
