Within Z13 (encounter for screening for other diseases and disorders), Z13.0 is specifically for encounter for screening for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism. Related codes cover screening for diabetes mellitus (Z13.1), screening for nutritional, metabolic and other endocrine disorders (Z13.2), screening examination for mental health and behavioral disorders (Z13.3), screening for certain developmental disorders in childhood (Z13.4), screening for eye and ear disorders (Z13.5), screening for cardiovascular disorders (Z13.6), screening for genetic and chromosomal anomalies (Z13.7), screening for other specified diseases and disorders (Z13.8) and 1 more.
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.
