About coding administrative purpose only encounter
The ICD-10-CM code for administrative purpose only encounter is Z02.9 (Encounter for administrative examinations, unspecified). The official index lists 13 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z02.9.
Within Z02, choose Z02.9 (s, unspecified) only when documentation doesn't support a more specific option: examination for admission to educational institution (Z02.0), pre-employment examination (Z02.1), examination for admission to residential institution (Z02.2), examination for recruitment to armed forces (Z02.3), examination for driving license (Z02.4), examination for participation in sport (Z02.5), examination for insurance purposes (Z02.6), issue of medical certificate (Z02.7) 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.
