About coding deployment status
The ICD-10-CM code for deployment status is Z56.82 (Military deployment status). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z56.82.
Within Z56.8 (other problems related to employment), Z56.82 is specifically for military deployment status. Related codes cover sexual harassment on the job (Z56.81) and other problems related to employment (Z56.89).
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.
