About coding Migrant social
The ICD-10-CM code for Migrant social is Z59.00 (Homelessness unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z59.00.
Within Z59.0, choose Z59.00 (unspecified) only when documentation doesn't support a more specific option: Sheltered homelessness (Z59.01) and Unsheltered homelessness (Z59.02).
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.
