About coding Sheltered homelessness
The ICD-10-CM code for Sheltered homelessness is Z59.01 (Sheltered homelessness).
Within Z59.0 (homelessness), Z59.01 is specifically for Sheltered homelessness. Related codes cover unspecified (Z59.00) 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.
