About coding Lives in a homeless encampment
The ICD-10-CM code for Lives in a homeless encampment is Z59.02 (Unsheltered homelessness).
Within Z59.0 (homelessness), Z59.02 is specifically for Unsheltered homelessness. Related codes cover unspecified (Z59.00) and Sheltered homelessness (Z59.01).
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.
