About coding Surroundings unsatisfactory
The ICD-10-CM code for Surroundings unsatisfactory is Z59.19 (Other inadequate housing). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z59.19.
Within Z59.1, choose Z59.19 (Other inadequate housing) only when documentation doesn't support a more specific option: unspecified (Z59.10), environmental temperature (Z59.11) and utilities (Z59.12).
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.
