About coding cystostomy status
The ICD-10-CM code for cystostomy status is Z93.50 (Unspecified cystostomy status). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z93.50.
Within Z93.5, choose Z93.50 (Unspecified cystostomy status) only when documentation doesn't support a more specific option: Cutaneous-vesicostomy status (Z93.51), Appendico-vesicostomy status (Z93.52) and other cystostomy status (Z93.59).
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.
