About coding noncompliance with dialysis
The ICD-10-CM code for noncompliance with dialysis is Z91.158 (Patient's noncompliance with renal dialysis for other reason). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z91.158.
Within Z91.15, choose Z91.158 (for other reason) only when documentation doesn't support a more specific option: due to financial hardship (Z91.151).
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.
