About coding Enterobacterales carrier of
The ICD-10-CM code for Enterobacterales carrier of is Z22.359 (Carrier of Enterobacterales, unspecified). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z22.359.
Within Z22.35, choose Z22.359 (unspecified) only when documentation doesn't support a more specific option: carbapenem-resistant Enterobacterales (Z22.350) and other Enterobacterales (Z22.358).
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.
