About coding opening status artificial
The ICD-10-CM code for opening status artificial is Z93.9 (Artificial opening status, unspecified). The official index lists 18 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z93.9.
Within Z93, choose Z93.9 (unspecified) only when documentation doesn't support a more specific option: tracheostomy status (Z93.0), gastrostomy status (Z93.1), ileostomy status (Z93.2), colostomy status (Z93.3), other artificial openings of gastrointestinal tract status (Z93.4), cystostomy status (Z93.5), other artificial openings of urinary tract status (Z93.6) and other artificial opening status (Z93.8).
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.
