About coding genetic carrier of
The ICD-10-CM code for genetic carrier of is Z14.8 (Genetic carrier of other disease). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z14.8.
Within Z14, choose Z14.8 (of other disease) only when documentation doesn't support a more specific option: hemophilia A carrier (Z14.0) and cystic fibrosis carrier (Z14.1).
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.
