About coding waiting list
The ICD-10-CM code for waiting list is Z75.1 (Person awaiting admission to adequate facility elsewhere). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z75.1.
Within Z75 (problems related to medical facilities and other health care), Z75.1 is specifically for person awaiting admission to adequate facility elsewhere. Related codes cover medical services not available in home (Z75.0), other waiting period for investigation and treatment (Z75.2), unavailability and inaccessibility of health-care facilities (Z75.3), unavailability and inaccessibility of other helping agencies (Z75.4), Holiday relief care (Z75.5), other problems related to medical facilities and other health care (Z75.8) and unspecified problem related to medical facilities and other health care (Z75.9).
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.
