About coding accompanying sick person boarder
The ICD-10-CM code for accompanying sick person boarder is Z76.3 (Healthy person accompanying sick person).
Within Z76 (persons encountering health services in other circumstances), Z76.3 is specifically for healthy person accompanying sick person. Related codes cover encounter for issue of repeat prescription (Z76.0), encounter for health supervision and care of foundling (Z76.1), encounter for health supervision and care of other healthy infant and child (Z76.2), other boarder to healthcare facility (Z76.4), Malingerer [conscious simulation] (Z76.5) and persons encountering health services in other specified circumstances (Z76.8).
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.
