About coding boarder
The ICD-10-CM code for boarder is Z76.4 (Other boarder to healthcare facility). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z76.4.
Within Z76, choose Z76.4 (Other boarder to healthcare facility) only when documentation doesn't support a more specific option: 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), healthy person accompanying sick person (Z76.3), Malingerer [conscious simulation] (Z76.5) and persons encountering health services in other specified circumstances (Z76.8).
Don't report Z76.4 together with the conditions in its Excludes1 note: homelessness (Z59.0-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
