About coding mobility reduced
The ICD-10-CM code for mobility reduced is Z74.09 (Other reduced mobility).
Within Z74.0, choose Z74.09 (Other reduced mobility) only when documentation doesn't support a more specific option: bed confinement status (Z74.01).
The conditions in its Excludes2 note aren't part of Z74.09, but may be coded alongside it if the patient has both: wheelchair dependence (Z99.3).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
