About coding debility
The ICD-10-CM code for debility is R53.81 (Other malaise). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R53.81.
Within R53.8, choose R53.81 (Other malaise) only when documentation doesn't support a more specific option: chronic fatigue, unspecified (R53.82) and other fatigue (R53.83).
Don't report R53.81 together with the conditions in its Excludes1 note: age-related physical debility (R54).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
