ICD-10 code for exhaustion
From the official ICD-10-CM alphabetic index entry “Exhaustion, exhaustive (physical NEC)”. Page updated September 29, 2026.
About coding exhaustion
The ICD-10-CM code for exhaustion is R53.83 (Other fatigue). The official index lists 17 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R53.83.
Within R53.8, choose R53.83 (Other fatigue) only when documentation doesn't support a more specific option: other malaise (R53.81) and chronic fatigue, unspecified (R53.82).
The conditions in its Excludes2 note aren't part of R53.83, but may be coded alongside it if the patient has both: exhaustion and fatigue due to depressive episode (F32.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
