About coding Disorientation
The ICD-10-CM code for Disorientation is R41.0 (Disorientation, unspecified).
Within R41, choose R41.0 (Disorientation, unspecified) only when documentation doesn't support a more specific option: Anterograde amnesia (R41.1), retrograde amnesia (R41.2), other amnesia (R41.3), neurologic neglect syndrome (R41.4), other symptoms and signs involving cognitive functions and awareness (R41.8) and unspecified symptoms and signs involving cognitive functions and awareness (R41.9).
Don't report R41.0 together with the conditions in its Excludes1 note: delirium due to known physiological condition (F05).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for R41.0)
- delirium due to known physiological condition (F05)
