About coding amnesia

The ICD-10-CM code for amnesia is R41.3 (Other amnesia). The official index lists 8 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R41.3.

Within R41, choose R41.3 (Other amnesia) only when documentation doesn't support a more specific option: Disorientation, unspecified (R41.0), Anterograde amnesia (R41.1), retrograde amnesia (R41.2), 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 R41.3 together with the conditions in its Excludes1 note: amnestic disorder due to known physiologic condition (F04), amnestic syndrome due to psychoactive substance use (F10-F19 with 5th character .6), mild memory disturbance due to known physiological condition (F06.8) and transient global amnesia (G45.4).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
