About coding dissociative amnesia
The ICD-10-CM code for dissociative amnesia is F44.0 (Dissociative amnesia). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on F44.0.
Within F44 (dissociative and conversion disorders), F44.0 is specifically for dissociative amnesia. Related codes cover dissociative fugue (F44.1), dissociative stupor (F44.2), conversion disorder with motor symptom or deficit (F44.4), conversion disorder with seizures or convulsions (F44.5), conversion disorder with sensory symptom or deficit (F44.6), conversion disorder with mixed symptom presentation (F44.7), other dissociative and conversion disorders (F44.8) and dissociative and conversion disorder, unspecified (F44.9).
Don't report F44.0 together with the conditions in its Excludes1 note: amnesia NOS (R41.3), anterograde amnesia (R41.1), dissociative amnesia with dissociative fugue (F44.1) and retrograde amnesia (R41.2).
The conditions in its Excludes2 note aren't part of F44.0, but may be coded alongside it if the patient has both: alcohol-or other psychoactive substance-induced amnestic disorder (F10, F13, F19 with .26, .96), amnestic disorder due to known physiological condition (F04) and postictal amnesia in epilepsy (G40.-).
