About coding Amnesic syndrome
The ICD-10-CM code for Amnesic syndrome is F04 (Amnestic disorder due to known physiological condition). The official index lists 7 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F04.
Don't report F04 together with the conditions in its Excludes1 note: amnesia NOS (R41.3), anterograde amnesia (R41.1), dissociative amnesia (F44.0) and retrograde amnesia (R41.2).
The conditions in its Excludes2 note aren't part of F04, but may be coded alongside it if the patient has both: alcohol-induced or unspecified Korsakov's syndrome (F10.26, F10.96) and Korsakov's syndrome induced by other psychoactive substances (F13.26, F13.96, F19.16, F19.26, F19.96).
Code first: the underlying physiological condition.
