About coding Wernicke-Korsakoff's syndrome or psychosis
The ICD-10-CM code for Wernicke-Korsakoff's syndrome or psychosis is F10.9 (Alcohol use, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F10.9.
Within F10, choose F10.9 (use, unspecified) only when documentation doesn't support a more specific option: abuse (F10.1) and dependence (F10.2).
To report this condition, pick the subcode that matches the documentation: F10.90 (uncomplicated), F10.91 (in remission), F10.92 (with intoxication), F10.93 (with withdrawal), F10.94 (with alcohol-induced mood disorder), F10.95 (with alcohol-induced psychotic disorder), F10.96 (with alcohol-induced persisting amnestic disorder), F10.97 (with alcohol-induced persisting dementia) and 2 more.
Don't report F10.9 together with the conditions in its Excludes1 note: alcohol abuse (F10.1-) and alcohol dependence (F10.2-).
