In simple words: This code describes a mental health problem caused by a known physical issue when no other specific code fits. The physical issue must be documented by the doctor.

Other specified mental disorders due to known physiological condition encompasses mental disorders caused by a documented physical or physiological condition that are not captured by other codes within the F06 category.Examples include, but are not limited to:* Epileptic psychosis NOS* Obsessive-compulsive and related disorder due to a known physiological condition* Organic dissociative disorder* Organic emotionally labile [asthenic] disorder

Example 1: A patient with a history of epilepsy develops psychosis during a seizure. The psychosis is not otherwise explained by another mental disorder. F06.8 would be appropriate in this scenario, with the epilepsy diagnosis coded first., A patient with multiple sclerosis experiences obsessive-compulsive disorder symptoms that are directly related to their MS. F06.8 would be appropriate in this case, with the multiple sclerosis diagnosis coded first., A patient post-stroke exhibits symptoms of dissociative disorder that are attributed to the stroke event.F06.8 would be appropriate, with the stroke diagnosis coded first.

Documentation should clearly link the mental disorder symptoms to the underlying physiological condition. The type of mental disorder should be specified, and the underlying physiological condition should be documented and coded first.Detailed descriptions of the patient's symptoms, onset, and duration should also be included.
