F06 — Other mental disorders due to known physiological condition
Is F06 billable?

Excludes1 — never code together
The conditions below can never be reported together with F06 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- unspecified dementia (F03.-)
Code first
The underlying condition below must be sequenced before F06. F06 describes a manifestation and cannot be the principal or first-listed diagnosis.
- the underlying physiological condition
Excludes2 — not included here
The conditions below are not part of F06, but a patient may have both at the same time. When documentation supports it, F06 and the excluded code may both be reported.
