Excludes2 — not included here

The conditions below are not part of F06.3, but a patient may have both at the same time. When documentation supports it, F06.3 and the excluded code may both be reported.

  • mood disorders due to alcohol and other psychoactive substances (F10-F19 with .14, .24, .94)
  • mood disorders, not due to known physiological condition or unspecified (F30-F39)

Excludes1 — never code together — inherited from F06

The conditions below can never be reported together with F06.3 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.-)
