Excludes1 — never code together — inherited from F53

The conditions below can never be reported together with F53.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • mood disorders with psychotic features (F30.2, F31.2, F31.5, F31.64, F32.3, F33.3)
  • postpartum dysphoria (O90.6)
  • psychosis in schizophrenia, schizotypal, delusional, and other psychotic disorders (F20-F29)

Excludes2 — not included here — inherited from Chapter 5

The conditions below are not part of F53.1, but a patient may have both at the same time. When documentation supports it, F53.1 and the excluded code may both be reported.

  • symptoms, signs and abnormal clinical laboratory findings, not elsewhere classified (R00-R99)

How long has F53.1 existed?
