Excludes1 — never code together
The conditions below can never be reported together with F03.A on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- mild neurocognitive disorder due to known physiological condition with or without behavioral disturbance (F06.7-)
Excludes2 — not included here — inherited from Chapter 5
The conditions below are not part of F03.A, but a patient may have both at the same time. When documentation supports it, F03.A and the excluded code may both be reported.
- symptoms, signs and abnormal clinical laboratory findings, not elsewhere classified (R00-R99)
Excludes2 — not included here — inherited from F03
The conditions below are not part of F03.A, but a patient may have both at the same time. When documentation supports it, F03.A and the excluded code may both be reported.
