Excludes1 — never code together
The conditions below can never be reported together with O76 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here
The conditions below are not part of O76, but a patient may have both at the same time. When documentation supports it, O76 and the excluded code may both be reported.
