Excludes1 — never code together — inherited from C85
The conditions below can never be reported together with C85.9 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 — inherited from C81-C96
The conditions below are not part of C85.9, but a patient may have both at the same time. When documentation supports it, C85.9 and the excluded code may both be reported.
