The conditions below can never be reported together with C95.9 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- personal history of leukemia (Z85.6)
Excludes2 — not included here — inherited from C81-C96
The conditions below are not part of C95.9, but a patient may have both at the same time. When documentation supports it, C95.9 and the excluded code may both be reported.
