Excludes1 — never code together
The conditions below can never be reported together with C43 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- melanoma in situ (D03.-)
Excludes2 — not included here
The conditions below are not part of C43, but a patient may have both at the same time. When documentation supports it, C43 and the excluded code may both be reported.
