Excludes1 — never code together — inherited from C78
The conditions below can never be reported together with C78.39 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 C78
The conditions below are not part of C78.39, but a patient may have both at the same time. When documentation supports it, C78.39 and the excluded code may both be reported.
- lymph node metastases (C77.0)
