Excludes1 — never code together — inherited from C43

The conditions below can never be reported together with C43.7 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 C43

The conditions below are not part of C43.7, but a patient may have both at the same time. When documentation supports it, C43.7 and the excluded code may both be reported.

  • malignant melanoma of skin of genital organs (C51-C52, C60.-, C63.-)
  • Merkel cell carcinoma (C4A.-)
  • sites other than skin-code to malignant neoplasm of the site
