Excludes1 — never code together

The conditions below can never be reported together with C64 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • malignant carcinoid tumor of the kidney (C7A.093)
  • malignant neoplasm of renal calyces (C65.-)
  • malignant neoplasm of renal pelvis (C65.-)
