Other codes that can never be billed with C63

These codes carry an Excludes1 note pointing at C63. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C63 alone.

  • C61Malignant neoplasm of prostate
  • C68Malignant neoplasm of other and unspecified urinary organs
  • C76Malignant neoplasm of other and ill-defined sites
  • C44Other and unspecified malignant neoplasm of skin

Code to one of these instead C63

6 child codes. Green means billable.
