Other codes that can never be billed with D40

These codes carry an Excludes1 note pointing at D40. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D40 alone.

  • D44Neoplasm of uncertain behavior of endocrine glands
  • D48.5Neoplasm of uncertain behavior of skin

D40 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead D40

4 child codes. Green means billable.
