Other codes that can never be billed with I70.65
These codes carry an Excludes1 note pointing at I70.65. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I70.65 alone.

I70.65 risk-adjusts. Under the CMS-HCC V28 model it maps to these categories:

- HCC 383 Chronic Ulcer of Skin, Except Pressure, Not Specified as Through to Bone or Muscle0.646 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
