Excludes1 inherited from the categories above I70.339
These are not written on I70.339, but they bind it: a note on a category applies to every code beneath it. Billing I70.339 with anything listed here is a denial.
Excludes2 inherited from the categories above I70.339
Also inherited, and the opposite of Excludes1: these conditions are not part of I70.339, but a patient can have both, so you may code both.

Other codes that can never be billed with I70.339
These codes carry an Excludes1 note pointing at I70.339. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I70.339 alone.
- I77.6Arteritis, unspecified
Risk adjustment
I70.339 risk-adjusts. Under the CMS-HCC V28 model it maps to these categories:
- HCC 263 Atherosclerosis of Arteries of the Extremities with Ulceration or Gangrene1.118 RAF
- 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.
Medicare coverage
I70.339 is named in 5 Medicare coverage policies — 3 listing it as supporting medical necessity, and 2 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
