Other codes that can never be billed with A18.01

These codes carry an Excludes1 note pointing at A18.01. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A18.01 alone.

  • M01Direct infections of joint in infectious and parasitic diseases classified elsewhere
  • M49Spondylopathies in diseases classified elsewhere

Risk adjustment

A18.01 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.

Medicare coverage

A18.01 is named in 26 Medicare coverage policies 26 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
