Other codes that can never be billed with Q25.79
These codes carry an Excludes1 note pointing at Q25.79. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q25.79 alone.
- I28.1Aneurysm of pulmonary artery
Risk adjustment
Q25.79 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
Q25.79 is named in 25 Medicare coverage policies — 25 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
