Excludes2 inherited from the categories above T86.820
Also inherited, and the opposite of Excludes1: these conditions are not part of T86.820, but a patient can have both, so you may code both.

Risk adjustment
T86.820 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
T86.820 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
