I08.8 — Other rheumatic multiple valve diseases
I08.8 is a billable, specific ICD-10-CM code for other rheumatic multiple valve diseases. It is valid for submission on a claim.
Excludes1 inherited from the categories above I08.8
These are not written on I08.8, but they bind it: a note on a category applies to every code beneath it. Billing I08.8 with anything listed here is a denial.
Excludes2 inherited from the categories above I08.8
Also inherited, and the opposite of Excludes1: these conditions are not part of I08.8, but a patient can have both, so you may code both.
Other codes that can never be billed with I08.8
These codes carry an Excludes1 note pointing at I08.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I08.8 alone.
Risk adjustment
I08.8 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
I08.8 is named in 24 Medicare coverage policies — 24 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How I08.8 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to I08.8.
