I07.9 — Rheumatic tricuspid valve disease, unspecified
I07.9 is a billable, specific ICD-10-CM code for rheumatic tricuspid valve disease, unspecified. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Rheumatic tricuspid valve disorder NOS
Excludes1 inherited from the categories above I07.9
These are not written on I07.9, but they bind it: a note on a category applies to every code beneath it. Billing I07.9 with anything listed here is a denial.
Other codes that can never be billed with I07.9
These codes carry an Excludes1 note pointing at I07.9. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I07.9 alone.
- I36Nonrheumatic tricuspid valve disorders
Risk adjustment
I07.9 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
I07.9 is named in 8 Medicare coverage policies — 8 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
