Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Rheumatic disease of pulmonary valve
Other codes that can never be billed with I09.89
These codes carry an Excludes1 note pointing at I09.89. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I09.89 alone.
- I37Nonrheumatic pulmonary valve disorders
Risk adjustment
I09.89 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
I09.89 is named in 18 Medicare coverage policies — 18 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
