I11.9 — Hypertensive heart disease without heart failure
I11.9 is a billable, specific ICD-10-CM code for hypertensive heart disease without heart failure. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Hypertensive heart disease NOS
Other codes that can never be billed with I11.9
These codes carry an Excludes1 note pointing at I11.9. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I11.9 alone.
Risk adjustment
I11.9 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
I11.9 is named in 27 Medicare coverage policies — 27 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How I11.9 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 I11.9.
