R03.0 — Elevated blood-pressure reading, without diagnosis of hypertension
R03.0 is a billable, specific ICD-10-CM code for elevated blood-pressure reading, without diagnosis of hypertension. It is valid for submission on a claim.
Notes
Additional guidance from the ICD-10-CM tabular list.
- This category is to be used to record an episode of elevated blood pressure in a patient in whom no formal diagnosis of hypertension has been made, or as an isolated incidental finding.
Risk adjustment
R03.0 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
R03.0 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.
