R03.1 — Nonspecific low blood-pressure reading

Billable / specific codeICD-10-CM

R03.1 is a billable, specific ICD-10-CM code for nonspecific low blood-pressure reading. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

hypotension (I95.-)
maternal hypotension syndrome (O26.5-)
neurogenic orthostatic hypotension (G90.3)

Other codes that can never be billed with R03.1

These codes carry an Excludes1 note pointing at R03.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R03.1 alone.

I95Hypotension

Risk adjustment

R03.1 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

R03.1 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.

How R03.1 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 R03.1.
