R75 — Inconclusive laboratory evidence of human immunodeficiency virus [HIV]
R75 is a billable, specific ICD-10-CM code for inconclusive laboratory evidence of human immunodeficiency virus [hiv]. 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.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Nonconclusive HIV-test finding in infants
Other codes that can never be billed with R75
These codes carry an Excludes1 note pointing at R75. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R75 alone.
Risk adjustment
R75 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.
How R75 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 R75.
- HIV›laboratory evidence(nonconclusive)
- HIV›nonconclusive test(in infants)
- Positive›test, human immunodeficiency virus(HIV)
- Human›immunodeficiency virus›laboratory evidence
- Test, tests, testing›HIV›nonconclusive(in infants)
