R04.81 — Acute idiopathic pulmonary hemorrhage in infants
R04.81 is a billable, specific ICD-10-CM code for acute idiopathic pulmonary hemorrhage in infants. 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.
- AIPHI
- Acute idiopathic hemorrhage in infants over 28 days old
Other codes that can never be billed with R04.81
These codes carry an Excludes1 note pointing at R04.81. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R04.81 alone.
Risk adjustment
R04.81 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
R04.81 is named in 5 Medicare coverage policies — 5 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How R04.81 is indexed
