R04.2 — Hemoptysis
R04.2 is a billable, specific ICD-10-CM code for hemoptysis. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Blood-stained sputum
- Cough with hemorrhage
Other codes that can never be billed with R04.2
These codes carry an Excludes1 note pointing at R04.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R04.2 alone.
Risk adjustment
R04.2 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
R04.2 is named in 14 Medicare coverage policies — 14 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
