B39.0 — Acute pulmonary histoplasmosis capsulati
B39.0 is a billable, specific ICD-10-CM code for acute pulmonary histoplasmosis capsulati. It is valid for submission on a claim.
Other codes that can never be billed with B39.0
These codes carry an Excludes1 note pointing at B39.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading B39.0 alone.
Risk adjustment
B39.0 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
B39.0 is named in 8 Medicare coverage policies — 8 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
