J05.0 — Acute obstructive laryngitis [croup]
J05.0 is a billable, specific ICD-10-CM code for acute obstructive laryngitis [croup]. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Obstructive laryngitis (acute) NOS
- Obstructive laryngotracheitis NOS
Other codes that can never be billed with J05.0
These codes carry an Excludes1 note pointing at J05.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading J05.0 alone.
Risk adjustment
J05.0 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
J05.0 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.
