J04.2 — Acute laryngotracheitis
J04.2 is a billable, specific ICD-10-CM code for acute laryngotracheitis. 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.
- acute obstructive laryngotracheitis (J05.0)
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- chronic laryngotracheitis (J37.1)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Laryngotracheitis NOS
- Tracheitis (acute) with laryngitis (acute)
Risk adjustment
J04.2 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
J04.2 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.
