Official ICD-10-CM descriptor (FY2026)
Acute laryngitis and tracheitis
J04 is a category heading, not a billable code. CMS does not accept it on a claim; report one of the more specific codes beneath it.
Excludes1
Not coded here. An Excludes1 code should never be reported at the same time as the code above it.
- acute obstructive laryngitis [croup] and epiglottitis (J05.-)
Excludes2
Not included here. The condition is not part of this code, but a patient may have both, and both codes may be reported together.
- laryngismus (stridulus) (J38.5)
Use additional code
Report an additional code to identify the associated condition.
- code (B95-B97) to identify infectious agent.
Code also
Two codes may be needed; sequencing depends on the reason for the encounter.
- influenza, if present, such as:
- influenza due to identified novel influenza A virus with other respiratory manifestations (J09.X2)
- influenza due to other identified influenza virus with other respiratory manifestations (J10.1)
- influenza due to unidentified influenza virus with other respiratory manifestations (J11.1)
