About J04.1

J04.1 is the ICD-10-CM diagnosis code for acute tracheitis. It belongs to category J04 (acute laryngitis and tracheitis), block J00-J06 (acute upper respiratory infections) and chapter 10 (diseases of the respiratory system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within J04 (acute laryngitis and tracheitis), J04.1 is specifically for acute tracheitis. Related codes cover acute laryngitis (J04.0), acute laryngotracheitis (J04.2) and Supraglottitis, unspecified (J04.3).

To report this condition, pick the subcode that matches the documentation: J04.10 (without obstruction) and J04.11 (with obstruction).

The conditions in its Excludes2 note aren't part of J04.1, but may be coded alongside it if the patient has both: chronic tracheitis (J42).

Use an additional code (B95-B97) to identify infectious agent.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
