About coding laryngotracheitis
The ICD-10-CM code for laryngotracheitis is J04.2 (Acute laryngotracheitis). The official index lists 17 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J04.2.
Within J04 (acute laryngitis and tracheitis), J04.2 is specifically for acute laryngotracheitis. Related codes cover acute laryngitis (J04.0), acute tracheitis (J04.1) and Supraglottitis, unspecified (J04.3).
Don't report J04.2 together with the conditions in its Excludes1 note: acute obstructive laryngotracheitis (J05.0).
The conditions in its Excludes2 note aren't part of J04.2, but may be coded alongside it if the patient has both: chronic laryngotracheitis (J37.1).
