About coding hypertrophic laryngotracheitis
The ICD-10-CM code for hypertrophic laryngotracheitis is J37.1 (Chronic laryngotracheitis).
Within J37 (chronic laryngitis and laryngotracheitis), J37.1 is specifically for chronic laryngotracheitis. Related codes cover laryngitis (J37.0).
Don't report J37.1 together with the conditions in its Excludes1 note: chronic tracheitis (J42).
The conditions in its Excludes2 note aren't part of J37.1, but may be coded alongside it if the patient has both: acute laryngotracheitis (J04.2) and acute tracheitis (J04.1).
Don't confuse with (Excludes1 for J37.1)
- chronic tracheitis (J42)
