From the official ICD-10-CM alphabetic index entry “Laryngitis (acute) (edematous) (fibrinous) (infective) (infiltrative) (malignant) (membranous) (phlegmonous) (pneumococcal) (pseudomembranous) (septic) (subglottic) (suppurative) (ulcerative)”. Page updated September 29, 2026.
About coding laryngitis
The ICD-10-CM code for laryngitis is J04.0 (Acute laryngitis). The official index lists 19 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J04.0.
Within J04 (acute laryngitis and tracheitis), J04.0 is specifically for acute laryngitis. Related codes cover acute tracheitis (J04.1), acute laryngotracheitis (J04.2) and Supraglottitis, unspecified (J04.3).
Don't report J04.0 together with the conditions in its Excludes1 note: acute obstructive laryngitis (J05.0).
The conditions in its Excludes2 note aren't part of J04.0, but may be coded alongside it if the patient has both: chronic laryngitis (J37.0).
