ICD-10 Code J05.10 – Acute epiglottitis without obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J05.10 – Acute epiglottitis without obstruction
What it is
Use this code for acute inflammation of the epiglottis when there is no documented airway obstruction. It identifies a serious upper-airway infection or inflammation that needs prompt clinical attention.
Clinical signs
Clinical features vary; refer to documentation. Commonly described findings include sore throat, painful swallowing, fever, muffled voice, drooling, and visible epiglottic inflammation on exam or laryngoscopy.
When to use this code
Assign J05.10 when the record clearly states acute epiglottitis and specifically notes no obstruction. Use it for confirmed diagnoses in outpatient, emergency, or inpatient documentation when the provider does not describe airway compromise.
If the chart mentions stridor, respiratory distress, or obstruction, review the documentation carefully before coding. When the note is unclear, check documentation rather than assume the nonobstructive form.
Do not use for
Do not use this code for epiglottitis with airway obstruction, or when the diagnosis is only suspected and not confirmed. Do not code it for chronic or non-acute throat conditions.
Coding tip
Look for the exact phrase “without obstruction” or equivalent provider wording before assigning J05.10.
