ICD-10 Code J39.1 – Other abscess of pharynx (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J39.1 – Other abscess of pharynx
What it is
J39.1 identifies a localized abscess in the pharynx, meaning a pocket of pus in the throat area behind the mouth and nose. Use it when the documentation specifically describes a pharyngeal abscess that is not otherwise classified.
Clinical signs
Typical findings may include sore throat, painful swallowing, fever, and swelling or tenderness in the pharyngeal region. Clinical features vary; refer to documentation for the exact site and whether the abscess is confirmed.
When to use this code
Use J39.1 when the provider documents an abscess of the pharynx, including “other abscess of pharynx” or a similar confirmed diagnosis. It fits cases where the infection is located in the pharyngeal tissues and no more specific code is documented. Check documentation if the record instead describes a peritonsillar, retropharyngeal, or other adjacent deep neck infection.
Do not use for
Do not use this code for tonsillar, peritonsillar, or retropharyngeal abscesses unless the documentation clearly supports pharyngeal involvement. Also avoid it when the record only mentions throat pain, swelling, or suspected infection without a confirmed abscess.
Coding tip
Code the most specific abscess site documented, and query the provider if the note uses a general “throat abscess” description.
