ICD-10 Code J31.2 – Chronic pharyngitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J31.2 – Chronic pharyngitis
What it is
J31.2 identifies chronic inflammation of the pharynx. Use it for persistent throat irritation or soreness that is documented as chronic rather than an acute infection.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include ongoing throat discomfort, dryness, clearing of the throat, or a persistent scratchy sensation.
When to use this code
Use J31.2 when the provider documents chronic pharyngitis, chronic throat inflammation, or a long-standing pharyngeal irritation. It may also fit follow-up visits where the condition remains active and is still being evaluated. If the note only describes a sore throat without chronicity, check documentation.
Do not use for
Do not use this code for acute pharyngitis, streptococcal sore throat, or tonsillitis unless chronic pharyngitis is specifically documented. Check documentation when the diagnosis is nonspecific.
Coding tip
Assign J31.2 only when the record clearly supports a chronic pharyngeal condition, not a brief or unspecified throat complaint.
