ICD-10 Code J32.4 – Chronic pansinusitis (2026): Diagnosis, Symptoms & Billing Guide

The ICD-10 code for Chronic pansinusitis is J32.4.
2026 ICD-10-CM Diagnosis Code J32.4 – Chronic pansinusitis

What it is

Chronic pansinusitis means long-lasting inflammation affecting all of the paranasal sinuses. Use this code when documentation identifies persistent, diffuse sinus disease rather than a single sinus.

Clinical signs

Common findings include nasal obstruction, facial pressure, mucopurulent drainage, and reduced smell. Clinical features vary; refer to documentation, especially when imaging or endoscopy confirms multi-sinus involvement.

When to use this code

Use J32.4 when the provider documents chronic pansinusitis, chronic sinusitis involving all sinuses, or equivalent wording. It fits ongoing disease lasting weeks to months, not a brief acute episode. If the record names only one sinus, code that specific condition instead.

Do not use for

Do not use this code for acute sinusitis, recurrent acute sinusitis, or chronic sinusitis limited to one or more specific sinuses. Check documentation if the site or chronicity is unclear.

Coding tip

Match the code to explicit documentation of “pansinusitis” or “all sinuses” and avoid assuming it from general sinus symptoms alone.
