ICD-10 Code J01.81 – Other acute recurrent sinusitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J01.81 – Other acute recurrent sinusitis
What it is
This code identifies repeated episodes of acute sinus inflammation that do not fit a more specific sinusitis category. Use it when the record clearly states acute recurrent sinusitis and no single sinus site is specified.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include nasal congestion, facial pressure, purulent drainage, and recurrent upper respiratory symptoms that improve between episodes.
When to use this code
Use J01.81 when the provider documents acute recurrent sinusitis and the episode is current, not chronic. It is appropriate when the note supports repeated acute flare-ups and does not name a more specific sinus location or subtype.
If the record says “recurrent sinusitis” without clarifying acute versus chronic, check documentation before coding. Code only what is explicitly supported in the clinical note.
Do not use for
Do not use this code for chronic sinusitis or for a single, nonrecurrent acute sinus infection. Do not assume the code applies when recurrence is not documented.
Coding tip
Confirm that “acute recurrent” is stated in the chart and that no more specific sinusitis code is available.
