ICD-10 codes for sinusitis
Sinusitis coding depends on acute versus chronic and sinus location. Unspecified acute sinusitis is common, but maxillary, frontal, ethmoidal, and sphenoidal sites have their own codes.
Notat writes the note — and suggests these codes
The same FactsContext™ engine that extracts codes here turns the full consultation into a structured clinical note, with each code tied to the sentence that supports it. You review and sign every note.
Try AI-assisted extraction with visible medical context
Paste a note or record audio. Notat’s FactsContext™ engine extracts the raw clinical facts first, then suggests codes from that context so you can inspect the evidence before using anything.

How to use this tool
1
Paste or dictate a de-identified clinical note — a few sentences is enough.

Sinusitis ICD-10 codes
Start with the primary code, then move to a more specific related code when the documentation supports it.
| Code | Description | System |
|---|---|---|
J01.90 | Acute sinusitis, unspecified | ICD-10-CM |
J01.00 | Acute maxillary sinusitis, unspecified | ICD-10-CM |
J01.10 | Acute frontal sinusitis, unspecified | ICD-10-CM |
J32.9 | Chronic sinusitis, unspecified | ICD-10-CM |
J30.9 | Allergic rhinitis, unspecified | ICD-10-CM |
How to choose the right code
Use J01.- for acute sinusitis and J32.- for chronic sinusitis. Pick a site-specific code when maxillary, frontal, ethmoidal, or sphenoidal involvement is documented. Do not code allergic rhinitis as sinusitis unless sinusitis is diagnosed.
Documentation example
“Ten days of worsening facial pressure, purulent nasal discharge, and maxillary tenderness after viral URI. No orbital symptoms. Assessment: acute maxillary sinusitis; delayed antibiotic prescription and nasal steroid.”
Suggested:
Not direct transcript guessing
FactsContext extracts clinical facts first: diagnoses, symptoms, negatives, findings, test results, medications, and plan decisions.
Raw facts stay usable
The clinician can read and reuse the extracted medical context directly, independent of the generated note.
Built for review
AI suggestions are not a substitute for clinician judgment, payer rules, local coding policy, or the official code set.
FAQ
When is sinusitis chronic?
Chronic sinusitis should be documented clinically as chronic, often with prolonged or recurrent symptoms. Coding then moves from J01.- to J32.-.
How specific should acute sinusitis coding be?
Use the site-specific acute code when the note documents maxillary, frontal, ethmoidal, or sphenoidal sinus involvement.
Can AI distinguish rhinitis from sinusitis?
Notat extracts duration, discharge, facial tenderness, diagnosis, and treatment plan as clinical facts, then suggests the code supported by the assessment.
