ICD-10 codes for UTI
UTI coding starts with the site and certainty. N39.0 is common when the site is not specified, but cystitis, pyelonephritis, dysuria without confirmed infection, and organism documentation can change the coding.
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.
2
Press Get codes. The coding system is fixed on this page.
3
Review each suggested code and its evidence, then copy the codes you agree with.

Urinary tract infection ICD-10 codes
Start with the primary code, then move to a more specific related code when the documentation supports it.
| Code | Description | System |
|---|---|---|
N39.0 | Urinary tract infection, site not specified | ICD-10-CM |
N30.00 | Acute cystitis without hematuria | ICD-10-CM |
N30.01 | Acute cystitis with hematuria | ICD-10-CM |
R30.0 | Dysuria | ICD-10-CM |
N10 | Acute pyelonephritis | ICD-10-CM |
B96.20 | Unspecified Escherichia coli as cause of diseases classified elsewhere | ICD-10-CM |
How to choose the right code
Use N39.0 for UTI when the site is not documented. Use N30.00 or N30.01 for acute cystitis when hematuria status is known. Use R30.0 for dysuria when infection is not established. Add organism codes such as B96.20 when culture documents E. coli and local coding rules require it.
Documentation example
“Two days of dysuria, frequency, and suprapubic discomfort. No flank pain or fever. Urine dip positive nitrites and leukocytes, no visible hematuria. Assessment: acute uncomplicated cystitis; nitrofurantoin prescribed.”
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
Is every UTI N39.0?
No. N39.0 is for UTI when the site is not specified. Documented acute cystitis should usually use N30.00 or N30.01 depending on hematuria.
When do I use R30.0?
Use R30.0 for dysuria when the encounter documents painful urination but does not establish a urinary tract infection.
Can AI catch UTI site and organism details?
Notat extracts symptoms, dipstick or culture results, hematuria, flank pain, fever, and assessment as clinical facts, then shows the evidence behind each suggested code.
