Free medical code lookup
Extract ICD-10-CM codes from your clinical notes
A ICD-10-CM code lookup that starts from the note, not the code book: paste clinical text and get reviewable ICD-10-CM suggestions with evidence. Notat automates medical notes and coding in one beautiful app for doctors.

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.
Clinical note
Extracted codes
Evidence stays attached for review.
Paste a clinical note or load an example, then press Get codes. Suggestions appear here with the supporting evidence.
AI suggestions must be reviewed by a clinician before use. Do not paste patient-identifying information into this free tool.
From clinical note to ICD-10-CM codes
The note as written
Chief Complaint Elevated and fluctuating blood pressure readings. Medical History The patient has essential hypertension, hyperlipidemia, and osteoarthritis. Medications Lisinopril 20 mg twice daily, atorvastatin, and acetaminophen as needed for joint pain. Review of Systems Cardiovascular: Reports intermittent chest heaviness. Denies palpitations or syncope. Neurologic: Reports headaches and occasional lightheade…
Suggested ICD-10-CM codes
I10Essential (primary) hypertension
Evidence: “Chief Complaint Elevated and fluctuating blood pressure readings.”
E78.5Hyperlipidemia, unspecified
Evidence: “2. Hyperlipidemia. Clinically stable on atorvastatin.”
M19.90Unspecified osteoarthritis, unspecified site
Evidence: “3. Osteoarthritis. Symptoms stable. Continue conservative management with acetaminophen as needed.”
Every suggestion stays linked to the sentence that supports it — review before use.
Start with the note
Paste the clinical text as written. Notat reads across assessment, plan, procedure detail, and discharge context.
Review supported codes
Suggestions stay tied to documented diagnoses, symptoms, procedures, and clinical context - not loose keyword matches.
You make the final call
AI suggests. Clinicians and coders verify against the note, official guidance, and local coding policy before use.

From note to reviewed code
1
Paste the messy note
Use the documentation you already have: progress notes, discharge summaries, consults, H&Ps, or procedure notes.
2
Review ICD-10-CM candidates
Notat identifies documented diagnoses, symptoms, and clinical context, then returns candidates with evidence attached.
3
Verify before use
Check the supporting text and official guidance before copying codes into billing, reporting, or coding queues.
A hypertension follow-up can produce reviewable ICD-10-CM suggestions for elevated blood pressure, hyperlipidemia, and osteoarthritis from one finished note.
What you can verify before copying a code
Suggestions are not final billing determinations. They surface candidate codes and the chart text that supports them, so clinicians and coders can make the final call.
Code suggestions
ICD-10-CM candidates mapped to documented clinical facts.
Supporting evidence
The exact phrase or sentence from the note that supports each code.
Review notes
Signals when documentation may be ambiguous, incomplete, or needs human judgment.

How ICD-10-CM extraction works
What ICD-10-CM codes capture
ICD-10-CM is the United States diagnosis code set used to classify conditions documented in outpatient, office, emergency, and many reporting workflows.
Faster than a code-by-code lookup
A classic code lookup or finder makes you search one term at a time. This extractor reads the whole note, surfaces every documented condition and its likely code candidates in one pass, and keeps the final decision with the clinician, coder, or biller.
A general chatbot may mix code sets or require careful prompting. Notat starts from the selected coding system and the documented encounter.
Where ICD-10-CM fits
ICD-10-CM supports claims, reporting, quality programs, and patient record organization. This demo focuses on the first step: finding code candidates from clinical documentation.
- Documenting patient diagnoses and medical necessity
- Supporting outpatient claims and quality reporting
- Connecting symptoms, chronic conditions, and encounter findings to reviewable codes
How it compares with related coding systems
ICD-10-CM is often reviewed with CPT for outpatient services and ICD-10-PCS for inpatient procedure context.
CPT
Procedure coding system used in the United States.
Notat keeps CPT separate from ICD-10-CM so reviewers can work from the right code set.
What is CPT
ICD-10-PCS
Procedure coding system used in United States inpatient hospital care.
Notat keeps ICD-10-PCS separate from ICD-10-CM so reviewers can work from the right code set.
What is ICD-10-PCS
ICD-10
Diagnosis coding system used in international health reporting.
Notat keeps ICD-10 separate from ICD-10-CM so reviewers can work from the right code set.
What is ICD-10
AI suggests. You decide.
This demo generates ICD-10-CM code suggestions from clinical text for review. It does not submit claims, replace certified coding review, override payer-specific rules, or replace official coding guidelines.
Medical coding questions
Is patient data safe in this workflow?
The free extractor is designed for review workflows, but you should follow your organization’s privacy policy before pasting patient-identifiable data into any web tool.
What if a ICD-10-CM suggestion is wrong?
Treat every result as a candidate. Review the supporting chart text, check official guidance and local rules, and ignore or correct any suggestion that does not match the documented encounter.
Is this a replacement for certified coding review?
No. Code suggestions are not final coding decisions. Always verify against current official guidelines, payer rules, and the documented encounter.
What is ICD-10-CM?
ICD-10-CM is the United States diagnosis code set used to classify conditions documented in outpatient, office, emergency, and many reporting workflows. The extractor above shows how documented clinical text can be mapped to reviewable ICD-10-CM suggestions.
Is this an ICD-10-CM code lookup?
Yes, with one difference: instead of searching code by code, you paste the clinical note and the lookup runs in reverse — Notat finds the documented conditions and returns the matching ICD-10-CM code candidates with the supporting text, in one pass.
