Free medical code lookup
Extract ICD-10 codes from your clinical notes
A ICD-10 code lookup that starts from the note, not the code book: paste clinical text and get reviewable ICD-10 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 codes
The note as written
Diabetes annual review. 58-year-old with type 2 diabetes mellitus and essential hypertension. Reports tingling in both feet. HbA1c is 8.9%. Examination shows reduced sensation to monofilament in both feet consistent with diabetic peripheral neuropathy. Background diabetic retinopathy noted on last screening. Assessment 1. Type 2 diabetes mellitus with diabetic polyneuropathy. 2. Essential hypertension. Plan: optimis…
Suggested ICD-10 codes
G63.2Diabetic polyneuropathy
Evidence: “Diabetes annual review.”
I10Essential (primary) hypertension
Evidence: “58-year-old with type 2 diabetes mellitus and essential hypertension.”
H36.0Diabetic retinopathy
Evidence: “Background diabetic retinopathy noted on last screening.”
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 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 multi-condition follow-up can surface diagnosis candidates while preserving the clinical note as the source of truth.
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 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 extraction works
What ICD-10 codes capture
ICD-10 is the international classification for diseases and related health conditions, used as the foundation for many national diagnosis coding systems.
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.
General models may answer with a country-specific variant when you need the international classification. Notat makes the selected system explicit.
Where ICD-10 fits
ICD-10 supports claims, reporting, quality programs, and patient record organization. This demo focuses on the first step: finding code candidates from clinical documentation.
- International diagnosis classification
- Public health reporting and standardized condition categories
- Understanding how national ICD-10 variants relate to the WHO foundation
How it compares with related coding systems
ICD-10 variants pair with local procedure systems such as CPT, OPCS-4, CCAM, OPS, or ICD-10-PCS depending on market.
ICD-10-CM
Diagnosis coding system used in the United States.
Notat keeps ICD-10-CM separate from ICD-10 so reviewers can work from the right code set.
What is ICD-10-CM
ICD-10-UK
Diagnosis coding system used in the United Kingdom.
Notat keeps ICD-10-UK separate from ICD-10 so reviewers can work from the right code set.

ICD-10-GM
Diagnosis coding system used in Germany.
Notat keeps ICD-10-GM separate from ICD-10 so reviewers can work from the right code set.
What is ICD-10-GM
AI suggests. You decide.
This demo generates ICD-10 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 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?
ICD-10 is the international classification for diseases and related health conditions, used as the foundation for many national diagnosis coding systems. The extractor above shows how documented clinical text can be mapped to reviewable ICD-10 suggestions.
Is this an ICD-10 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 code candidates with the supporting text, in one pass.
