1. Choose the classification and release
Choose the U.S. ICD-10-CM edition that applies to the service or discharge date and care setting. Interface language changes navigation; official code titles and instructions remain in English.
2. Search, then check the index
Search a code or documented English diagnosis in ICD-10-CM. Treat results as navigation. Open the relevant Alphabetic Index entry and follow its subterms and cross-references. The external-cause, drug and neoplasm indexes provide different contexts; do not substitute one table for another.
3. Read the complete code page
Check the title, required specificity, parent categories, code-level instructions and inherited instructions together. A billable or specific label does not by itself establish coverage or payment. Open linked instructions and the official guidelines before assigning a code.
4. Keep history in its proper context
Compare releases to understand when a code or instruction changed. A historical conversion or mapping supports investigation; it is not automatic permission to substitute a previous code. Check the source and date attached to any Medicare context, and keep it separate from the diagnosis classification.
5. Save or share the versioned reference
Save useful code pages to your workspace or share their versioned URLs. Include the classification and release when discussing a code. Guest saves stay on that browser; account saves can synchronize. Share reference links without patient information.
6. Resolve uncertainty at the source
Open the official release files and guidelines from the source library. If a page differs from the source, report the URL, edition, and source so we can investigate.
Reference use and review limits
The website provides educational reference information. It does not diagnose conditions, select a patient-specific code or guarantee payment. Verify the applicable official guidelines, encounter documentation and local requirements. Original launch guides have not been independently reviewed by a credentialed clinical coding specialist. Do not submit patient names, clinical records or other identifiable patient information.
