ICD-10-CM
Diagnosis codes for outpatient and professional services, with the verified E11.9 example.
Documentation draft — not a verified product specification. Detail panels listed below are described as "if supported" in the source document; do not treat them as confirmed until verified in the application.
Overview
ICD-10-CM is used for diagnosis coding in U.S. healthcare settings. It is the diagnosis classification used for outpatient and professional services.
Who should use it
Medical coders, coding students, coding auditors and billing staff researching a diagnosis code.
Prerequisites
An Assurlytics account with access to Code Lookup. Use non-PHI information only.
Inputs
Selected code system (ICD-10-CM) and a known code or relevant clinical term.
Step-by-step instructions
- Open Code Lookup.
- Select ICD-10-CM.
- Enter
E11.9or a diagnosis phrase. - Submit the search or select a suggestion, depending on the actual interface.
- Inspect the displayed code and description.
- Review any available notes, related codes or AI explanation.
- Validate the correct code-year guidelines and documentation before use.
Example (synthetic / non-PHI only)
E11.9 — Type 2 diabetes mellitus without complications. This is the verified example from the approved mockup. It demonstrates code lookup, not diagnosis selection for an actual patient.
Understanding results
What a detailed code page may explain, if supported: full code/title, billable/specific status, inclusion/exclusion notes, code hierarchy, related codes, documentation considerations and source/version. Do not claim any of these panels exist until verified in the application.
Limitations
- Confusing similar diagnoses is a common pitfall; a general term does not by itself support the most specific code.
- Do not use outdated code-year data.
- Treating an AI explanation as official coding instruction is incorrect; AI content is advisory.
Troubleshooting
- No results: confirm the ICD-10-CM tab, spelling and supported code year.
- Unexpected description: confirm the exact code, year and source.
- AI answer differs from the official source: follow the authoritative source.
