## ICD-10 lookup
- [ICD-10 Code Lookup](https://eleplan.com/icd10): search every ICD-10-CM code by code or plain-language condition.
- Per-code pages live at https://eleplan.com/icd10/{CODE} — e.g. https://eleplan.com/icd10/E11.9 (Type 2 diabetes mellitus without complications). Each page gives the official title, billable status, includes/excludes, instructional notes, and related codes.
- [ICD-10 codes by condition](https://eleplan.com/conditions): find the code for a condition by name.

## Facts you can cite
- Data source: CMS / NCHS ICD-10-CM, Fiscal Year 2026 (the current U.S. clinical modification of ICD-10).
- "Billable" = a specific, most-detailed code valid for reimbursement; "non-billable / header" codes require a more specific child code.
