About ICD-10 Coding Pro

ICD-10 Coding Pro is a reference platform for the ICD-10-CM diagnosis code set used by medical coders, billers, and clinicians in the United States. The free reference covers all FY2026 codes with includes/excludes notes, billability status, Alphabetic Index terms, and excerpts from the official coding guidelines — built directly from the official CMS and CDC/NCHS code-set releases.
