Verify and search ICD-10-CM diagnosis codes against the official US code set (FY
Verify and search ICD-10-CM diagnosis codes against the official US code set (FY2026, ~98k entries). Pass code (with or without the dot, e.g. E11.9 or E119) to confirm the code exists and list its more-specific child codes, or q to keyword-search code descriptions (e.g. "type 2 diabetes neuropathy"). Optional billable_only=true restricts results to codes valid for claim submission; limit caps results (1-50, default 10). Returns a verified flag, the exact match if any, and matched codes with billable status plus short and long descriptions. Data: CMS/NCHS ICD-10-CM (public domain), refreshed each US fiscal year. Use to confirm diagnosis codes are real and current before placing them in claims, prior authorizations, or clinical documents.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
