Illinois medical license lookup
The license itself is verified on the Illinois Department of Financial and Professional Regulation search, not by CMS or any directory. 241,958 registry records list a practice address in Illinois, and not all of them hold a state license. Search the provider's name there to see license status, expiration and any public orders.

Common questions
Is the Illinois license search free?
Yes. The Illinois Department of Financial and Professional Regulation publishes its license search at no charge. It shows license status, license number and expiration, and board actions the board has made public.
Does an NPI prove a provider is licensed?
No. An NPI is an identifier CMS issues for billing. It is not a license and does not confirm board certification. Check the state board search for the license itself.
Does the Illinois search show malpractice payments?
It depends on the board, so open one profile on the Illinois Department of Financial and Professional Regulation search and read its fields. Some boards list malpractice judgments or settlements on the licensee profile; many list only license status and public board actions. The full payment history is in the National Practitioner Data Bank, which is not open to the public for individual lookups.
