164 healthcare practices and sole proprietors registered for an NPI in Illinois in the week ending October 11, 2026, 107 of them brand-new organizations (practices, clinics, agencies, suppliers) and 57 sole proprietors.
Behavioral health led the week with 79, followed by medical practices & clinics (29) and dme, pharmacy & transport (26). The busiest cities were Chicago (45), Elmhurst (5), Rockford (4). That is 3.4% of the 4,841 new registrations nationwide, ranking Illinois #8 of 52 states and territories this week.
At this week's pace Illinois adds roughly 711 new practices a month. Every one of them has to be credentialed with payers and set up for billing in the months after it registers, which is why credentialing and medical-billing companies use this list as a call sheet: the practice is in the registry one to two weeks after it enrolled, usually before it has signed with anyone.
Each practice is filed by the specialty code it registered under. Categories with a link have their own weekly page.
Tracking started with the week ending October 11, 2026; this chart fills in a bar a week.

About 711 a month at the current pace (164 in the week ending October 11, 2026; 164 a week on average over the weeks tracked). The count includes new organizations and individuals who registered as sole proprietors; employees who registered for an NPI to take a job are excluded.
The National Plan and Provider Enumeration System (NPPES), run by CMS. Every provider and organization that bills insurance needs an NPI, and CMS publishes the weekly registrations as a public file. PanelReady reads that file, keeps the practices and sole proprietors in Illinois, sorts them into six categories and refreshes this page every week.
CMS posts each week's file about a week after the week ends, and most registrations in it are one to six days old at that point, so a practice shows up here one to two weeks after it registered. Subscribers get the full list the morning the file is posted.
Every Illinois row, not a sample, with the complete phone number, street address, ZIP, NPI, taxonomy code, credential and authorized official, as a spreadsheet every Monday. PanelReady does not sell email addresses; the registry doesn't contain them.
