This is the public slice. Year-over-year history, every code, payment detail, group affiliations, and phone numbers for Jason Ysasaga are one search in Prospect 811.

Where this data comes from. Provider identity, specialty, and practice location come from CMS's public NPPES registry (the National Plan & Provider Enumeration System), the official record of every NPI ever issued. Deactivated NPIs are excluded. Addresses are what the provider filed and can lag a move. Where a profile shows Medicare context, it comes from CMS's public utilization, Part D, and Open Payments files: traditional Medicare fee-for-service only, and CMS suppresses any provider-and-code line under 11 beneficiaries before publishing. An Open Payments record is a disclosed relationship, not evidence a clinician uses a product. Prospect 811 organizes public data; it doesn't add to or alter it. Not affiliated with or endorsed by CMS. Full detail on the data page.
