Active engagement is not a feeling. It's a status your practice must prove. For 2026 MIPS Promoting Interoperability, CMS requires documented evidence for Immunization Registry Reporting and Electronic Case Reporting. A working interface isn't enough. Your practice needs registration confirmations, active engagement levels (Pre-Production/Validation or Validated Data Production), registry communications, and interface status documentation. Optional TEFCA reporting offers bonus points but requires real proof of participation. Don't rely on vendor claims or memory. Build a proof file now while the reporting period is active. Missing documentation creates compliance risk. Check your evidence today.

Your 2026 Promoting Interoperability score is already being built, which means your evidence file should be taking shape too. A PI Proof File is not a submission-season accessory; it is your practice’s scorekeeper. It moves your team from "we think we are ready" to "we can prove we are ready" by centralizing CEHRT documentation, Security Risk Analysis evidence, public health reporting status, and attestations. Don't rely on good intentions or scattered inboxes. Build a defensible record that connects the dots between your technology, your workflows, and your MIPS submission to ensure you can produce proof when it matters most.
