Independent Diagnostic Testing Facility (IDTF) Enrollment

An IDTF may be a fixed location, a mobile entity, or an individual non-physician practitioner. It is independent of a physician's office or hospital; however, these rules apply when an IDTF furnishes diagnostic procedures in a physician's office. See the CMS Internet Only Manual (IOM), Publication 100-08, Medicare Program Integrity Manual, Chapter 10.2.2.4 - IDTF Enrollment Standards.

A fixed IDTF (non-mobile or hospital based) cannot:

  • Share a practice location with another Medicare-enrolled individual or organization
  • Lease or sublease its operations or practice location to another Medicare enrolled individual or organization
  • Share diagnostic testing equipment used in initial diagnostic test with another Medicare-enrolled individual or organization
  • If contractor determines that an IDTF is leasing to subleasing its operations to another individual or organization, contractor shall revoke the supplier's Medicare billing privileges
  • If a group practice exists to solely provide professional component services for an IDTF's technical components and resides at same practice location at IDTF, group practice, and IDTF are not considered sharing space
    • Group practice shall not provide professional component services for any other organization
