InterQual Decision Support

The Gold Standard in Evidence-Based Clinical Decision Support

Healthcare stakeholders have always wanted to ensure that care delivery is built on a solid, scientifically valid foundation of medical evidence, both to improve quality and to become more efficient. Over 30 years ago, the InterQual product line was founded on the desire to establish that foundation and to empower providers, payors and others to more easily communicate, collaborate and ultimately determine what is best for patients.

Today, McKesson's InterQual products are the undisputed gold standard in evidence-based clinical decision support. Our criteria cover the medical and behavioral health continuums of care, so they can be applied in a range of clinical situations. InterQual products are used by:

  • Over 300 health plans 
  • Over 3,700 hospitals
  • The Centers for Medicare & Medicaid Services
  • Military Health System
  • 21 Veterans Integrated Service Networks (175 facilities)
