Medical necessity is a critical concept in healthcare that determines whether services will be covered by insurance. Understanding and properly documenting medical necessity is essential for successful claims processing and appeals.

  • Services are cost-effective for the condition being treated

Key Considerations

  • Clinical evidence supporting and justifying the service
  • Standard of care requirements
  • Patient-specific factors
  • Alternative treatment options
  • Cost-effectiveness analysis

Documentation Requirements
