Critical: Do Not Panic - Be Responsive

Receiving a MAC audit request is stressful, but it is NOT an accusation of wrongdoing. The most important thing you can do is respond promptly and professionally with complete, organized, and legible medical records.

  • Do NOT miss the deadline - Typically 30-45 days from the date of the MAC letter
  • Do NOT submit incomplete records - Missing documentation = automatic denial
  • Do NOT submit illegible records - If the reviewer can't read it, it doesn't exist

Best Practices for Audit Success
  • Tell a story - The cover sheet should explain WHY the patient needed IRF-level care, not just list facts
  • Highlight strengths - Point the reviewer to the strongest documentation supporting medical necessity
  • Be professional - Maintain a respectful, cooperative tone throughout all communications
  • Anticipate questions - If there are any potential weaknesses in the case, address them proactively
  • Keep copies - Maintain a complete copy of everything you submit for future reference
