  • Billing Under Another Provider’s ID: Using someone else’s ID number or National Provider Identifier 
  • Incorrect Coding: Using the wrong billing codes or combining codes improperly
  • Unbundling: Separating services that should be billed together
  • Unauthorized Providers: Billing for care provided by non-licensed providers
  • Double Billing: Charging twice for the same service
  • Misrepresenting Level of Care: Claiming a higher level of care than provided
  • Patient Overload: Billing for an excessive number of patients in one day
  • Misusing Modifiers: Applying billing modifiers incorrectly
  • Lack of Documentation: Failing to document medical necessity
  • Over/Underutilization: Providing too much or too little care
  • Billing for No-Shows: Charging for canceled or missed appointments
  • Falsifying Records: Altering clinical notes or documents
