Common issues

Some of the more common fraud, waste or abuse issues have to do with coding. These include unbundling, up-coding and the use of exclusion codes and add-ons without the primary Current Procedural Terminology (CPT®) code.* Another common issue is using a diagnosis or procedure code that doesn’t match the member’s age or gender. Other issues include: 


  • Excessive use of units 

  • Misuse of benefits 

  • Claims for services that weren’t supplied

  • Conflicts of interest and self-referrals  

  • Gifts received in exchange for directing Medicare and Medicaid patients to a business
