As a Medical billing team member or Physician office you might have worried for a incorrect denial received from Medicare for CPT 90661 or 90688, but here is a happy news for you all. CPT 90661 or 90688 was denied incorrectly as FDA (Federal Food and Drug Administration) approval or Performed by a Centralized biller. Both 90661 and 90688 received approval from FDA approval with effective date as November 20, 2012 and August 16, 2013 respectively, now due to delay in receipt of this information claims are denied incorrectly. With denial reason 114 FDA not approved and 170 performed by this provider. According to NOVITAS – As of January 13 th 2014 FDA approval and Centralized biller details has been updated in their system, hence no action required from provider since A mass adjustment project is being initiated to automatically adjust claims that may have denied in error.
