McCormack offers several other useful suggestions to coders reporting EEG testing situations. "You can find a listing of -approved- diagnoses for EEGs on the CMS Web site," she says, located at http://www.cms.hhs.gov/manuals/downloads/ncd103_xref_cim_to_ncd.pdf. "Check with your local Medicare or Medicaid carrier for any local coverage determination requirements," she says.

Many commercial and private insurance companies now have Web sites where we as providers can gain access to a patient's specific policy provisions."
