The HHS Office of Inspector General (OIG) has issued a report entitled "Miscoded Claims for Power Wheelchairs in the Medicare Program." According to the OIG, 7% of Medicare standard rehabilitation power wheelchair claims and 23% of complex rehabilitation power wheelchair claims from the first half of 2007 were miscoded because the supplier used procedure codes that did not match the wheelchairs' model information. The OIG believes suppliers may need additional education on power wheelchair coding, and CMS can improve its review of power wheelchair claims.
