Abstract: The publication of the Patient Protection and Affordable Care Act (PPACA), section 6405 - "Physicians Who Order Items or Services Required to be Medicare Enrolled Physicians or Eligible Professionals" (regulation CMS 6010-F), contains a requirement for certain physicians and non-physician practitioners to enroll in the Medicare program for the sole purpose of ordering or referring items or services for Medicare beneficiaries. The PPACA has an effective date applicable to written orders and certifications made on or after July 1, 2010. The CMS 855O allows a physician to receive a Medicare identification number (without being approved for billing privileges) for the sole purpose of ordering and referring Medicare beneficiaries to Medicare approved providers and suppliers. This new Medicare application form allows physicians who do not provide services to Medicare beneficiaries to be given a Medicare identification number without having to supply all the data required for the submission of Medicare claims. It also allows the Medicare program to identify ordering and referring physicians without having to validate the amount of data necessary to determine claims payment eligibility (such as banking information), while continuing to identify the physician's credentials as valid for ordering and referring purposes.
