  4.  2009 Medicare Advantage, Cost, and Demonstration Plans
  5.  Data as of November 5, 2008.  Includes all contracts/plans regardless of 2009 approval status.  PACE, Special Needs Plans, Part B Only
      Plans, and Employer sponsored plans (800 series) are excluded. (Last Updated 11/05/08)
  6.  Notes: Data are subject to change as contracts are being finalized.  Gap coverage descriptions for the 2009 benefit year are have been
      revised.  The percentage of “Generic” products and the percentage of “Brand” products covered in the gap are each separately calculated and
      the following descriptions are added:  “All”: 100% of drugs are covered through the gap, “Many”: ≥65% to <100% of drugs are covered through
      the gap, “Some”: ≥10% to <65 % of drugs are covered through the gap, “Few”: >0% to <10% of drugs are covered through the gap (and must also
      be >15 products covered through the gap), “No Gap Coverage”:  0% of drugs are covered through the gap (or ≤15 products covered through the
      gap).  A label of “All Formulary Drugs” is applied for plans that cover 100% of “Generic” and 100% of “Brand” products (either by covering
      all drug products in the gap or by having no initial coverage limit).
  7.  * Indicates plan does not offer Part D drug coverage.
