Medicare Advantage Enrollment in Pima County: Nearly 50%
Tuesday, April 27th, 2010When Medicare cuts payments to Medicare Advantage plans, 11.5 million people around the country will see “their Medicare” change. This represents 25% of all Medicare beneficiaries. I recently came across a page on the Medicare website that breaks down Medicare Advantage enrollment in every county in the country. I was shocked to see that in quite a few counties (mostly large urban areas) nearly 50 % of Medicare beneficiaries are enrolled in Medicare Advantage plans.
Throughout Arizona, 34% of Medicare beneficiaries are enrolled in Medicare Advantage. However, in Pima County 44.83 % are enrolled in Medicare Advantage plans. In Maricopa County it’s 43.45%. In Pinal County over 49% of Medicare beneficiaries are enrolled in Medicare Advantage plans.
