Typically, beneficiaries cannot enroll in a Medicare Advantage Plan outside of the Open Enrollment Period. However, in certain situations a Special Election Period (SEP) may be used during the other months of the year so that beneficiaries may be able to join, switch, or drop a Medicare Advantage HMO plan or a Prescription Drug plan.
Please call HealthSun Health Plans Member Services Department if you would like more information about enrollment in our Medicare Advantage plans:

How can I find out if my provider participates in HealthSun Health Plans network?
You can find participating doctors by searching our Provider Directory.
How can I get Extra Help with my Medicare costs?
Extra Help is also known as the Low Income Subsidy (LIS). The LIS program is for Medicare beneficiaries with limited income and resources to help them pay for their prescription drug costs including monthly premiums, annual deductibles, and copayments. Many Medicare beneficiaries are eligible for these savings and don’t know it. Those who qualify will enjoy free drug coverage or reduced costs on their Part D benefits.
