7 THINGS TO CONSIDER WHEN CHOOSING OR CHANGING YOUR COVERAGE

1. Coverage: How well does the plan cover the services you need?

2. Your other coverage: If you have other types of health or prescription drug coverage, make sure you understand how that coverage works with Medicare. If you have employment-related coverage or get your health care from an Indian Health or Tribal Health Program, talk to your benefits administrator or insurer before making any changes.

3. Costs: How much are your premiums, deductibles, and other costs? How much do you pay for services like hospital stays or doctor visits? Is there a yearly limit on what you could pay out-of-pocket for medical services? Make sure you understand any coverage rules that may affect your costs.

4. Doctor and hospital choice: Do your doctors accept the coverage? Are the doctors you want to see accepting new patients? Do you have to choose your hospital and healthcare providers from a network? Do you need to get referrals?

5. Prescription drugs: Do you need to join a Medicare Prescription Drug Plan? Do you already have creditable prescription drug coverage? Will you pay a penalty if you join a drug plan later? What's the plan’s overall star rating? What will your prescription drugs cost under each plan? Are your drugs covered under the plan’s formulary? Are there any coverage rules that apply to your prescriptions? Are you eligible for a free  Medication Therapy Management (MTM)  program?

6. Quality of care: Are you satisfied with your medical care? The quality of care and services offered by plans and other healthcare providers can vary. How have Medicare and other people with Medicare rated your health and drug plan’s care and services? 

7. Travel: Will the plan cover you if you travel to another state or outside the U.S.?
