If you have Medicare Part D or Medicare Advantage and none of the isosorbide mononitrate savings options are applicable or affordable for me, what can you do?
If you are insured with Medicare and the isosorbide mononitrate drug savings options are not applicable to you and still remain unaffordable, then you can check Medicaid eligibility in your state by following the instructions at HealthCare.gov.
The government site is easy to use and after you have selected your state, it will navigate you to the appropriate contact point to make the application. State Medicaid programs may cover the full cost of your medication.
People who qualify for both Medicare and Medicaid are called ‘dual eligibles’.
If you are denied Medicaid for isosorbide mononitrate, and you are still unable to afford your copay or co-insurance element (for example if you are in the coverage gap or Donut Hole) then you may be eligible for a federal support program like Low Income Subsidy. To be eligible for Low Income Subsidy, you need to be a resident in one of the 50 States or the District of Columbia. You can check eligibility online at SSA Medicare D Extra Help. You can also call Social Security at 1-800-772-1213 (TTY 1-800-325-0778).
I am uninsured or underinsured and none of the isosorbide mononitrate prescription saving options are applicable or affordable for me, what can I do?
If you are uninsured or underinsured (for example, isosorbide mononitrate is not covered by your plan) and the drug savings options are not applicable or still unaffordable, then you can check Medicaid eligibility in your state by following the instructions at HealthCare.gov.
The government site is easy to use and you can select your state and it will navigate you to the appropriate contact point to make the application. State Medicaid programs may cover the full cost of your medication.
If you are denied and all else fails, and if you have been prescribed isosorbide mononitrate for an FDA-approved indication, you can call the pharmaceutical company to see if they have any other assistance programs.
I am commercially or privately insured and none of the isosorbide mononitrate prescription saving options are applicable or affordable for me, what can I do?
If your medication is not covered by your plan, you can appeal your insurance company’s decision. Sometimes, a formal appeal can result in the drug being covered if it is deemed medically necessary.
If you cannot afford your copay contribution, then you can check Medicaid eligibility in your state by following the instructions at HealthCare.gov.
However, being privately insured might complicate your eligibility for Medicaid, as having private insurance may be considered in the financial eligibility assessment.
The government site is easy to use and you can select your state and it will navigate you to the appropriate contact point to make the application. If you qualify, state Medicaid may cover the full cost of your medication.
If I have federal, state or commercial insurance and none of the isosorbide mononitrate prescription saving options are applicable or affordable for me, are there any other support organisations that can help me with my co-insurance or copay contributions?
