What happens if your ssi payment isn't enough to pay for the medicare insurance?

not sure which you are talking about but here's what is happening....
Beginning this spring, look for your new Medicare card in the mail.
Plan holder since M## 2### This spring: Look for your new Medicare card in the mail Beginning April 2018 and through April 2019, the Centers for Medicare & Medicaid Services (CMS) will be sending you a replacement Medicare card. The new cards do not include a Social Security number and will help to prevent *****, reduce identity theft and safeguard taxpayer dollars.

What does this mean for you? • You will receive a new Medicare card with a new Medicare number that is NOT based on your Social Security number. Begin using your new card immediately upon receiving it and destroy your old Medicare card. • Your benefits will not change with the new Medicare card - that is true for your Medicare benefits and your plan benefits under your AARP® Medicare Supplement Plan, insured by UnitedHealthcare Insurance Company. • UnitedHealthcare is prepared to process all claims using the new Medicare number. • Keep your existing AARP Medicare Supplement health insurance ID card. This card will not be affected by the new Medicare number. You will NOT be receiving a new AARP Medicare Supplement health insurance ID card. Learn more about your new Medicare card by visiting the CMS website.

If you have questions about your AARP Medicare Supplement plan insured by UnitedHealthcare Insurance Company, please call UnitedHealthcare at 1-800-523-5800.

If you are a senior citizen, you should know by now, nothing is ever free. Ha Ha. But seriously, you don't say your exact age or where you are located. If you are in the United States and a citizen or permanent resident, you will qualify for Medicare Part A at age 65. If you worked in the US, you had FICA taxes withheld from your pay and this is part of what those FICA taxes were for. If the coverage is not as substantial as you like, you have the option to purchase medicare supplements which will offer additional coverage. If you are low income, you may qualify for medicaid but if you've been able to pay $469/month, it's unlikely your income is low enough to qualify. There is also the Obamacare health plans which you can check on the governments health care exchange which may offer subsidies (paid for by taxpayers) to help reduce what you have to pay for health insurance. Just be careful before purchasing one that you understand what you are getting, many of these plans have very high deductibles and coinsurance making them almost useless.
