You are a Do-It-Yourselfer, a researcher, or both.
Several of our Medicare companies have just the DIY tools you need. But, only several.
And the reason so few companies provide this service to DIY'ers is the high rate of application errors and/or omissions that result in rejections and delays in coverage.
Let's face it, a gap in health insurance coverage can be life -threatening, or quickly break your bank. That said...

If we are licensed and appointed in your area, you will be able to enroll on your own with the tools below, if you wish.
However, we love what we do. If you have any struggles in the enrollment process, or hit a dead end, just let us know.

Yours, with our thanks for answering 2 quick LTC questions.
You will need your Medicare number to enroll in Medicare insurance. To get your Medicare number, you must apply at the Social Security Administration. Technically, (unless you qualify for automatic enrollment,) it is the Social Security Administration that applies on your behalf and at your bequest to the Centers for Medicare and Medicaid, but only for the part(s) of Medicare for which you are eligible.
Actually, you can do it over the phone, or online. Either way, it will take some time for your request to move through the information pipeline. Approximately, a couple of weeks. Waiting for your red, white, and blue Medicare card doesn't keep you from shopping and comparing your options, however.
