楼主，大部分terminal癌症好像直接qualify for social security 的disability Income， 同时也qualify for medicare, 我记得一个朋友就是这样，四十多岁得癌症，提交申请，批准以后就开始领disability Income， 而且马上有medicare， 你可以到SSA办公室问一下或者官网上有标准，不过，你的癌症痊愈了怎么算我不知道，供你参考。

A person can qualify for Medicare insurance when they are under age 65 years if one of the following applies:

• They are receiving Social Security disability benefits.
• They have ESRD.
• They have ALS.

All of the medical problems that make someone eligible to receive disability benefits are listed in the Social Security Administration’s Blue Book. Each listing in the Blue Book has a set of requirements that must be met to be considered eligible for disability benefits. Not every type of cancer has a listing in the Blue Book, and the ones that do, have very specific requirements, so please read this information carefully.

In general, any cancer that is Stage IV or terminal will automatically qualify a person to receive disability benefits. A very serious cancer diagnosis qualifies for the Compassionate Allowance program, which expedites the claim for disability benefits to start receiving money quickly. To qualify for Compassionate Allowance, the cancer must meet one of these requirements:

• The cancer has spread beyond the region of origin
• The cancer is inoperable
• The cancer is recurrent despite treatment
