找到明文規定了：

https://www.medicare.gov/Pubs/pdf/11036-Enrolling-Medicare-Part-A-Part-B.pdf

 

"What's a Part A late enrollment penalty?

If you get Part A for free, you won't have to pay a Part A late enrollment penalty if you decide to enroll after you first become eligible. "

除非沒有資格享受免費Part A，也就是SS沒交夠年份的人。
