I received my first Medicare pre,ium bill, and was surprised to find that the amount due is based on a quarterly payment schedule.
Can I instead pay monthly?

Hi,

Probably not. Part B Medicare premiums are billed on a quarterly basis if they can't be withheld from a person's benefits, although if a person is also paying premiums for Part A of Medicare then they're billed monthly. If and when you start drawing Social Security benefits, your Part B premiums will then be deducted on a monthly basis.
