401K rollover on 1099R affecting Medicare premium

[watkcapt45]

Will the large amount on my 1099-R, which was a 401K rollover to a traditional IRA and not income, affect my Medicare premium?

Because a rollover from a 401(k) to a traditional IRA is nontaxable income, it does not add to your AGI and has no effect on your Medicare IRMAA.
