SSA will correct its records if the beneficiary can supply more accurate information
than SSA received from IRS. The only better information that the beneficiary can provide
to prove that the MAGI information received from IRS during the IRMAA Annual Verification
process is incorrect is:
documentation of an obvious IRS transcription error in tax-exempt interest income
for the tax year that SSA verified with IRS (HI 01120.050F.).
documentation of a change in living arrangement for Married Filing Separately--Lived
Apart All Year (HI 01120.060).
The beneficiary may request a New Initial Determination or appeal any adjustments
made to the IRMAA as a result of the IRMAA Annual Verification determination.
