§408.63. Billing procedures when monthly benefits are less than monthly premiums. — Inbound Citations

(f) If you fail to file an income tax return for any year after 2004 and IRS informs us that you had modified adjusted gross income above the threshold applicable 2 years after the tax year when you failed to file an income tax return, we will impose the highest income-related adjustment percentage applicable to your income filing status for the effective year. If we later determine that the amount of the income-related monthly adjustment amount imposed was inconsistent with your modified adjusted gross income, we will correct it. The rules in 42 CFR 408.40 through 408.92 will apply to the collection of any retroactive premiums due.
