In instances where your earnings surpass the threshold specified by the IRS, the surplus IRMAA (income-related monthly adjusted amount) fees are unavoidable, regardless of whether your coverage is through Original Medicare with a Medicare Supplement or a Medicare Advantage scheme.
Should your earnings exceed the established ceiling and your coverage plan for medication is through Medicare Advantage with Prescription Drug coverage (Part C) or standalone Medicare Prescription Drug Plans (Part D), an extra IRMAA surcharge is mandatory, irrespective of whether your premiums are subtracted from your Social Security benefits or you remit payment directly because your Social Security benefits have yet to commence.
Moreover, neglecting to sign up for a Medicare Part D prescription drug plan within the designated period not only leaves you devoid of pharmaceutical coverage, but also subjects you to a penalty for belated enrollment in Part D.
