The Delaware Medicare Supplement Refund Calculation Form is a document used by Delaware residents to calculate the amount of refund they are eligible for from their Medicare Supplement insurance premiums. This form is used to determine the number of months for which a Medicare supplement refund is due and the amount of the refund. There are two types of Delaware Medicare Supplement Refund Calculation Form: one for individuals and one for couples. The form requires detailed information about the individual or couple's Medicare Supplement plan, including the effective date, the premium amount, any changes in the plan, and the number of months covered by the plan. Once the information is entered into the form, it will calculate the amount of refund due to the individual or couple.
