Spend Down is calculated on a period basis. A Spend Down period is the defined length of time for which the individual can obtain coverage for Medical Assistance with Spend Down, provided that the individual meets the Spend Down amount calculated for the budget period, the length of which can vary, for example 1 or 6 months. Eligibility and the appropriate Spend Down amount must be re-determined each period. When the individual meets this Spend Down amount, they can receive Medical Assistance coverage from the date that Spend Down was met until the end of the specified Spend Down period.
