The partial exemption from co-payments, the so-called excessive demand clause, applies once the load limit ( 2% the gross receipts, the chronically ill 1% ) have achieved within a calendar year. Then you can use the evidence collected (Practice fees, Co-payment for drugs, Travel costs, etc.) ask your health insurance exemption, which is valid for the remainder of the calendar year, then.
Tip! Check with your clerk your health insurance, especially low-income is the maximum load reached faster than you think.
