Since the standardization of the Medicare supplement insurance plans in 1992 these plans are sold and administered by the private health insurance companies only. But since then there had been only twelve Medigap health insurance plans to be sold by the private health insurance companies. And till date there had been no change in the standard Medigap health insurance plans. But by June 2010 some major changes are coming up in the standard Medigap plans. These changes include the suspension of four of the existing Medigap plans. Other than that two new plans M and N are going to be introduced. With the introduction of these two plans the beneficiaries of the Medicare supplement insurance would be more benefited. These two plans using the cost sharing and the deductibles would cut down several Medicare premium costs. Thus it is hoped that these two plays would be much popular with the beneficiaries. Therefore it is always recommended to choose the Medicare supplement health insurance plans very carefully.
