PuzzleMedicare Supplement plans, (sometimes called Medigap plans), are insurance policies that include standardized sets of benefits offered by private health insurance companies that pay the portion of healthcare expenses that is not paid by Original Medicare.  If you have Original Medicare, and you enroll in a Medicare Supplement plan, Medicare will pay it’s share of approved amount for health care costs that it covers and the Medicare Supplement plan will then cover its share of the costs.

Ten Standardized Plans

Private insurance companies that offer Medicare Supplement plans, offer a standardized package of benefits and cannot create plans that vary from these standardized plans.  In most states (excluding MN, MA and WI) these Ten standardized plans are identified by letters A, B, C, D, F, G, K, L, M, and N.  The the excluded states listed above, plans are standardized in a slightly different way.

The standardization of plans makes it easy to compare similar plans offered by different insurance companies.

For example ‘Plan A’ offered by Mutual of Omaha will  offer identical benefits to ‘Plan A’ offered by Cigna, and in both cases, members can use any doctor that accepts Medicare payments.  The only difference between the two policies would be the monthly premium and the insurance company providing the underlying benefits.

* Plan F also offers a high-deductible option in some states.  Plan F high-deductible requires you to pay for Medicare-covered costs (coinsurance, copayments, and deductibles) up to the deductible amount of $2,180 during the calendar year before your Medicare Supplement policy pays anything.

** Plan N pays 100% of the Part B coinsurance, except for a copayment of up to $20 for some office visits and up to a $50 copayment for emergency room visits that don’t result in an inpatient admission.
