A spousal discount of $15 per member, per month may be available. Eligibility for the spousal discount requires two members to reside at the same physical address and be enrolled on any combination of Asuris Medicare Supplement (Medigap) plan effective 6/2010 or later, such as a 2010 Standard Medicare Supplement (Medigap) plan. Furthermore, you must be either a married couple or state-registered domestic partners. The spousal premium discount will be removed if the spouse or state-registered domestic partner no longer resides with them, except in the case of their death.
