Can I Switch From Medigap To Medicare Advantage? 
Yes , If you have Medicare Part A and Medicare Part B and do not have ESRD -LRB- End Stage Renal disease -RRB- you can switch from a medigap to a medicare advantage plan during the annual open enrollment period -LRB- October 15th thru December 7th -RRB- and have a January 1st effective date . Once accepted you can then cancel your medigap and/or PDP -LRB- Prescription Drug Plan -RRB- with a January 1st termination date . I would recommend locating an independent agent who specializes in Medicare to help you thru this process ...
