When Can I Switch To Medicare? 
I believe what you 're asking is , while you have group or an individual health plan now , when are you eligible to go on Medicare . People are eligible for premium-free Medicare Part A when they turn 65 and have met the 40 quarters -LRB- 10 years -RRB- of working life/paying FICA taxes . Anyone who is eligible for premium-free Part A , can qualify for Part B - Part B requires premiums . Younger individuals with certain disabilities who have been entitled to social security disability benefits and those with end-stage renal disease , may also be eligible to receive Medicare benefits .
