Question 1: I am currently on state disability in California and receiving medi-cal benefits. Do i need to reapply during open enrollment if i have no change in my situation? In other words will my coverage continue if i do nothing?
Question 2: i will be 62 in october and am applying for social security retirement. Do i need to enroll for medicare before feb 15?
Medicaid can require re-enrollment to prove you are still eligible. Contact your state Medicaid department. While you won't have to re-enroll in Medicaid during open enrollment. You can re-apply or re-enroll at any time of the year. Usually you'll be prompted to "re-prove" your eligibility.
For your other question. Medicare initial enrollment starts three months before you turn 65. You'll need to have other coverage until then. You can cancel your private plan so it ends when Medicare coverage starts when it comes to that point.
