Conclusion
You should note that your age, as the working spouse, will affect when your non-working spouse qualifies for premium-free Medicare Part A. You are required to be at least 62 years old and eligible for Social security [8] benefits before your spouse can enroll, this is because his or her eligibility to enroll for the plan is based on your work record. In conclusion, spouses should think about the above options before making insurance decisions. You can also consult your insurance companies for more information.
