Juan Perez, who is turning age 65 next month, intends to work for several more years at Smallcap, Incorporated. Smallcap has a workforce of 15 employees and offers employer-sponsored healthcare coverage. Juan is a naturalized citizen and has contributed to the Medicare system for over 20 years. Juan asks you if he will be entitled to Medicare and if he enrolls how that will impact his employer-sponsored healthcare coverage. How would you respond?

a. Juan is likely to be eligible for Medicare once he turns age 65 and if he enrolls Medicare would become the primary payor of his healthcare claims and Smallcap does not have to continue to offer him coverage comparable to those under age 65 under its employer-sponsored group health plan.
b. Juan is likely to be eligible for Medicare once he turns age 65 and if he enrolls his employer-sponsored coverage would continue to be the primary payor while Medicare would be considered a secondary payor of his healthcare claims.
c. Juan is likely to be eligible for Medicare once he turns age 65 and if he enrolls Medicare would become the primary payor of his healthcare claims but Smallcap must continue to offer him coverage under its employer-sponsored group health plan and would become a secondary payor.
d. Juan is likely to be ineligible for Medicare since he was born outside the United States and has only contributed to the Medicare system for 20 years.
