You may want to check this web site that list all sorts of medicals plans available in the island.

2 pieces of advice:
1) Make sure that the doctors and hospitals covered are convenient to you, some may be rather limiting.
2) If you plan to visit the mainland from time to time make sure you understand if it covers you or not In the mainland.
The most common plans used by expats in the island are Tripple S, MCS and Humana.
Triple S https://www.ssspr.com/SSSPortal Tel. (787) 774-6060

MCS health insurance

Your medicare also works just fine in the island but you may want a Medicare advantage plan which will be at little or no cost to you.
Your VA should also work in the island but some had issues being seen outside of the VA hospital, check on that.
If you meet the requirements for medicaid in the US, then maybe you can qualify for the equivalent program in PR called MiSalud (my health).
Hope this helps

PS. Because health care is lower in PR, some people do not get a health plan, that may work for you since it is cheaper, but if you end up in a bad situation with several weeks in a hospital it may drain your savings.
Also you may end up paying extra taxes if you do not have health insurance, at least for now as that requirement is still in place.
