Last week Don Ray wrote on Chiriqui Chatter about a Cardiologist who told him that Hospital Regional would no longer accept expat patients in need, that they would need to go to Santo Tomas in Panama City.
Don wrote about it, perhaps prematurely and then contacted the US Embassy to obtain verification.

The response from the US Embassy was what I knew from a conversation with another Cardiologist who also works in Regional. This rumor was false.
The embassy response is also on Chiriqui Chatter, http://www.chiriquichatter.net/blog/2015/05/15/s-o-l-post-updated/
Bottom line yes you do need to pay for medical care at Regional but unlike a private hospital they will admit you, treat you and work a=out a payment plan with you.
