I used to have my scans at a private clinic in Sosua that didnt accept insurance so for a checkup and regular scan, it was like 800 pesos.
When i go to my doctor in Puerto Plata now, that accepts insurance, the same costs me like 300 pesos with insurance or like 1300 without.
It does depend on the doctor though. Id love to see a pricelist as sometimes it feels like they go, hmmmmmm, thats 1000 pesos please.
Ive had scans in 4 different places in sosua and puerto plata and never had a bad experience. Well, one was poorer quality but the docs have always been professional.
