All the Federated States have good government hospitals in the main cities. There are also dental services and private health clinics throughout the islands. Be aware that doctors and hospitals may ask for cash payment for health services. Scuba-divers are advised there are only three decompression chambers in the Federated States (Yap, Pohnpei and Chuuk). Their availability varies and there is very little experience in treating dive injuries. Health insurance is highly recommended. Certain emergency cases are referred to Hawaii and Guam.
