If you can afford it, get health insurance, but the rates are higher the older you are, and if your over 60 they go through the roof, that's if they will insure you.

Be aware that many doctors here, who will charge you in excess of the regular charge as a "skin tax" as we are perceived to be able to afford it.

Also hospitals will add on extra's not necessary, ie, they always insist on a drip, but it only contains saline solution. Extras like artificial limbs are difficult to have maintained here, its only in Manila or Cebu where there are facilities to have these repaired or replaced, but the quality and expertise is poorer, usually using 2nd hand appliances from abroad. In Manila there is a private house where European standards are maintained, but it is the most expensive you will encounter.

Local Emergency hospitals are normally for maternity so no xray's just a bed and a couple of nurse. Broken arms etc are transferred to nearest public hospital, but their conditions are very, very 3rd world and you could wait for hours to be attended. Also you must have cash up front before anything is done ie, xrays etc.

Private hospitals are faster and better conditions, but are expensive, and again cash or credit card is necessary up front. You will not be allowed to leave the hospital until full payment is made. Locals can leave after signing promissory notes. This is breaking the law, but hospitals still carry on this practice regardless.

Also doctors here carry drugs given by reps' they will sell you these, and also try to sell drugs that are not available from the drugs store. These are expensive, and I suspect some are ersatz. If you are unfortunate to be involved in an accident, they will send you to the nearest hospital, if you are not coherent, they will not treat you until a family member comes up with the payment details. You could die while waiting, but that is not their concern.

The doctors Hippocratic oath only applies in the Philippines if you can pay for the services, doctors says they did this as its an investment to a comfortable life. The standards of their training is not so good either, that's why when they go abroad to work its usually as nurses, but only after they did some retraining.
