For a normal week
Da Nang can handle ordinary care: a GP visit, a dentist, a blood test, a pharmacy for the usual things. International clinics and private hospitals sit alongside Vietnamese public hospitals. Prices are in dong. Anyone who quotes you in baht is using a template from somewhere else.
Bring your passport, a list of medicines you already take, and travel or international health insurance details if you have them. Ask the clinic whether they bill the insurer directly or whether you pay and claim. That difference matters more than the logo on the door.
Names people use
Family Medical Practice and Vinmec are the private names that come up when foreigners compare notes. They are real institutions in this city. They are not a personal recommendation until someone who lives here says which desk they would actually sit in. Public hospitals are the right place for emergencies and for a lot of specialist care. The experience is more Vietnamese, the wait can be longer, and a friend who speaks Vietnamese changes the day.
When Da Nang is not the answer
Hue Central Hospital, about two hours north, is the large public hospital for this part of the coast. People go there for serious care, not for a Tuesday check-up. Hoi An is fine for a pharmacy and a simple clinic. For anything that might need a scan, a night in hospital, or a specialist, most long-stay residents come back to Da Nang or go further.
Pharmacies are widespread and many common medicines are sold without the fuss you would meet in Britain. That is convenient. It is also a reason to know what you are buying. If you are unsure, use a clinic.
