As a foreigner & traveller, I would not recommend this hospital; please visit VinMec.
We visited VK Hospital before attending VinMec, which was not very clean, nor were they able to diagnose the problem, long waiting times and completed a procedure that did not fix the issue.
Dr also asked for a tip and confirmed he had no idea what was wrong - after he did the procedure.
The receptionist was extremely rude and only accepted cash. Equipment was dated, and the ancient hospital and English were minimal.
Go to VinMec instead.
