As a foreigner & traveller I would not recommend this hospital, please visit VinMec.
We visited VK Hospital before attending VinMec, and this was not very clean nor were they able to diagnose the problem, long waiting times and completed a procedure which 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 reception was extremely rude and only accepted cash. Equipment was dated, the ancient hospital and English was very limited.
Go to VinMec instead.
