Which hosp ur friend go lar? Usually pharmacist section doesn't know can claim or not. Not their job

Insurance and private hospital are not your friend.
My last trip for appendicitis removal, I got to wait until my appendix burst and rush into op room. 1 or 2 day stay become 7 days all because of a late GL from insurance.

My take - - > life is more important than to worry about a small medicine bill that you have to pay. If its a small sum, just pay and move on. My last visit cost be a whopping 20k++ & regardless how I hate insurance comp, without it will be dent to my wallet (over the last 5 years I have been in and out of hosp 3 times, a total of RM75k.
Learn from that, and move on.
