Pre op weigh in

Hi everyone my surgery is scheduled for sept 20th. I haven't started the pre op diet yet but i see my surgeon on sept 4th. Per my insurance empire bc/bs i have to be one pound less than the weight i was in march. In March i was 240 now im 243. Is it possible that the insurance or surgeon will deny me. Covid has been rough stopped alcohol and marijuana and have been low carb for the last 5 weeks.
