Date to meet with my pcm

I called today and set up my appointment with our pcm and the only time they could get me in to see them was on the 23rd of the month of course they had one earlier appointment for next tuesday but my husband has surgery that day in Raleigh so I couldn't take it but oh well I'm just happy that I don't have to wait a month or more to see someone, my husband said I could go in for sick call tomorrow and they would have to work me in but I just don't know if I should, I mean I'm not sick so should I do it??? but I did some research online and found a meeting for lap band for Thursday in Raleigh and since we will already be there because of my husbands doctors appointment I thought it would be good and then I can put that in my file and when they turn everything into tricare I would have a great chance of getting approved right ????
