I know nothing about billing/coding for insurance companies. But we lived in a town where the local gyne practice warned their patients to *not* bring up any problems during their routine physical exam app't. The doctors' notice explained that if you bring up a problem, the dr. needs to bill it as a sick-care visit, and that pays less than the physical--and the normal tests that are done and paid for during a physical visit WOULD NOT be covered during the "sick" visit--or something of that nature.
The gyne practice's recommendation: Come for the regular physical, and don't bring up problems. If you do have a prob., make a separate app't for that purpose.
I don't exactly understand this thinking, but perhaps something similar was going on with dh's visit; the doc may have billed for two visits in order for (possible) insurance to pay, hopefully resulting in less out-of-pocket expenses for *you* to need to pay.
Yes, I think you'll get further discussing this with the doctor than going through the business office to discuss. I'd be careful to not whine or complain; you catch more flies with honey. (i.e. Wouldn't bring up the padding her kids' college fund thing, lol. Btw, chances are that the dr. is still paying on *her* medical college loans.)
