Sandy -

If you're on a UnitedHealthcare PPO through work - your's or your husband's - it couldn't hurt to put in a call to the employer's Employee Benefits Dept., where they may have some leverage either through their broker or an in-house rep at UHC assigned to their account. They should at least be willing to take the time to read any studies or the like that you can fax into them.

Good luck!
