Having worked in the medical field for many decades, I have personally dealt with dozens of health care insurance companies and medical plans. United healthcare is the scum-of-the-earth. Poison! Literally, dealing with UHC is like dealing with organized crime. We're in South Florida, a location in which UHC has more than 20 different lines of insurance. Physicians' offices are fleeing UHC like rats from a sinking ship. The reason: UHC cheats, steals, and conducts themselves in a disgusting manner. Our office, long ago, quit/disenrolled as contracted "providers" with UHC (Reason: We got tired of all of the dishonest conduct. They were absolutely impossible to "work with"). More recently, UHC acquired a "good plan" that we do participate in. Now, in a few short months, this health plan is awful -- doctors, patients, and anyone else that I've spoken to hates it. Example: The surgical practice than I'm in knows all too well exactly how to submit any/all documentation for surgery preapproval/preauthorization -- we now have dozens of claims, for 100% fully preauthorized surgeries, in which (after the surgery) UHC "denies" the claim and does not pay-the-contracted-rate for the bill, and instead requests "documentation" (i. E. the EXACT SAME documentation that had already been submitted before the surgery, in order to get a preauthorization). It's shocking to me that this type of willful, criminal conduct is tolerated and sanctioned. UHC should not be allowed to conduct business in the State of Florida. Their pattern of abusive conduct is nothing short of willful organized crime. (Note: I certainly would have "rated" UHC as "ZERO Stars" but it was necessary to fill-in at least One Star to submit this completely honest and accurate review).
