Yes, also sorry for the insensitive sarcasm in the previous post. It's a chicken and egg problem. In many cases you don't know if you need a test unless you've already had it. In the case of a procedure, there may be things that come up while it's happening that may complicate things. The irony is that OPPS/IPPS (inpatient) and APC (ambulatory) are meant to simplify things. Doctors and nurses usually do their best to know ahead of time, but medical procedures are complicated.
Fraud does happen most often against medicare/medicaid (as covered in this article with one trick known as "upcoding"), but I believe these codes are used with insurance providers as well. If a hospital or doctor is in your provider network (HMO/PPO) then there is a pre-agreed cost between the two set on these fees. Out of network occurs when there is no agreement, so there is no "trust" between the two and the insurance provider offsets the cost to you because they are legally able to do so.
In my opinion - overbilling is really caused not by pricing complexity, but by the control of the hospital and insurance provider duality. If there was no such thing as a network, and you were covered everywhere, then shenanigans with certain hospitals and providers would be more difficult.

If you're getting something like a chest x-ray (posterior and lateral views), or an abdominal ultrasound, or a lipid panel, you should be able to call around to various labs with the appropriate CPT code(s) and ask them what the price would be.
What's you're talking about would be something like if they order a test and based on the result of that test, they need to perform more tests to confirm or eliminate a possible diagnosis. But for each test, you should be able to get the price since each test has a couple of possible CPT codes that it would fall under for billing purposes.
