As far as I recall, Medicare pricing is defined by law as a percentage of the lowest price the provider ever charges to anyone else. For the sake of this comment, call it 40%.
If Medicare pricing is public, you can look it up and try to negotiate for 250% or whatever of the Medicare price.
What you're sharing is great information and a fine foundation for people to build on. But pateients shouldn't have to go off and do a pile of research, they should be able to get a straight answer from their health provider when they ask for one.
If you have a pet and have to visit the vet, you already know they prefer to get paid up front. They'll generally tell you there's a fixed fee for the consultation/ Then depending on what's wrong with your animal they offer a treatment estimate, which is prepared within minutes and about which the administrative staff are generally competent to answer questions (eg why there might be variations in price for some items like anaesthetic). Animal medicine is at once less complex than human medicine (narrower range of treatment options, fewer administrative/legal considerations) and more complex (considerable variation among species).
I've been to good vets and bad vets, but the administrative aspects of both regular and emergency care have been painless and yes, transparent. Until we get universal healthcare, veterinary service would be an excellent model to imitate.
Regarding pets, they are not beholden to hospital/insurance provider duality, and it follows that since it is out of pocket, you would not be able to afford a $60k set of procedure if your dog had a broken leg...so the prices stay affordable.

You seem to be talking about medicare and medicaid, and not about private hospital services. Is that correct?
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.
There are several systems, but let's take a look at Outpatient procedure pricing...
A good outpatient pricing guide is here: https://www.cms.gov/Outreach-and-Education/Medicare-Learning...
And coupled with the OPPS dataset here: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Paymen... as well as a couple others, along with a quick read of the federal register, you can kinda figure it out on your own (/s).
Every bill you get must also have the codes and modifiers on it by law. Its interesting to download the dataset and look them up.
--EDIT-- I incorrectly linked to the COBOL PC Pricer code above for OPPS! Here is the pricing data: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Paymen...
