For the other 20 percent, it’s best to go to a private clinic, where the care is as good if not better than many US clinics but at 10-20 percent of the cost.
And the private clinics are not subsidized.
My wife just got an MRI at a private, fully for profit imaging clinic. The total cost was $217 USD for a study with and without contrast on a 2023 Siemens scanner. Labs for the contrast approval were $6.
What people pay in the USA is in no way justified by equipment or facility costs. Runaway liability and profiteering, perhaps. But not because of the “quality” of the healthcare or the equipment.
