Billionaire entrepreneur Mark Cuban is seemingly taking aim at the U.S. healthcare system every day, and this time, he questioned why insurance companies can deny medical care without facing the same level of accountability that doctors and hospitals often do.
“If insurance companies can deny care and call it ‘medically unnecessary,’” Cuban wrote in a recent post on X, “why aren’t they required to have malpractice insurance when they get it wrong and someone gets sicker or tragically dies?”

To Cuban, one of the biggest problems is the lack of transparency in healthcare pricing. Instead of hospitals posting bundled procedure prices, he proposed showing the actual costs of supplies, labor and treatment materials used for each patient.
“Show the actual cost the hospital paid for the bandaids, the sterile water, the fully burdened with benefits doctor, nurse, [physical therapist], and anything else that is used specifically for the care of that patient,” he wrote. Insurance bureaucracy dramatically inflates healthcare spending through billing disputes, administrative costs and pricing manipulation.

Cuban also said that insurance companies should largely be removed from routine healthcare payments altogether because insurance-related administration and billing disputes add massive costs to the healthcare system.
He estimated the current roughly $5 trillion U.S. healthcare system could potentially shrink to around $2.5 trillion if the industry became more transparent and less dependent on insurance-related …
