Per WSJ, the nation's largest hospital chains, including publicly traded giants HCA Healthcare, Universal Health Services and Community Health Systems, and national nonprofit chains CommonSpirit Health and Ascension, are planing to comply with new requirements to post pricing. Tenet Healthcare declined to comment.

Within a week, hospitals will disclose prices for 300 common procedures.

This is how the system has worked for years: Hospital pricing is negotiated confidentially between hospitals and the employer groups and insurance companies that pay for care.

Many criticized this system for obscuring market rates and helping drive up the cost of health insurance premiums paid by employers and workers. Rising hospital prices accounted for about one-fifth of the nation’s health spending growth over the last 50 years.

While groups like the American Hospital Association insist that their members have responsibly shared price information related to health-care premiums and medical bills, others insist that they were long left in the dark about the potentially wide disparities charged among hospitals for the same services.

Hilariously, the AHA has claimed that the publishing of prices would "confuse" patients. Now that the issue has been settled, the organization's general counsel tells WSJ: “The AHA continues to believe that the disclosure of privately negotiated rates does nothing to help patients understand what they will actually pay for treatment and will create widespread confusion for them.”
