Subject:	Tenet Healthcare files lawsuit against Community Health Systems

Earlier this morning, Tenet filed a lawsuit against Community Health Systems (“CHS”) alleging that for many years CHS has systematically overbilled Medicare and likely other payers as well. CHS has done this by causing patients to be admitted to its hospitals unnecessarily when, under standard clinical practice, these patients should have been treated in outpatient observation status. CHS’ strategy of converting emergency room visits to medically unnecessary inpatient admissions has, we believe, overstated CHS’ admissions statistics and trends, revenues, profits and cash flow, and has created substantial undisclosed liabilities to Federal and State healthcare programs, private health insurers and patients.

We discovered this admissions strategy as a result of due diligence we conducted while evaluating CHS’ unsolicited proposal to purchase Tenet. The data and analysis contained in our complaint have been compiled and verified by independent industry consultants. The litigation we filed today seeks to compel CHS to fully and accurately disclose the risks and financial impact of its admissions strategy, and to prevent CHS from issuing further misleading statements.

Clearly, the allegations our lawsuit makes are serious, and neither I, nor our Board of Directors, took lightly the decision to file this lawsuit. But once we learned of these facts, we concluded that it was in the best interest of Tenet’s shareholders and other constituencies to bring this lawsuit. If you would like to read the complaint or related materials, please click here (insert hyperlink).

The Board and I believe strongly in the merits of our claims, and we have an excellent team dedicated to this matter. Please do not let today’s action distract you from your normal course of business. It is imperative that we continue doing what we do best; that is, provide quality healthcare to our patients, or for corporate employees, it means supporting our hospitals in that mission.

As always, I thank you for your ongoing commitment to Tenet and I will continue to update you on the CHS situation as warranted.
