         The consolidated financial results for the nine months ended September
30, 2001 reflect a 17.6% increase in admissions, and a 17.0% increase in
adjusted admissions, compared with the nine months ended September 30, 2000. On
a same store basis, net operating revenues for the nine months ended September
30, 2001 increased 11.0%, admissions increased 4.6%, and adjusted admissions
increased 4.3% compared with the nine months ended September 30, 2000.

          The 13.8% and 36.6% increases in the weighted average number of shares
(diluted) outstanding for the third quarter and the nine months, respectively,
ended September 30, 2001, compared to the same periods of 2000 are due
principally to the Company's initial public offering in June 2000 and a
secondary public offering in November 2000.

         "Our outstanding financial and operating performance during the third
quarter of 2001 reflects continued momentum from our strategy of centralization
and standardization as we again exceeded expectations," commented Wayne T.
Smith, chairman, president and chief executive officer of Community Health
Systems, Inc.

         Since September 1, 2001, the Company completed three acquisitions, each
of which is the sole provider of general hospital services in its community.
These newly acquired hospitals are Red Bud Regional Hospital (103 beds) in Red
Bud, IL; Jennersville Regional Hospital (59 beds) in West Grove, PA; and Easton
Hospital (369 beds) in Easton, PA. Each of these facilities had previously been
owned by a tax-exempt entity.

         On October 9, 2001, the Company completed a public offering of 12
million shares of common stock and the sale of $287.5 million of 4 1/4%
convertible subordinated notes, due October 2008, including the exercise of the
notes over-allotment. Net proceeds from these offerings of approximately $585
million were used to pay off $500 million of 7 1/2% subordinated debt plus
accrued interest and the remainder used to repay other long-term debt under the
Company's credit agreement.

         "During the third quarter we closed on one additional hospital and
since that time have acquired two more bringing the total to four during 2001.
The acquisition of these facilities continues to demonstrate the success of the
Company's focused non-urban acquisition strategy. Furthermore, with the
completion of our additional financing, the Company is well positioned to pursue
our strategic objectives by providing us with an even stronger capital
structure," Smith concluded.

         Community Health Systems, Inc., a leading provider of non-urban acute
healthcare services, currently owns or operates 56 hospitals across 20 states.
These facilities, together with their medical staffs, provide a wide range of
inpatient and outpatient acute care services and a variety of specialty
services.

         Community Health Systems, Inc. will hold a conference call to discuss
this press release on Thursday, October 25, 2001 at 10:30 a.m. CDT, 11:30 a.m.
EDT. Investors will have the opportunity to listen to a live broadcast of the
