                     HCA Previews First Quarter 2006 Results

Nashville, Tenn., April 17, 2006 --- HCA (NYSE: HCA) announced today it expects
financial results for the quarter ended March 31, 2006 to be between $0.89 to
$0.93 per diluted share compared to $0.95 per diluted share in the first quarter
of 2005. Financial results for the first quarter of 2006 include gains on sales
of investments related to securities held by the Company's wholly-owned
insurance subsidiary of $75 million, or $0.11 per diluted share, compared to
gains of $9 million, or $0.01 per diluted share, in the first quarter of 2005.
The first quarter 2006 results also include additional compensation costs of $8
million, or $0.02 per diluted share, due to the expensing of stock options and
employee stock purchase plan shares associated with the January 1, 2006 adoption
of FASB Statement 123 (R), "Share-Based Payment."

The Company expects to report revenues of $6.415 billion for the first quarter
of 2006, compared to $6.182 billion in the same period of 2005. Same facility
revenues increased 5.0 percent, and same facility revenue per equivalent
admission increased 5.1 percent in the first quarter of 2006 (7.4 percent
increase when adjusted for uninsured discounts) compared to the previous year's
first quarter.

Preliminary volume statistics indicate that same facility equivalent admissions
decreased 0.1 percent and same facility admissions decreased 0.7 percent
compared to the prior year's first quarter. Volumes were weaker than anticipated
in certain markets, including those in Florida and Virginia. Flu-related
pulmonary admissions decreased by approximately 5,000 admissions, or 10.5
percent, compared to the prior year's first quarter. During the quarter,
inpatient surgeries grew 2.3 percent and outpatient surgeries increased 1.0
percent compared to the prior year's first quarter.

The provision for doubtful accounts in the first quarter of 2006 is expected to
approximate $596 million, or 9.3 percent of revenues, compared to $574 million,
or 9.3 percent of revenues, in the first quarter of 2005. Adjusted to reflect
uninsured discounts, in the first quarter of 2006 the provision of doubtful
accounts totaled approximately $852 million, or 12.8 percent of revenues,
compared with $683 million, or 10.9 percent of revenues in the first quarter of
2005. Uninsured discounts in the first quarter of 2006 were $256 million and
$109 million in the first


                                       -1



quarter of 2005. The Company's uninsured discount policy, which became effective
in the first quarter of 2005, lowers revenues and the provision for doubtful
accounts by generally corresponding amounts. Charity care totaled $281 million
in the first quarter of 2006 compared to $284 million in the previous year's
period. Same facility uninsured admissions (including charity patients)
increased by 2,438 admissions, or 13.1 percent, in the first quarter of 2006
compared to the first quarter of 2005.

HCA plans to report complete results for the first quarter on April 25, 2006 and
any update to previously issued earnings guidance for 2006 will be provided at
that time. HCA will hold a conference call and web-cast to discuss the first
quarter results on April 25, 2006.
