There are more than 2,000 hospitals in this country that admit Medicare-eligible patients. Now that the 2010 Patient Protection and Affordable Care Act has been declared constitutional by the U.S. Supreme Court, penalties set to begin in October will be levied on those hospitals that readmit patients with the same condition within a 30 day period.

Earlier this week, we outlined the Medicare reimbursement cuts that are coming to area hospitals. Now it's time to look at how the hundreds of facilities owned by locally based hospital chains will be affected. In many cases, they won't face any cuts, but across the board, the impact will be felt. (A caveat: The CMS data at the root of our data doesn't cover every single hospital owned by local companies.)

Among the highlights you'll find in our data, which is available here:

• Facilities owned by Ardent Health Services will incur the lowest average penalty, while those owned by LifePoint Hospitals are in line for the biggest average cut.

• Thirty-three facilities owned by the companies listed will see their reimbursements cut 1 by percent. Fourteen of those are owned by CHS, another 10 by LifePoint.

• Eighty-two hospitals will face no cuts come October. HCA owns 33 of them; CHS, 24.
