St. Mary Medical Center, in Langhorne, said it will build a $20.5 million, 50-bed acute rehabilitation hospital in partnership with Centerre Healthcare Corp., of Nashville, Tenn.

The new rehabilitation facility will go up on the site of the former Neshaminy Middle School across the street from St. Mary's main campus.

When the new facility is completed next spring, St. Mary will convert its existing 31 bed rehabilitation unit into one with private rooms for patients in the main hospital, St. Mary said.

Inpatient rehabilitation is often required for victims of stroke, spinal-chord injuries, brain injuries, and other serious conditions.

Earlier this month, St. Mary said it had completed an $8.4 million expansion that added four operating rooms and finished the second phase of a $22 million renovation of its emergency department. - Harold Brubaker
