After announcing their intention to merge in April, WellSpan Health and Summit Health have officially signed an affiliation agreement.
York-based WellSpan announced Friday that both nonprofit organizations have approved the deal, which still requires regulatory approval and could be completed in a few months. Terms of the deal were not disclosed.
Under the proposed affiliation, Chambersburg-based Summit would become part of the York County-based WellSpan network, which has been expanding throughout Central Pennsylvania over the last five years.
Summit operates two hospitals, in Chambersburg and Waynesboro, and a range of medical offices, walk-in care centers and other services in Franklin County. It has about 3,600 employees.
Based in York Township, WellSpan operates six hospitals, a multispecialty medical group and a range of other providers at more than 140 patient-care locations. It has more than 15,000 employees.
The merger will extend WellSpan’s territory from Lancaster and Lebanon counties in the east to Franklin County in the west. It will be serving roughly 1 million people. WellSpan already partners with Summit on a regional reference lab and a behavioral health managed care organization. The two systems also collaborate on radiation oncology, neurology, tele-stroke and perinatology services.
The union with Summit Health would be the fourth affiliation for WellSpan in the past five years.
WellSpan moved into Lancaster County in 2013 through an affiliation with Ephrata Community Hospital, now known as WellSpan Ephrata Community Hospital.
That was followed by an affiliation with Good Samaritan Health System in Lebanon County. Good Samaritan Hospital became WellSpan Good Samaritan Hospital.
In 2015, WellSpan announced it was pursuing an affiliation with Philhaven, a Lebanon County-based behavioral health agency. It now operates as WellSpan Philhaven.
Meanwhile, other providers and insurers around the region also have been busy creating partnerships.
Insurer Highmark Health and Penn State Health were the most recent, unveiling a relationship in December. The partnership is currently planning a new West Shore hospital.
Before that, it was Pittsburgh-based UPMC and Harrisburg-based PinnacleHealth. Pinnacle, now operating as UPMC Pinnacle, absorbed four midstate hospitals from Tennessee-based Community Health Systems Inc.
Lancaster General Health, meanwhile, joined the University of Pennsylvania Health System in 2015.
