Allegheny Health Network
medical system in Western Pennsylvania
Allegheny Health Network (AHN), based in Pittsburgh, is a non-profit, 16-hospital academic medical system with facilities located in Western Pennsylvania and one hospital in Western New York. AHN was formed in 2013 when Highmark Inc., a Pennsylvania-based Blue Cross Blue Shield insurance carrier, purchased the assets of the West Penn Allegheny Health System (WPAHS) and added three more hospitals to its provider division. Allegheny Health Network was formed to act as the parent company to the WPAHS hospitals and its affiliate hospitals. Highmark Health today serves as the ultimate parent of AHN.
Today, AHN consists of an academic hospital and transplant center (AHN Allegheny General Hospital in Pittsburgh, the network's flagship), six tertiary-care hospitals, five community hospitals, and four "neighborhood hospitals." The network cares for patients from western Pennsylvania and the adjacent regions of Ohio, West Virginia, New York and Maryland at more than 250 clinical locations, including six “Health + Wellness Pavilions,” cancer clinics, surgical centers, outpatient clinics, and primary care locations.
The system includes the AHN Research Institute, the Allegheny Clinic, a home health and infusion company, a group-purchasing organization, LifeFlight, and the STAR Center, which provides simulation training for medical, nursing, and other health care professionals. The network operates two nursing schools, and serves as a clinical campus for the medical schools of Duquesne University, Drexel University and Lake Erie College of Osteopathic Medicine. AHN also operates one of the nation's largest graduate medical education programs, and its teaching hospitals annually train about 500 medical residents and fellows in 48 accredited programs and specialties.
As of 2026, AHN employs approximately 27,000 people, with over 3,000 employed and affiliated physicians, plus 2,000 volunteers. In 2025, AHN's facilities admitted and / or observed 130,000 patients, logged 400,000 emergency room visits, recorded 4.1 million physician visits, and delivered 8,700 babies.

Why this record matters
“Allegheny Health Network” is worth following because a concise public description often conceals a longer documentary argument. Here, Allegheny, Health and Network provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 9, 2026. The linked authority identifier is Q7986183. 2 of 4 selected statements include explicit references; 3 carry qualifiers and 1 use preferred rank. The first chronological checks are 2013, 2026 and 2025.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
