Are you wondering: ‘What is Highmark Insurance? Highmark is one of the largest health insurers in the United States, serving more than 6 million members across Pennsylvania, West Virginia, Delaware, and western and northeastern New York. It is an independent licensee of the Blue Cross Blue Shield Association, which is why your card may read Highmark Blue Cross Blue Shield or Highmark Blue Shield depending on where you live. If you are trying to understand what your Highmark card actually gets you, especially for treatment, this is the plain-language version.
Is Highmark Blue Cross Blue Shield?
Yes, with a nuance. Blue Cross Blue Shield is not one company; it is an association of independent, regional insurers licensed to use the Blue brands. Highmark is one of those licensees. It was formed in 1996 when Pennsylvania Blue Shield merged with Blue Cross of Western Pennsylvania, and today it operates as Highmark Blue Cross Blue Shield in western Pennsylvania and several other regions, and as Highmark Blue Shield in central Pennsylvania.
The Blue affiliation matters practically: it plugs Highmark members into the nationwide BlueCard network, which is what lets your coverage travel across state lines. We cover that fully in can you use your health insurance in another state.
Where Highmark operates
- Pennsylvania: the home market, headquartered in Pittsburgh, serving both western and central PA under different Blue brands.
- West Virginia: as Highmark Blue Cross Blue Shield West Virginia.
- Delaware: as Highmark Blue Cross Blue Shield Delaware.
- New York: in western and northeastern New York.
Highmark’s parent organization, Highmark Health, also operates the Allegheny Health Network hospital system in western Pennsylvania, which makes Highmark both an insurer and part of a larger health enterprise.
The plans Highmark offers
Commercial plans
Employer-sponsored and individual plans in PPO, EPO, and HMO designs. The PPO products, including PPO Blue, carry out-of-network benefits that matter enormously for treatment choice; see Highmark PPO Blue explained for how those work.
Medicare plans
Medicare Advantage and supplement products under the Freedom Blue, Community Blue, and Security Blue names, depending on region.
Medicaid
Highmark Wholecare administers Medicaid coverage in Pennsylvania. Note that Medicaid plans work very differently from commercial PPO plans for out-of-state and out-of-network care.
What Highmark covers for treatment
Highmark is an insurance provider, not a treatment provider: it pays for care that licensed treatment centers deliver. Under the Affordable Care Act and the federal parity law, its plans cover substance use disorder and mental health services comparably to other medical care (CMS, SAMHSA). That includes medically necessary detox and inpatient rehab, covered in does insurance cover detox and inpatient rehab, and the behavioral health services detailed in does Highmark cover mental health.
For members using PPO out-of-network benefits, coverage extends to treatment centers nationwide, which is why Highmark members from Pittsburgh, Philadelphia, Wheeling, and Wilmington end up at programs in California. If that is the path you are weighing, read going to rehab out of state and why people travel to California for rehab, then let us pull your actual numbers.
Highmark and UPMC
In western Pennsylvania, members often ask how Highmark relates to UPMC. They are separate organizations: Highmark is primarily an insurer with the Allegheny Health Network on its provider side, while UPMC is primarily a health system with its own insurance arm. After years of public dispute, the two reached agreements restoring broad in-network access between their systems. What matters for you is simply what your specific plan’s network includes, which a benefits check answers in minutes.
The takeaway
Highmark is a Blue Cross Blue Shield licensee with more than 6 million members, deep Pennsylvania roots, and plan designs whose out-of-network benefits can pay for treatment far beyond its four-state footprint.
