Blue Cross Blue Shield

Blue Cross Blue Shield is not one company. Understanding that is the single most useful thing a shopper can know about it, because it explains both the network depth and the state-to-state inconsistency.

Where the company came from

The Blues began as a hospital experiment. In 1929, an administrator named Justin Ford Kimball at Baylor University Hospital in Dallas set up an arrangement where local schoolteachers prepaid a small monthly amount in exchange for a set number of hospital days. It was a response to the plain fact that teachers could not pay hospital bills and the hospital could not collect them. The model spread, and by the mid-1930s prepaid hospital plans were operating across the country under the Blue Cross name.

Blue Shield came later and from the other side of the bill. Physician service plans — beginning with California Physicians' Service in 1939 — did for doctor care what Blue Cross had done for hospital care. The two systems ran in parallel for decades before merging their national associations in 1982.

What survived that history is the structure. Blue Cross Blue Shield today is a federation of independent, locally operated companies, each licensed to use the Blue marks in its own territory. Florida Blue, Highmark in Pennsylvania, and Blue Cross Blue Shield of Texas are separate companies with separate plan designs, separate networks and separate service operations. They are linked nationally through the BlueCard program, which is what lets a member get in-network care while traveling.

What it does well

Hospital network depth

In most regions the local Blue plan has the deepest bench of contracted hospital systems. If there is one hospital your family would insist on, the Blues are usually the first place to check.

National reach through BlueCard

The card travels. For families split across states, employees who relocate, or students away at school, this is often the deciding factor.

Local operating knowledge

Because each plan is run locally, the company understands regional provider dynamics in a way national carriers sometimes do not.

Long provider relationships

Decades of contracting history tends to mean stable networks and fewer mid-year contract blowups, though no carrier is immune to them.

What to watch for

How to tell whether it fits you

Carrier reputation is close to useless as a selection criterion. What matters is whether this specific plan, with this specific network, covers the providers you actually use. Before you enrol with Blue Cross Blue Shield or anyone else:

• Verify every doctor on your list against the plan’s current directory — and if it matters enough, call the practice and ask them directly. Published directories go stale.
• Look up each prescription on the plan’s formulary and note the tier.
• Read the Summary of Benefits and Coverage before enrolling, not after.
• Check whether the family deductible is embedded or aggregate.
• Confirm the out-of-pocket maximum, in network and out, per person and per family.
