Wendell Morris stopped recently at a Rite Aid drugstore in Santa Monica to get a flu shot.
A worker at the pharmacy said Morris' insurer, Anthem Blue Cross, didn't cover flu shots. So Morris paid about $30 out of pocket for the vaccination.
He later saw the column I wrote last week about how drugstores may be misleading people about flu-shot coverage. He called Anthem to ask whether his insurance covered the vaccine. It did.
Morris, 48, returned to Rite Aid and showed them my column. The drugstore manager, he said, immediately refunded the money he'd paid for the flu shot.
"They obviously seemed to know this was an issue," Morris told me.
"You want to trust drugstores," he said. "Now it seems like we have to check first with our insurance company and tell the drugstores that we know we have coverage."
I received hundreds of emails in response to that column. Almost all related experiences similar to what Morris went through, involving all leading drugstore chains and insurance companies.
The common denominator to all these emails was the consumer being told by the drugstore that his or her insurance didn't cover flu shots and being asked to pay about $30 — in some cases, as much as $50 — for the vaccine.
Each customer's insurer subsequently confirmed that coverage existed.
"It seems like more than just honest mistakes on the drugstores' part," said Joel Hay, a professor of pharmaceutical economics at USC. "It wouldn't surprise me if something nefarious was going on."
He cited last week's news that Kmart will pay $2.55 million to settle complaints that it overbilled government health programs for prescription drugs. This shows that pharmacies can behave less than honorably, Hay said.
"If they know for a fact that a person has insurance coverage and they're not applying it, that's fraud," he said.
Insurers may be complicating things by an inconsistent approach to offering drug benefits. In some cases, the coverage may be listed as a "pharmacy benefit." In others, it may be classified as a "medical benefit."
Drugstore workers thus may run a customer's insurance card through the system seeking coverage of flu shots as a pharmacy benefit, and may overlook that the coverage is provided as a medical benefit.
Greg Schapansky, a pharmacist in Northern California, said it makes no sense that insurers seem to have such a hard time classifying flu shots.
"This season, I have seen more than one company deny pharmacy billing at retail pharmacies and call flu shots a medical benefit," he said. "Why would this be necessary? Why would it matter as long as their insured gets immunized?"
Good question. Then there's the question of why a drugstore might want to mislead customers about whether their insurance covers flu shots.
Turns out there's serious money to be made by such behavior.
