That question is one that's bounced around since Wal-Mart announced it would offer prescription drugs for as low as $4 per 30-day supply.

The plan, which will be available to the general public (including customers without insurance), has lead to some speculation that insurers will see a serious drop in individual health insurance policies.

Furthermore, it seems as if a new consumer-driven health market could drive up the popularity of health savings accounts. In a recent press release, HSA for America President, Wiley Long, pointed out that health insurance plans with $15 prescription drug co-pays don't make a lot of sense when you can get you're medications for under one Abe Lincoln a pop.

On the other hand, HSAs would give consumers a way to save for future medical expenses, the assets of which would grow tax-free. If consumers can handle higher deductible, says Long, HSAs could be a great solution for millions of Americans. Currently, deductibles start around $1,000.

"The higher deductible can take a little getting used to for people who are accustomed to low co-pays for prescription drugs and doctor visits," admits Long, "but when you consider that premiums are 30 to 40% less than traditional co-pay plans, it really makes a lot of sense."

Long also estimates that inquiries about HSAs have grown by 20 percent since Wal-Mart's announcement.

Realizing that press releases are, in fact, used to get press, I do think that HSAs will continue to grow in popularity, especially as the health market continues to sway in favor of consumers. So what will that do to the individual health insurance market?

Predictions, anyone?
