5 says they go with a medical savings account for drug benefits
Interestingly, you can use your FBP medical savings account for any approved health care related cost--and those are federal regulations, not company specific. I have birth control coverage in my health plan as well as a voluntary FBP account that I can then use to pay for my prescription co-pay. I save even more money that way, with copay coverage for my birth control as well as being able to use pre-tax dollars to pay that same copay.
Companies that don't offer managed FBP (medical and dependent care) are way behind the times. If I were in the market for a new job and was looking at two equal positions where the availability of FBP was present in only one, I'd take that one. With the inclusion of over the counter medical remedies to the list of approved expenditures, anyone who isn't using it is a certified idiot.
