That is not my understanding. According to Publication 969, a limited purpose FSA may only be used for the following categories of expenses:
- Liabilities incurred under workers' compensation laws, tort liabilities, or liabilities related to ownership or use of property.
- A specific disease or illness.
- A fixed amount per day (or other period) of hospitalization.
- Accidents.
- Disability.
- Dental care.
- Vision care.
- Long-term care.
Further, the specific allowable uses of your FSA should be particular to your plan's documents. As an example, my limited-purpose FSA may only be used for vision & dental care.
It is possible that I am mistaken, but I haven't read anything similar to what the two of you have seen. (I would actually be happy if there was such an exemption!)
