With a law as complex as the Patient Protection and Affordable Care Act (PPACA), unintended consequences are always a concern. Last week The Wall Street Journal reported that the physician community is witnessing the emergence of a significant unintended consequence -- since tax-advantaged flexible spending accounts can no longer be used to pay for over-the-counter medications without a prescription, under the law, many patients are now visiting their doctors expressly for the purpose of getting new prescriptions for the OTC medications. The change in the law was meant to discourage wasteful spending on some health products and raise revenue. Instead, critics say the provision is driving up health care costs.
