THIS IS A GOOD IDEA: New rules would force drugmakers to disclose their prices.

The Trump administration is moving ahead with a proposal that would require drug companies to include the sticker prices of their products in direct-to-consumer advertising — a controversial part of President Trump’s blueprint for lower drug prices.

Between the lines: As simple and straightforward as price disclosures might sound, this information may not end up being very useful. Few patients pay the sticker price for a drug. Their insurance plans negotiate discounts, and then often pay only a fraction of that amount.

Driving the news: The White House budget office is reviewing a proposed rule on “drug price transparency.”

• Two sources familiar with the proposal said it would implement Trump’s call to require pricing information in consumer-focused advertising. One of those sources said it would be drugs’ list prices.
