More than half of physicians who responded to a recent survey (52 percent) noted they have a patient who encounters coverage issues because of inaccurate payer directories every single month.

The inaccuracies have prompted a regulatory response. The Centers for Medicare & Medicaid Services and state legislative bodies have issued regulations to ensure physician directory accuracy across the industry. Additionally, there is substantial variability among state rules.

My latest at AMA Wire. The whole shebang.
