Anyone with an Anthem Blue Cross Blue Shield plan will soon have to pay out of pocket for anesthesia if a surgery or procedure goes longer than expected, according to the American Society of Anesthesiologists.

The health insurance provider said they will no longer pay for anesthesia care if a surgery or procedure goes beyond a specific time limit. This will apply to patients in Connecticut, New York and Missouri.

The American Society of Anesthesiologists said Anthem can pre-determine the time allowed for anesthesia, and if an anesthesiologist submits a bill where the actual time of care is longer than Anthem’s limit, the company will deny paying for it.
