CVS Caremark decided to stop offering one product in favor of another for weight loss, the latest example of insurance-imposed limits that disrupt treatment.

“I’m down about 50 pounds. I want to lose another 50,” Barkley said, revealing he gained 100 pounds after hip surgery. The target weight, he said, is 270 pounds. He said he is taking Zepbound, a prescription medication used for chronic weight management in adults with obesity or who are overweight.

Point32Health will dramatically change how and when it pays for Zepbound — the insurer’s preferred GLP-1 weight-loss drug— when used to treat overweight or obesity.
