In March 2026, “it's always a challenge to get paid by insurance, and especially nowadays, it's becoming more and more complicated. The payer rules are constantly changing. There are more prior authorization requirements. More denials are happening. Claims are getting rejected. Systems are more fragmented, so it's just harder to get paid by insurance for the services that you've already rendered. And there are a lot of reasons why that is, but I think we're just seeing mass frustration across the board from most physicians and providers in the industry,” said Roshan Patel, founder and CEO of a health care payments company.
