I worked in claims previously, and that isn't really how it works.
With the company I worked for, an appraiser was sent out to assess the damage to the vehicle, or we had an app that the claimant could send pictures to in order to figure out how much damage there was. The alternative was the person could go to one of the "recommended" shops. Some of the recommended shops were actual dealerships, so I'd send people there usually for the most accurate estimate. It also took less time than waiting for the appraiser. The recommended shops were usually trusted by the insurance company to do the appraisal. Usually we would cut the person a check and it was up to them to decide what shop they wanted to go to.
The insurance company does this because they know if shops hear "insurance is paying for it" the price somehow doubles.
