UNH & atrius health (In my region at least) tends to control outpatient lab costs by going with capitated service agreements with large labs. Paying a fixed amount / life covered for all outpatient studies including AP. In NE they could care less what the 88305 charge is for outpatients it is baked into the lab contract. On the CP side they keep a close eye on blood tests to contain costs & within atrius the PCPs are employed so they are easy to control. I don’t think AP is as closely monitored b/c the real spend is on the CP side.
