Stupid rules

In order to see a specialist, my insurance requires a referral from the PCM, Primary Care Manager. In this case, our pediatrician. Now, I have to give him credit, because he has been very helpful to us - we got the referral for the psychologist from him and the referral for the Occupation Therapy eval based on the psychologists recommendation. Based on the OT recommendations, we went today to request a referral for a Physical Therapy eval and an Ortho consult. He agreed to put in the referral for the PT eval, but not the Ortho consult. He said that without a specific diagnosis attached to it, the insurance would definitely deny it.
So, we have to wait for all the paperwork to go through, probably 2 weeks, before we can even schedule the PT eval, which will then take 2-4 weeks to get in for. Then we'll have to start the whole process again for the Ortho consult.
It just seems stupid to me that one specialist can't just refer you to another specialist directly through your insurance, instead of you having to jump through 6 different hoops to get the approvals.
