If you are a regular customer, pay you bills, are responsible if insurance does not pay.
They have no reason to say no. If so change doctors.
You should get extensively tested at least every three months. I have no problems getting, test, estro, and even Growth Hormone levels. Sometimes they have to check with the Doctor. My insurance pays most. Insurane even pays for weekly test shot.
