Dr. John Sutter, a pediatrician, agreed with a number of other physicians to provide medical care for individuals insured with Oxford Health Plans. Oxford agreed to pay the physicians according to the terms of a contract all the physicians signed. The contract provided for arbitration of any disputes between Oxford and the physicians. Dr. Sutter was not paid in a timely fashion and filed an arbitration claim. However, other physicians wished to join him in the claim for a sort of class action arbitration. Is that possible under arbitration? Who should make that decision about allowing other doctors to join in on the claim of lack of timely payment?
