I had the same situation and I put both accounts on the same letter because it was from the same CA. You will have to put the different account numbers so they will be able to distinguish anyways.

Specialized Collection Services has 2 different accounts from 2 different OC's- Do I send the medical dispute letter with both accounts together- or should I send them seperately?
thanks
