Wiki Questions on Depo-Medrol solution and Hemovac Drain

[BrettAAPC]

I am new to neurosurgery coding, and I have spotted on a few surgeries the application of a Hemovac Drain in which the surgeon "laid a Hemovac Drain into the epidural space, brought it out through a separate stab incision and went on thereafter to close the wound in the usual way."

Does anyone know if there is a code that covers this sort of device?

Also, for another surgery, the application of a Depo-Medrol solution was applied to the nerve, can this be billed out as a code?

Thanks for your help,

Brett
