Cesarean Section wound infection

I would appreciate any help on this scenerio. I have not had a respone to any of my questions on this site and I am getting discouraged.
We have a patient that came in one week post op from a c-section. Her wound was infected and the physician treated it with silver nitrate. What is the CPT® code for this? Will we be paid for this? Do I need to use a modifier?

It will probably be included in global period.
