A patient had a cyst removal on her back, this was done by dermatology office. Patient comes to our office (family practice/different doctor) to have the sutures removed. patient did not want to return to dermatology to have them removed. What primary dx code do I use to code the site of the cyst? I know V58.32 is secondary.. but I'm not sure if this would be coded under "wound/back.. 876.0 " We do not have any documentation yet from the dermatology office.
