I work for a wound care clinic that happens to also offer Hyperbarics treatment to patient with non healing diabetics wound, cosmetic abdominoplasty, hypospadias etc. Now I would like to know if the provider is able to bill and E/M code on every routine wound care visit. For example, patient comes for wound debridement on the same wound that has once been evaluated in the past. I ran into an article that stated that if the patient is coming for routine wound care on the same wound that only the debridement is to billed. But if the patient shows up with a new wound or ulcer that codes 99211-99215 are able to billed along with the modifier 25 and the debridement.
