YAG for Epithelial Ingrowth
Question: My physician uses a YAG laser to treat epithelial ingrowth on a patient. Would we bill the YAG procedure code of 66821 and the diagnosis of H18.891? Or should we be using the unlisted code 66999?
Answer: CPT 66821 is not appropriate as the descriptor indicates it is for secondary cataract.
Consider CPT 65450 Destruction of lesion of cornea by cryotherapy, photocoagulation or thermocauterization.
