Doctor saw a patient with a painful umbilical mass. Patient is scheduled for an excision of the umbilical mass. I have an ICD 10 (R19.05) but can not find a CPT code. His notes read "patient was advised that we would proceed with an infra umbilical incision with eversion of the umbilicus and resection of the mass. There might be a need to remove some surrounding tissue if a fistulous tract is found or a cystic lesion." Any help would be appreciated.
