Established patient comes to the office complaining of migraine headaches, Physician performs an expanded problem focused history and exam. The Physician's medical decision making is of low complexity. During the office visit, the Physician also removes a benign 0.5 cm lesion from the back of the patient's left hand. My code is 99213-57/11420. I made this choice because the decision based on the exam and history, but the Physician also made a decision to remove lesion not recorded in the original Chief Complaint. Am I correct, or should I remove the 57 modifier?
Physician removes a foreign body from the anterior chamber of the patient's eye. An allergy statement in the patient's medical records indicates that the patient is allergic to local anesthesia, as a result general anesthesia is administered - my code 99222/65235-47, because the Physician administered the anesthesia himself, there is no mention of anesthesia services administered by an AA, MDA or CRNA. Did I use modifier 47 correctly?
