Mrs Smith Presented to Her Physician's Office for an Office

Mrs. Smith presented to her physician's office for an office visit for an upper respiratory infection. The physician examines the patient and prescribes antibiotics. The physician notices the patient has a suspicious-looking mole. The physician examined the mole and determined that it should be removed. The mole was removed during the same office visit. The physician bills both an E/M code and a procedure code. Which modifier would you use on the E/M code? ____________________
