The patient is seen as an outpatient for a bilateral mammogram. CPT Code: 77055-50 Note that the description for code 77055 is for a unilateral (one side) mammogram. 77056 is the correct code for a bilateral mammogram. Use of modifier -50 for bilateral is not appropriate when CPT code descriptions differentiate between unilateral and bilateral. 2. Physician performs a closed manipulation of a medial malleolus fracture—left ankle. CPT Code: 27766-LT The code represents an open treatment of the fracture, but the physician performed a closed manipulation. Correct code: 27762-LT 3. Surgeon performs a cystourethroscopy with dilation of a urethral stricture.
