I used the microscope to examine both ears during an office visit because the middle ear Otoscopic exam was abnormal. Can I report 92504 with modifier 50 (bilateral procedures)?
No. CPT 92504 describes using a microscope for an examination – it represents payment for using a separate piece of equipment for your exam. The code is not reported twice, nor is modifier 50 appended, when both ears are examined.
