Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 92504 covers

An otolaryngologist typically uses a binocular microscope to inspect the external ear canal and tympanic membrane in an office or other clinical setting. Magnification can help assess findings such as canal inflammation, debris, a suspected perforation, or the position of a tympanostomy tube. The service is a diagnostic examination, not simply the use of a microscope as a visual aid during another procedure.

Select this code when the clinician performs and documents a distinct microscopic ear assessment. Record the ear or ears examined, the relevant findings, and how the examination informs the clinical assessment or plan. Routine otoscopy alone does not support this service, and microscope use solely to perform cerumen removal or another procedure should not be treated as a separate diagnostic examination. CMS physician fee schedule valuation accounts for work, practice expense, and malpractice inputs, with practice expense values differing between office and facility settings.
