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

What 92133 covers

This test uses computerized scanning, most often optical coherence tomography, to assess the optic nerve head and retinal nerve fiber layer thickness; it may also assess macular ganglion cells. Ophthalmologists and optometrists use it in office and hospital outpatient eye clinics for glaucoma suspects, established glaucoma, ocular hypertension, and optic neuropathies. A technician captures the scans, and the interpreting clinician evaluates their quality and findings, comparing results with prior studies when available.

Report one unit whether one or both eyes are scanned. The code is already priced as bilateral, so modifier 50 does not increase payment. Document an interpretation and report with findings relevant to the optic nerve assessment. Billing without a modifier represents the global service; append modifier 26 when billing only the interpretation or TC when billing only equipment and staff services. When multiple eligible ophthalmic diagnostic tests are performed, Medicare's ophthalmic diagnostic multiple procedure reduction affects lower-valued technical components, not the professional interpretations. Use a different code when retinal or macular imaging is the clinical focus.
