Ophthalmic diagnostic imaging
About 92133: Optic nerve scanning imaging with interpretation
Scanning laser or OCT imaging of the optic nerve head and retinal nerve fiber layer, reported mainly for glaucoma diagnosis and monitoring.
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.

92133 billing questions
Should one unit or two be billed when both eyes are scanned?
Bill one unit. The code covers unilateral or bilateral imaging, and because it is priced as bilateral, modifier 50 or a second unit does not add payment.
Can optic nerve OCT and retina OCT be billed on the same day?
CPT instructs that 92133 and 92134 are not reported together at the same patient encounter. Choose the code matching the structure that was the clinical focus, such as optic nerve for glaucoma or macula for diabetic macular edema.
When is modifier 26 or TC appended?
Use 26 when billing only the interpretation and TC when billing only the equipment and staff portion. A practice that provides both portions bills the global code without a modifier.
Does the multiple procedure reduction affect 92133 when visual fields are done the same day?
Medicare's ophthalmic diagnostic multiple procedure reduction applies to lower-valued technical components when multiple eligible tests, such as 92133 and 92083, are performed. It does not reduce their professional components.
What documentation supports the interpretation?
Document a written interpretation of scan quality and relevant optic nerve or nerve fiber layer findings, with comparison to prior scans when available. An image printout alone does not establish the professional interpretation.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
