What 92137 covers
This service uses optical coherence tomography angiography to create images of blood flow in the posterior eye, including retinal and choroidal vascular structures. Ophthalmologists commonly use it when evaluating retinal vascular conditions such as diabetic retinopathy, macular degeneration, or retinal vein occlusion. The test is performed in an eye-care setting with specialized imaging equipment, and the interpreting clinician provides a report.
Report the service for the OCT angiography study, whether one or both eyes are imaged. The record should identify the clinical reason for testing and include the resulting interpretation and report. The code may be billed globally or split into professional and technical components: modifier 26 identifies interpretation, and modifier TC identifies equipment and staff. The ophthalmology diagnostic multiple procedure reduction applies to the technical component. The code is already priced as bilateral, so modifier 50 does not increase payment.

92137 billing questions
How is 92137 different from 92134?
92137 describes OCT angiography, which depicts blood flow in posterior-segment vessels. 92134 is used for structural retinal imaging with retinal thickness analysis.
Can the service be billed for both eyes?
Yes. The code is priced as bilateral, and modifier 50 does not increase payment.
When should modifier 26 or TC be used?
Use modifier 26 for the professional interpretation and report, or modifier TC for the equipment and staff portion. Billing without either modifier represents the global service.
Does the multiple procedure reduction affect both components?
The ophthalmology diagnostic multiple procedure reduction applies to the technical component.
What documentation supports reporting 92137?
Document the reason for OCT angiography, the posterior-segment imaging performed, and the interpreting clinician’s findings and report.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
