Are you finding yourself buried in denied Optical Coherence Tomography (OCT) claims despite providing excellent patient care? You’re not alone. With the recent updates in ophthalmology codes, many billers and practices are facing the same issue.
That’s why we have created this detailed guide on CPT code 92134, which is used to bill a frequently performed OCT procedure. In this guide, we will explain what this code is and how you can use it effectively in your claims.
So, let’s start.
CPT Code 92134 – Description
CPT code 92134 represents computerized ophthalmic diagnostic imaging of the posterior segment of the eye, specifically the retina. The official CPT definition states:
“Computerized ophthalmic diagnostic imaging (e.g., optical coherence tomography [OCT]), posterior segment, with interpretation and report, unilateral or bilateral; retina.”
However, it is worth noting that this is the recently updated definition. In this new definition, the American Medical Association (AMA) explicitly included “optical coherence tomography [OCT]” and removed the word “scanning.” Before 2025, the official descriptor of 92134 was:
“Scanning computerized ophthalmic diagnostic imaging, posterior segment, with interpretation and report, unilateral or bilateral; retina.”
The code represents a non-invasive procedure that creates detailed visualizations of eye structures, such as the retina, choroid, and optic nerve. An important point to note here is that CPT code 92134 is described as “unilateral or bilateral.” This means that you receive the same reimbursement whether you image one eye or both eyes during the same encounter.
Appropriate Use Cases for CPT Code 92134
To better understand CPT code 92134 and its practical usage, let’s look at a couple of real-world scenarios in which it can be used:
Age-Related Macular Degeneration (AMD)
Suppose a patient comes to an eye clinic. He complains to the ophthalmologist that he is experiencing gradual vision changes and distorted central vision. So, the physician examines the eyes in detail. During the checkup, the physician notices drusen and pigmentary changes in the macula. However, the initial checkup is not enough. For proper diagnosis, imaging is required. So, to assess the extent of age-related macular degeneration and determine whether the patient has progressed from dry to wet AMD, an OCT scan is performed.
The OCT images reveal that the retina has thickened, and there is subretinal or intraretinal fluid. Also, there are structural changes to the retinal pigment epithelium. Based on the diagnosis and the imaging results, the physician prescribes a treatment plan. In this scenario, CPT code 92134 would be billed to document the OCT imaging and its interpretation.
Retinal Detachment Evaluation
A patient presents with a sudden onset of floaters, flashes of light, and a shadow in the peripheral vision. The physician suspects a retinal tear or detachment, which requires immediate evaluation. While dilated fundus examination provides valuable information, OCT imaging can reveal subtle retinal separations and the extent of detachment that might not be visible on clinical examination alone.
So, the physician performs an OCT, which confirms his diagnosis. In this case, the OCT imaging procedure can be billed via CPT code 92134.
Modifiers to Append with CPT Code 92134
The following are the most frequently used modifiers with CPT code 92134:
| Modifier | Short Description | Usage |
|---|---|---|
| 26 | Professional Component | Used when billing only for the physician’s interpretation and report of the procedure. |
| TC | Technical Component | Used when billing only for the technical aspects of the procedure (equipment, actual imaging, technician, supplies, etc.) |
Note: Laterality modifiers RT, LT, and 50 should not be used with CPT code 92134, since it is inherently bilateral.
Reimbursement Guidelines for CPT Code 92134
The following are some essential billing guidelines that you must know before filing claims for CPT 92134:
Be Wary of the Frequency Limitations
Medicare Local Coverage Determination (LCD) guidelines impose strict frequency limits on how often you can bill CPT 92134. These limitations vary by Medicare Administrative Contractor (MAC), but general guidelines include:
- For retinal conditions (untreated): Generally, once every two months.
- Patients undergoing active intravitreal treatment: Monthly billing is typically allowed to monitor treatment response.
- For glaucoma or non-retinal conditions: Maximum of once per year.
- Overall frequency: Up to 4 times per year is typical for most retinal pathologies.
Follow the NCCI Edits & Bundling Rules
CPT code 92134 also has some bundling limitations that you must be aware of. 92134 cannot be billed on the same day as:
- 92133 (OCT of optic nerve)
- 92137 (OCT angiography)
Bundled with the modifier override option:
92134 is also bundled into 92550. However, they have an “NCCI indicator 1”. This means that they can be reported together on the same claim form in rare circumstances with modifier 59, when supported by documentation for separate payment collection.
Provide Detailed Documentation
Comprehensive documentation is your best defense against claim denials and audits.
Physician Order:
- Written or electronic order for each test.
- Date of service.
- Medically necessary diagnosis code(s).
Interpretation and Report:
- Detailed description of specific retinal findings (e.g., macular thickness measurements, presence of fluid, structural abnormalities).
- Assessment of disease severity, stage, or progression.
- Clear explanation of how the OCT findings impact patient management decisions.
- Comparison to previous imaging when applicable.
Technical Requirements:
- Permanent storage of all images.
- Patient identification on every image.
- Date and time stamp.
- Provider credentials.
Verify the Medicare Reimbursement Rate
The national average reimbursement amount for 92134 in 2026 is $32.73 for both non-facility and facility settings.
The following is a more detailed breakdown of the cost structure:
- Professional component:
- Facility price: $17.70
- Non-facility price: $17.70
- Technical component:
- Facility price: $15.03
- Non-facility price: $15.03

Final Thoughts on CPT Code 92134
That’s it! We have reached the end of our guide on CPT code 92134. 92134 is an important ophthalmology billing code that represents an OCT imaging procedure of the eye. For proper reimbursement, you must provide detailed documentation with your claims. Also, keep in mind the billing limitations that we shared in this blog.
However, billing can be challenging even for experienced billing teams. It is better to let professionals handle your medical billing and coding operations. Many companies, such as NeuraBill, offer premium ophthalmology billing services at affordable rates.
