Visual field testing is one of the most effective ways to detect changes in peripheral vision. Sometimes you can spot them even before the patient notices. The most basic stage of a visual field examination is aligned with CPT code 92081, which is a limited procedure code. For new patients, people without known visual field problems, and those who need initial checks, this test sets a good baseline. Understanding how this code works in your practice will help you bill correctly and provide the right level of patient care at the right time.

Summary

• CPT 92081 is used for screening visual field exams, especially when there is no prior abnormality or clinical indication. It’s billable to most payors, including Medicare.
• Virtual Field makes it possible to conduct screenings in your practice or off-site so that you can offer complete vision screenings almost anywhere.
• Proper documentation and following our step-by-step billing workflow can help you maximize reimbursement and minimize denials.

What This Code Covers

The American Medical Association defines CPT® 92081 as:

Visual field examination, unilateral or bilateral, with interpretation and report; limited examination (EG, tangent screen, autoplot, arc perimeter, or single stimulus level automated test, such as Octopus 3 or 7 equivalent).

This definition means that it is a routine screening visual field examination that usually includes automated perimetry and one isopter. You’ll often use this code for a peripheral vision test that functions as a wellness check. This test is used for general screenings, not for patients with a specific diagnosis. For more in-depth testing or to screen specifically for glaucoma, CPT 92082 or 92083 may be more appropriate.

CPT code 92081 typically includes these visual field tests:

• C-40
• N-30
• Superior 36
• Frequency doubling technology (FDT)

As part of a comprehensive eye exam, visual field testing at this level serves as a first-stage screening for conditions such as glaucoma, macular degeneration, retinopathy, neurological conditions, or ptosis. This limited exam can then provide enough information to decide if further testing is warranted.

For example, if you had a patient with a family history of glaucoma but no noticeable changes to their vision, you could incorporate this test into an annual screening. If there are abnormalities, you would then have evident justification to follow up with a more comprehensive visual field test (like CPT 92082 or 92083). Running a CPT 92081 visual field screening with Virtual Field allows you to quickly check their peripheral vision and detect these subtle changes early.

When and Why to Use Code 92081 with Virtual Field

Just like traditional tabletop perimeters, you can use Virtual Field to conduct a 92081 visual field examination for routine comprehensive screenings and follow-ups.

Standardized testing and immediate data integration make it much easier to document and bill for this code. Virtual Field automatically guides patients through the exam, captures data consistently, and uploads results directly into the electronic health record (EHR).

Virtual Field’s flexible and portable headset helps you see patients almost anywhere. You can complete screenings in your practice, at a facility, or even at a connected telehealth setup. This way, you can provide initial screenings to more patients and establish a baseline for care.

Eligibility and Clinical Indications

By definition, your patients do not need a diagnosis to complete this test. In fact, some payors require a lack of diagnosis, but they do require medical necessity. Medicare, however, doesn’t cover preventive vision testing, so it needs a clinical indication, even if it’s nonspecific or based on risk factors. This justification could be as simple as the patient having risk factors for glaucoma.

92081 is a basic, limited screening that helps you achieve an initial diagnosis or follow up on known conditions. A glaucoma suspect, someone with a family history of glaucoma, or a patient with nonspecific ocular or neurological complaints would be ideal for this exam, since this screening can help you determine if thorough testing is necessary.

Most commercial insurers will allow 92081 when used as a screening tool that’s appropriate for the patient. Always check your coverage policies and local coverage determinations (LCDs).

‍

Documentation Checklist

Even though Virtual Field simplifies testing and collects reliable information, you still need to meet documentation visual field test requirements. This means noting the reason for the exam, including a brief relevant medical history, attaching the automated test results, and writing a summary. Make sure the visual field interpretation and report are signed and filed in the chart. Clear documentation is your best protection against claim denials and ensures that the exam is counted as a legitimate, reimbursable service.

CPT 92081 Documentation Checklist

• Reason for screening (routine, risk factor, preventive)
• Patient history (brief ocular or systemic relevant history)
• Visual field results (automated output)
• Interpretation statement by the ophthalmologist or optometrist
• Signed report stored in the patient's chart

‍

Step-by-Step Billing Workflow

Follow these simple steps to conduct the 92081 correctly and bill appropriately.

Step 1: Order the Test

Before conducting an automated visual field test, you must order this test as part of the comprehensive screening. Be sure that the patient is appropriately asymptomatic and you’re not using 92081 as an intermediate or advanced diagnostic tool.

Step 2: Technician Performance

Conduct the automated test, making sure the patient is comfortable and compliant. Virtual Field will automatically guide the patient through the exam and document reliability indices.

Step 3: Physician Interpretation

Review the test results, document your interpretation, and confirm the report. Don’t forget to sign the report in the patient’s chart and store it securely.

Step 4: Claim Submission

Submit the claim using CPT 92081. Include any necessary modifiers and the ICD-10 diagnosis code that justifies the screening. Accurate use of modifiers is one of the easiest ways to avoid denials when billing visual field tests.

Relevant modifiers include:

• -26: Professional Component
• -TC: Technical Component
• -LT: Left Side
• -RT: Right Side

Reimbursement and RVU Snapshot

The national average fee and RVUs (relative value units) for CPT 92081 are set by CMS (the Centers for Medicare & Medicaid Services). They are maintained in the Medicare Physician Fee Schedule (MPFS). These numbers can vary by region and by payor, so check for updates annually.

As of September 2025, the global period is zero days, meaning there are no bundled post-care limitations. Depending on location, setting, and modifiers, CPT code 92081 is currently reimbursable between $32 and $42. The current wRVU per unit is 0.30.

‍

Common Denial Reasons and How to Avoid Them

Even in the best circumstances, claims denials can still happen. Thankfully, most are avoidable.

Incorrect Modifiers

Visual field codes are bilateral by default. Don’t bill separate lines with LT/RT modifiers unless absolutely necessary, and watch out for missing or incorrect modifiers.

Payor-Specific LCD Limitations

LCDs define what Medicare considers “reasonable and necessary” for diagnosis or treatment. 92081 may be denied if prior visual field testing exists or if a symptomatic patient actually requires an advanced test, such as 92083.

Documentation Gaps

Omitting the patient’s history, reason for the screening (even when it’s just a limited exam), or missing interpretation details can trigger denials. These steps are easy to overlook, but are very likely to flag claims.
