Quick Answers
What is CPT 92083?
It is the extended, full-threshold visual field exam that maps the entire field of vision point by point, the most detailed of the three visual field codes and the standard test for tracking glaucoma and neurological vision loss.
How do you bill it for both eyes?
As a single unit, no matter how many eyes are tested. The descriptor already reads unilateral or bilateral, so skip the -50, RT, and LT modifiers; a second unit reads as duplicate billing.
What keeps a 92083 claim clean?
A justifying ICD-10 such as glaucoma or a visual field defect, a signed interpretation on file, and testing kept within the payer’s frequency limit. Medicare pays roughly $63.80 in 2026.
What Is CPT Code 92083?
CPT code 92083 is an extended visual field examination that maps a patient’s full field of vision using threshold automated perimetry, such as a Humphrey 24-2 or 30-2. It is the most detailed of the three visual field codes and the standard test for monitoring glaucoma and neurological vision loss, billed once per session whether one eye or both eyes are tested.
- One code, both eyes: 92083 is inherently unilateral or bilateral, so you bill a single unit even when both eyes are tested. It does not take a -50, RT, or LT modifier.
- 2026 Medicare rate: Medicare pays about $63.80 for 92083 in 2026, and the rate is the same in office and hospital settings because the cost is driven by the testing equipment.
- Medical necessity is everything: The claim needs a documented reason to test, a signed interpretation and report, and an ICD-10 code such as glaucoma or a visual field defect that justifies the exam.
New to ophthalmology billing? Start with our ophthalmology medical billing overview, then use this guide for the specifics of CPT 92083. Visual field testing is a workhorse of any glaucoma-heavy practice, and 92083 is the code that carries the most clinical and financial weight. Across the ophthalmology practices we match with billing partners, it is one of the highest-volume diagnostic codes and also one of the most commonly miscoded, usually because the exam level or the diagnosis link does not hold up on review.
What Does CPT 92083 Cover?
CPT 92083 reports an extended, or threshold, visual field examination. The American Medical Association defines it as a visual field examination, unilateral or bilateral, with interpretation and report, extended examination, using either Goldmann visual fields with at least three isopters plotted and static determination within the central 30 degrees, or quantitative automated threshold perimetry such as Humphrey full-threshold programs 30-2, 24-2, or 30/60-2. In plain terms, it is the most thorough visual field test, mapping the full field point by point rather than screening a few locations.
That level of detail is why 92083 is the gold standard for monitoring glaucoma progression and for evaluating neurological vision loss. Common program types billed under 92083 include the automated 24-2, 30-2, and 10-2, along with Goldmann kinetic perimetry. The code covers the test itself plus the physician’s interpretation and a signed report, and it is used more than 2.2 million times a year in Medicare alone, which tells you how central it is to eye care and how closely payers watch it.
One point worth flagging up front: the AMA revised the descriptions for 92081, 92082, and 92083 in 2024, so any coding reference or cheat sheet built before then may be out of date. The current descriptors are what payers adjudicate against, and using an old one is a quiet way to land on the wrong exam level.
92081 vs 92082 vs 92083: Choosing the Right Visual Field Code
There are three visual field codes, and they form a ladder by the depth of the exam. Picking the right rung is the single most important coding decision for this service, because billing a higher level than the test supports is a classic audit trigger, and billing a lower level than you performed leaves money on the table.
| Code | Exam Level | Example Tests | Typical Use |
|---|---|---|---|
| 92081 | Limited | Tangent screen, single stimulus automated test | Basic screening as part of a broader workup |
| 92082 | Intermediate | At least 2 isopters on Goldmann, suprathreshold screening | More detailed screening, mid-level evaluation |
| 92083 | Extended | Threshold automated 24-2, 30-2, 10-2; Goldmann 3+ isopters | Glaucoma monitoring and neuro-ophthalmic workup |
The most common issue we see providers run into is defaulting to 92082 out of caution when the test actually run was a full threshold 24-2 or 30-2, which is 92083. If the perimeter produced a full point-by-point threshold map, the extended code is the correct and defensible choice. There is also a bundling rule to know: under the National Correct Coding Initiative, the visual field codes are mutually exclusive with one another. If you perform a 92082 and, based on the results, go on to run a 92083 the same day, you bill only the higher-value code, 92083, not both. You cannot stack two levels of the same visual field service on one date.
How Do You Bill 92083 for Both Eyes?
You bill 92083 once, as a single unit, whether you test one eye or both. The code descriptor reads unilateral or bilateral, so the payment already covers testing both eyes. Do not report two units, and do not append a -50, RT, or LT modifier to split it by eye. Medicare and most payers assume the test is performed on both eyes.
This trips up practices that think of visual fields as a per-eye service the way some other ophthalmic tests are billed. It is not. Reporting 92083 twice for a bilateral exam is a duplicate-billing error that will be denied or recouped. A more serious version of the same mistake is testing one eye today and the fellow eye a week later specifically to bill the code twice. That is fragmentation, and payers treat deliberate fragmentation as fraud, not a coding quirk.
Where laterality and modifiers do come in is the technical and professional split. When the practice owns the perimeter and the physician interprets the result, you bill 92083 globally. When one entity performs the test and another interprets it, the interpreting physician bills 92083 with modifier 26 for the professional component and the facility bills modifier TC for the technical component. A handful of payers maintain their own laterality rules, so it is always worth confirming an unusual payer policy before you submit.
If visual field claims are bouncing and you are not sure whether it is the exam level, the modifiers, or the diagnosis link, a billing partner who lives in ophthalmology will spot the pattern fast. Get matched with vetted billing companies that know 92083 inside out, compare them side by side, and see who fits your practice, at no cost to you.
How Much Does CPT 92083 Pay in 2026?
Medicare pays approximately $63.80 for CPT 92083 in 2026 under the national Physician Fee Schedule. Unlike most codes, the rate is the same whether the test is done in an office or a hospital outpatient setting, because the cost is driven by the perimeter and its interpretation rather than by the place of service.
| Detail | 2026 Figure | Note |
|---|---|---|
| Medicare national rate | ~$63.80 | Same in office and facility (equipment-driven) |
| Work RVU | ~0.50 | Reflects the interpretation and report component |
| 2026 conversion factor | $33.4009 | Applied to total RVUs to set the national rate |
| Average provider charge | ~$147.34 | Roughly a 2.3x markup over the Medicare allowable |
Local Medicare Administrative Contractor pricing adjusts the national figure by regional wage index, and commercial payers set their own allowables, so the number on your remittance will vary. The gap between the average charge near $147 and the Medicare allowable near $64 is normal and reflects the difference between billed charges and contracted rates. The practical takeaway for revenue is that 92083 is a modest per-click code whose value comes from volume and clean adjudication, which is exactly why frequency limits and documentation matter so much for it.
Medical Necessity and ICD-10 Pairing for 92083
A visual field test only pays when the diagnosis explains why it was needed. For 92083, that means pairing the CPT code with an ICD-10 code that establishes medical necessity, most often glaucoma, a glaucoma suspect finding, or a documented visual field defect. Across the billing companies we vet, the ophthalmology specialists build this diagnosis-to-test link as an automatic claim-scrubbing rule rather than a manual check, because a missing or mismatched diagnosis is one of the top reasons 92083 denies.
| ICD-10 Code | Description |
|---|---|
| H40.9 | Unspecified glaucoma |
| H40.003 | Preglaucoma, unspecified, bilateral (glaucoma suspect) |
| H53.40 | Unspecified visual field defects |
| H53.431 | Sector or arcuate defects, right eye |
| H53.413 | Scotoma involving central area, bilateral |
Two coding details matter here. First, the specific glaucoma type codes, such as the primary open-angle glaucoma family H40.11-, require a seventh character for the glaucoma stage, so those codes are not complete until you add the stage digit. Second, coverage frequency is governed by Local Coverage Determinations, and for a stable glaucoma patient many payers expect roughly one visual field per year. Testing more often than the clinical picture supports invites a frequency denial even when the code and diagnosis are correct. Beyond the diagnosis link, the record has to carry a clear reason for the test tied to signs or symptoms, the reliability indices from the perimeter, the physician’s interpretation, a signed report, and the treatment decision the result drove.
Common 92083 Denials and How to Avoid Them
Providers often come to us after a run of visual field denials they could not pin down, and the causes are usually a short, familiar list. Working through these before submission catches most of them:
- Wrong exam level: Billing 92083 when the test performed was a limited or intermediate field, or the reverse. Code to the test the perimeter actually ran.
- Billing per eye: Reporting two units or adding RT and LT for a bilateral exam. Bill one unit of 92083 for both eyes.
- Weak diagnosis link: Submitting without an ICD-10 code that justifies the test. Pair 92083 with glaucoma, a glaucoma suspect code, or a visual field defect.
- Missing interpretation or report: Claiming the test with no signed interpretation on file. Document and sign the report before billing.
- Frequency overruns: Testing a stable patient more often than the payer’s LCD allows. Match testing intervals to the clinical picture.
- Same-day conflicts: Stacking 92082 and 92083, or pairing with a test the local policy excludes on the same day. Bill only the higher visual field code.
None of these are clinical problems. They are coding and documentation habits, and a billing operation that specializes in ophthalmology builds the checks into claim scrubbing so the fix happens before a denial, not after.

Frequently Asked Questions
CPT 92083 is used for an extended, threshold visual field examination, such as a Humphrey 24-2 or 30-2. It is the most detailed of the three visual field codes and is the standard test for monitoring glaucoma progression and evaluating neurological causes of vision loss, including the interpretation and a signed report.
92082 is an intermediate visual field exam, such as suprathreshold screening or at least two isopters on Goldmann. 92083 is an extended, full-threshold exam that maps the field point by point, like a 24-2 or 30-2. If both are done the same day, only 92083 is billed because they are mutually exclusive.
Yes, but only as one unit. The 92083 descriptor is unilateral or bilateral, so a single unit already covers testing both eyes. Do not report two units and do not add a -50, RT, or LT modifier. Billing it twice for a bilateral exam is a duplicate-billing error.
Frequency is set by Local Coverage Determinations, not a single national rule. For a stable glaucoma patient, many payers expect about one visual field per year, with more frequent testing supported when the disease is progressing or unstable. Testing beyond what the clinical picture justifies risks a frequency denial.
Not for laterality. It never takes -50, RT, or LT. Modifiers apply only to the technical and professional split: modifier 26 for the interpreting physician’s professional component and TC for the technical component when the test and the interpretation are billed by different entities.
Common supporting diagnoses include glaucoma (for example H40.9), glaucoma suspect or preglaucoma (such as H40.003), and visual field defects (such as H53.40, H53.431, or H53.413). Specific glaucoma-type codes like the H40.11- family also require a seventh character for the glaucoma stage.
The usual causes are the wrong exam level, billing per eye instead of one unit, a weak or missing ICD-10 link, a missing signed interpretation and report, exceeding the payer’s frequency limit, or a same-day conflict with another visual field code. Most are preventable with pre-submission claim scrubbing.
