What 92083 covers

Extended visual field testing maps peripheral and central sensitivity with automated quantitative threshold perimetry, commonly on Humphrey or Octopus equipment using 24-2, 30-2, or 10-2 patterns. Qualifying Goldmann kinetic testing plots at least three isopters and checks static points within the central 30 degrees. A technician administers the test in an eye clinic or hospital outpatient department; an ophthalmologist or optometrist interprets reliability, defect patterns, and changes from prior fields. Common indications include glaucoma surveillance, optic neuropathy, chiasmal lesions, and hydroxychloroquine toxicity monitoring.

Select 92083 for a documented extended strategy rather than intermediate suprathreshold testing or limited screening. Record the strategy, eye or eyes tested, reliability, results, and clinical interpretation. Report one unit whether one or both eyes are tested: CMS prices the code as bilateral, and modifier 50 does not increase payment. Modifier 26 identifies interpretation only; modifier TC identifies equipment and staff only. Bill without a component modifier when both portions are provided. When performed with other eligible ophthalmic diagnostic tests, the ophthalmology diagnostic multiple procedure reduction affects eligible technical components.

92083 billing questions

How is this code distinguished from 92082 and 92081?

The level depends on the testing strategy, not the time spent. Quantitative threshold programs, or Goldmann mapping with at least three isopters and central static testing, support 92083. Suprathreshold testing or qualifying two-isopter mapping supports 92082; limited methods support 92081.

Should modifier 50 be added when both eyes are tested?

Report one unit whether one or both eyes are tested. CMS already prices 92083 as bilateral, so modifier 50 does not increase payment.

When are modifiers 26 and TC used?

Use modifier 26 when billing only the interpretation, such as reading fields performed in a hospital outpatient department. Use modifier TC when billing only the equipment and technician portion. A practice billing both portions reports the code without either component modifier.

Can it be billed on the same day as an eye exam or OCT?

Yes, when the extended field test is performed, medically necessary, and documented. It may accompany an ophthalmic exam or optic nerve imaging; the ophthalmology diagnostic multiple procedure reduction affects eligible technical components of same-day diagnostic tests.

What documentation supports the interpretation?

A signed interpretation should identify the test strategy, eyes tested, reliability, findings, and comparison with prior fields when available. A test printout alone does not support billing the professional component.

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.
