What 92136 covers

Optical biometry uses partial coherence interferometry or similar optical technology to measure axial length without touching the eye. Devices may also capture keratometry, anterior chamber depth, and other dimensions used in intraocular lens calculations. An ophthalmic technician or assistant typically acquires the measurements in an eye clinic or outpatient department. The ophthalmologist interprets the results and calculates lens power for a patient preparing for cataract surgery or refractive lens exchange.

Report 92136 when optical biometry includes an intraocular lens power calculation. Retain the measurements, the calculated lens power, and the interpreting clinician’s report; record the formula and other inputs used when available. Modifier TC identifies the equipment-and-staff portion, and modifier 26 identifies the interpretation and calculation portion. Billing without either modifier represents the global service. CMS prices the code as bilateral, so modifier 50 does not increase payment; measuring the second eye alone does not support another technical unit. The ophthalmology diagnostic multiple procedure reduction applies to the technical component when this test is billed with other eligible diagnostic tests.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

92136 billing questions

When is 76519 reported instead of 92136?

Report 76519 when ultrasound A-scan biometry provides the measurements and an intraocular lens power calculation. An optical reading may be unobtainable with a dense cataract or poor fixation.

Can modifier 50 be appended when both eyes are measured?

Modifier 50 does not increase payment because CMS already prices 92136 as bilateral. Measurements of both eyes in one session do not justify a second technical unit.

How do modifiers 26 and TC split the service?

Modifier TC identifies the equipment-and-staff portion; modifier 26 identifies the professional interpretation and lens power calculation. Bill the applicable component when reporting only that portion, or report the global service when billing both together.

Does a multiple procedure reduction apply when OCT is done the same day?

The ophthalmology diagnostic multiple procedure reduction applies to the technical component of eligible tests performed on the same date, which may include 92136 with retinal OCT. It does not reduce the professional component under this rule.

What documentation supports billing 92136?

Keep the optical biometry measurements, the intraocular lens power calculation, and the interpreting clinician’s report. Document the calculation inputs, such as keratometry and the formula used, when available.

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.
