What 92004 covers

A comprehensive new-patient eye evaluation includes the patient's history, general medical observation, external and ophthalmoscopic examinations, gross visual fields, and a basic sensorimotor examination. Slit lamp examination, tonometry, and dilation may be performed when indicated. The ophthalmologist or optometrist initiates a diagnostic or treatment plan based on the findings. The service is commonly performed in an office but may also be performed in a facility.

Report 92004 when the patient meets the new-patient definition and the documented service meets the comprehensive examination requirements rather than those for an intermediate examination. A patient is new if no professional service was received from the physician or another physician of the same specialty in the same group during the preceding three years. The evaluation may take one or more visits; report the completed service once. Record the examination findings and plan, and support the medical necessity of the visit. Refraction, when performed, is separately reported. Medicare prices 92004 as bilateral, so modifier 50 does not increase payment.

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.

92004 billing questions

When should 92004 be chosen over 92002?

Choose 92004 when the documented new-patient service meets the comprehensive examination requirements, including ophthalmoscopy and initiation of a diagnostic or treatment plan. Choose 92002 for an intermediate new-patient examination.

Is refraction included in 92004?

No. When performed and documented, determination of refractive state is reported separately with 92015. Medicare generally excludes refraction from coverage.

Should modifier 50 or RT/LT be appended?

Do not append modifier 50 to seek bilateral payment: 92004 is already priced as bilateral. An RT or LT modifier does not create a second payable eye examination.

Can 92004 and a new-patient E/M code be billed on the same day?

Do not report both for the same evaluation by the same provider. Select the code that describes the documented encounter; a genuinely separate E/M service requires its own supporting documentation and must meet applicable billing rules.

What if the comprehensive exam takes two visits?

The comprehensive service may span more than one visit, such as when a patient returns to complete the examination. Report 92004 once when the service is complete.

Are dilation and tonometry billed separately?

No. Dilation and tonometry performed as part of the comprehensive examination are not separately reported. A distinct diagnostic test, such as medically necessary visual field testing, may be reported separately when performed.

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.
