Ophthalmic testing

About 92284: Diagnostic dark adaptation examination

A diagnostic dark-adaptation study evaluates recovery of visual sensitivity in darkness, typically when symptoms or findings raise concern for impaired rod function.

This examination measures how visual sensitivity recovers after the eyes move from light into darkness. Ophthalmologists and optometrists may use it when a patient reports difficulty seeing in dim conditions or when findings raise concern about retinal rod function. Testing is generally performed in an eye-care office with dark-adaptation equipment; the service includes interpretation and a report of the diagnostic findings.

Report 92284 for diagnostic testing, rather than the screening measurement represented by 92288. Documentation should identify the clinical reason for testing and include the results and interpretation. The code may be billed globally, or the professional interpretation and technical testing may be billed separately with modifiers 26 and TC. When multiple ophthalmic diagnostic procedures are performed, the Medicare multiple-procedure reduction applies to the technical component. The code is priced as bilateral, so modifier 50 does not increase payment.

92284 billing questions

When should 92284 be used instead of 92288?

Use 92284 for a diagnostic dark-adaptation examination prompted by symptoms or clinical findings. Code 92288 describes a screening dark-adaptation measurement.

Can the professional and technical services be billed separately?

Yes. Report modifier 26 for the professional interpretation and modifier TC for the technical service; billing without either modifier represents the global service.

Does modifier 50 increase payment for testing both eyes?

No. CMS prices 92284 as bilateral, and modifier 50 does not increase payment.

How does the multiple-procedure reduction affect 92284?

When multiple ophthalmic diagnostic procedures are performed, the reduction applies to the technical component of 92284.

What documentation supports reporting 92284?

The record should support the diagnostic reason for testing and contain the dark-adaptation findings and interpretation. A screening service is reported with 92288 instead.
