What 92311 covers

92311 covers contact lens fitting for one aphakic eye, meaning the eye lacks its natural crystalline lens. A typical situation is aphakia after cataract removal when no intraocular lens was placed; congenital aphakia is another possible cause. An ophthalmologist or optometrist selects the lens characteristics, evaluates fit and visual effect, and oversees the patient’s adaptation. The service may include trial-lens assessment and instruction in lens handling, usually in an eye-care office.

Report 92311 for fitting one eye. When both aphakic eyes are fitted, 92312 is the bilateral sibling rather than two units of 92311. Documentation should identify the eye and support the aphakic diagnosis, fitting performed, and lens characteristics selected. Distinguish a fitting from a routine fitting for an eye without aphakia, a technician-performed fitting, or a later lens adjustment or replacement. CMS values the service using physician work, practice expense, and malpractice inputs; the practice-expense inputs differ between office and facility settings.

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.

92311 billing questions

When should 92311 be used instead of 92312?

Use 92311 when the fitting is for one aphakic eye. Use 92312 when both aphakic eyes are fitted; do not report two units of 92311 for that bilateral fitting.

How should the record identify the eye?

Document which eye is aphakic and being fitted, along with the fitting work and selected lens characteristics. The code represents one eye.

Is this the code for fitting a contact lens in a nonaphakic eye?

No. For a standard corneal contact lens fitting in an eye without aphakia, consider 92310; 92311 is specific to aphakia in one eye.

Does 92311 describe lens modification or replacement?

No. Code 92325 describes modification of an existing contact lens, while 92326 describes replacement; 92311 is for the aphakic fitting service.

How does 92311 differ from 92315?

Both concern fitting for aphakia in one eye. 92315 is the technician-performed fitting code; 92311 describes the fitting service with medical oversight of adaptation.

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.
