What 92312 covers

An ophthalmologist or optometrist uses this code when fitting contact lenses for a patient who is aphakic in both eyes, such as after removal of the crystalline lenses. The service involves assessing the eyes and visual needs, selecting lens characteristics, evaluating fit and vision, and supervising the patient’s adaptation. It is a clinical fitting service, not a report for the contact lenses themselves.

Report 92312 when the fitting addresses aphakia in both eyes; use the unilateral sibling when only one eye is fitted for aphakia. Documentation should identify the aphakia, both eyes, the fitting work performed, lens specifications selected, and the clinical assessment of fit or adaptation. CMS prices this code as bilateral, so report it once for both eyes; 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.

92312 billing questions

Should 92312 be reported once or once for each eye?

Report 92312 once for a bilateral aphakia fitting. CMS prices the code as bilateral, and modifier 50 does not increase payment.

When is 92311 a better choice?

Use 92311 when the aphakia contact lens fitting is for one eye. 92312 describes the fitting for both eyes.

How does 92312 differ from 92310?

92312 is for fitting contact lenses for aphakia in both eyes. 92310 is the general bilateral fitting code for situations other than aphakia.

How does the technician fitting code differ?

92316 describes a technician-performed bilateral aphakia fitting. 92312 is the corresponding fitting service performed by a physician or other qualified eye-care professional.

What should the record show?

Document aphakia in both eyes, the fitting and lens-selection work, and the assessment of lens fit, vision, or adaptation. The record should make clear that the fitting addressed both eyes.

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.
