What 76514 covers
This service uses an ultrasound probe to measure corneal thickness, commonly the central cornea. Ophthalmologists and optometrists may order it during evaluation of glaucoma risk or corneal conditions, or when thickness information is needed for another eye-care decision. It is performed in settings such as an ophthalmology office or outpatient eye clinic.
Report the code for the ultrasonic thickness study whether one eye or both eyes are examined; CMS prices it as bilateral, so modifier 50 does not increase payment. Documentation should identify the clinical reason, eye or eyes assessed, measurements, and interpretation. The service has professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff portion, and an unmodified claim represents the global service. When multiple ophthalmology diagnostic procedures are performed, the multiple-procedure reduction applies to the technical component.
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.

76514 billing questions
Should this code be reported for one eye or both eyes?
It covers ultrasonic corneal thickness measurement for one or both eyes. CMS prices it as bilateral, so modifier 50 does not increase payment.
How does this differ from 76513?
76514 measures corneal thickness. Code 76513 is ultrasound biomicroscopy of the anterior segment, a different diagnostic examination.
Can the professional and technical portions be billed separately?
Yes. Use modifier 26 for the interpretation and modifier TC for the equipment and staff portion. Billing without either modifier represents the global service.
Does the multiple-procedure reduction affect both components?
The ophthalmology diagnostic multiple-procedure reduction applies to the technical component.
What documentation supports reporting this service?
Document the clinical indication, the eye or eyes examined, the thickness measurements, and the interpretation.
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.
