What 76513 covers
This diagnostic study uses ultrasound to image the front portion of the eye, including structures that may be difficult to assess through the cornea or with routine examination. It is commonly performed in ophthalmology practices by trained imaging staff, with the ophthalmologist interpreting the images and documenting the findings. Ultrasound biomicroscopy is a familiar application when detailed anterior-segment imaging is needed, such as evaluating the angle or ciliary body.
Report the service when the study and interpretation address the anterior segment, rather than posterior-segment imaging, corneal thickness, or ocular biometry. Documentation should identify the clinical reason, eye examined, imaging findings, and interpretation. The code may be billed globally or as a professional component with modifier 26 or a technical component with modifier TC. For bilateral studies, CMS pays each side separately at 100%. When multiple ophthalmology diagnostic procedures are performed, the multiple-procedure reduction applies to the technical component.

How to choose
- 76512Eye ultrasoundDiagnostic B-scan
- Choose 76513 for anterior-segment imaging; choose 76512 for B-scan evaluation of the posterior segment.
- 76510Eye ultrasoundB-scan and quantitative A-scan
- 76510 combines B-scan and quantitative A-scan components. It is not the anterior-segment study reported with 76513.
- 76514Corneal pachymetryUltrasonic thickness measurement
- 76514 measures eye thickness, while 76513 images anterior-segment structures such as the angle or ciliary body.
- 76516Eye biometryUltrasound A-scan
- 76516 is used for ocular biometry; 76513 evaluates the anterior segment rather than measuring the eye for biometry.
76513 billing questions
When should this code be chosen instead of 76512?
Use 76513 for diagnostic ultrasound imaging of the anterior segment. Code 76512 describes B-scan imaging used to evaluate the eye’s posterior segment.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the interpretation, and modifier TC identifies the equipment and staff portion. Without either modifier, the claim represents the global service.
How is a bilateral study handled?
Document which eye or eyes were examined. CMS pays each side separately at 100% when the study is performed bilaterally.
Does the multiple-procedure reduction affect both components?
The ophthalmology diagnostic multiple-procedure reduction applies to the technical component of this service.
What documentation supports reporting 76513?
Record the clinical indication, laterality, anterior-segment images or findings, and the interpreting physician’s report. The record should support that the study evaluated the anterior segment.
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.
