What 76511 covers
This diagnostic study uses reflected ultrasound signals to produce quantitative measurements of the eye. An ophthalmologist interprets the findings; trained ophthalmic staff may acquire the scan in an eye-care office or outpatient facility. It is appropriate when quantitative A-scan information is needed without a B-scan. It is distinct from A-scan biometry performed to support intraocular lens selection.
Report 76511 for the quantitative A-scan study alone, and retain documentation of the eye examined, diagnostic reason, measurements, and physician interpretation. The code has professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies equipment and staff, and no modifier represents the global service. When multiple ophthalmic diagnostic procedures are billed, the CMS multiple-procedure reduction applies to the technical component. For bilateral services, each side is paid separately at 100%.
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.

76511 billing questions
When should 76511 be reported instead of 76510?
Use 76511 for quantitative A-scan alone. Report 76510 when both B-scan and quantitative A-scan are performed during the same encounter.
Can the professional and technical services be billed separately?
Yes. Modifier 26 identifies the interpretation, and modifier TC identifies the equipment and staff portion. Billing without either modifier represents the global service.
How is bilateral 76511 handled?
CMS pays each side separately at 100% when the study is performed bilaterally. Document which eye or eyes were examined.
How does 76511 differ from A-scan biometry?
76511 is a diagnostic quantitative A-scan without B-scan imaging. Use 76516 for A-scan biometry without intraocular lens power calculation, or 76519 when that calculation is included.
What documentation supports reporting 76511?
Record the diagnostic indication, eye examined, quantitative findings, and physician interpretation. Documentation should show that the service was a quantitative A-scan only.
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.
