Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 76516 covers

This service uses ultrasound A-scan measurements to determine ocular dimensions, including axial length. Ophthalmologists use the measurements in evaluating eyes, often when assessing a patient for cataract surgery and optical measurements are unavailable or unreliable. Ophthalmic staff may obtain the technical measurements, with a physician providing the interpretation. The service is commonly furnished in an ophthalmology office or an outpatient setting.

Choose this code for ultrasound biometry without intraocular lens power calculation; use the code-specific distinction from 76519 when that calculation is performed. Documentation should identify the eye measurements obtained and support the clinical reason for the study. The code is priced as bilateral, so modifier 50 does not increase payment. Bill globally without a modifier, or separate the interpretation with modifier 26 and the equipment and staff service with modifier TC. The ophthalmology diagnostic multiple-procedure reduction applies to the technical component.
