CPT® Code 76519

Ophthalmic biometry by ultrasound echography is a diagnostic procedure that utilizes a single dimension, amplitude (A-scan) modulated sound beam emitted from the tip of an ultrasound probe. This technique is specifically designed to measure the length of the eye, which is a critical factor in determining the appropriate refractive power needed for intraocular lens (IOL) implants. The procedure is particularly significant in the context of cataract surgery, where the natural crystalline lens of the eye is removed and replaced with an artificial lens. The cornea and crystalline lens together provide the eye's refractive power, and accurate measurements are essential to ensure that the IOL is correctly calculated to restore optimal vision. The data obtained from the A-scan, in conjunction with keratometry measurements, are applied to a formula that calculates the necessary power of the IOL. It is important to note that while code 76516 is designated for ophthalmic biometry (A-scan) alone, code 76519 specifically encompasses the procedure of ophthalmic biometry (A-scan) along with the intraocular lens power calculation, highlighting its comprehensive nature in the context of cataract surgery and vision correction.
