What is the difference between CPT 92133 and 92134?

92133: scanning computerized ophthalmic diagnostic imaging, posterior segment, with interpretation and report, unilateral or bilateral; optic nerve. 92134: scanning computerized ophthalmic diagnostic imaging, posterior segment, with interpretation and report, unilateral or bilateral; retina.

How often can you bill CPT 92134?

4 times per year
92134 is allowed more often – typically up to 4 times per year – or once per month in patients with retinal conditions undergoing active intravitreal drug treatment. 2 Clear documen-tation of the reason for testing is always required. Too-frequent testing can garner unwanted attention.

What is an OCT code?

On Jan. 1, a new Level I code replaced a Category III code for anterior segment OCT, which is also known as scanning computerized ophthalmic diagnostic imaging (SCODI). New code—92132 Scanning computerized ophthalmic diagnostic imaging, anterior segment, with interpretation and report, unilateral or bilateral.

Is optical coherence tomography covered by Medicare?

Medicare item 11219: Optical coherence tomography (OCT) OCT scans for ongoing monitoring of disease are not currently reimbursed by Medicare.

What does tomography, optical coherence mean?

Optical coherence tomography ( OCT) is an imaging technique that uses low-coherence light to capture micrometer -resolution, two- and three-dimensional images from within optical scattering media (e.g., biological tissue). It is used for medical imaging and industrial nondestructive testing (NDT). Optical coherence tomography is based on low-coherence interferometry, typically employing near-infrared light.

What is optical coherence tomography for the retina?

Optical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take cross-section pictures of your retina. With OCT, your ophthalmologist can see each of the retina’s distinctive layers. This allows your ophthalmologist to map and measure their thickness.

Who invented optical coherence tomography?

Optical coherence tomography was first introduced commerically by Carl Zeiss in 1996. The first commerically available OCT was based on time-domain technology (TD).

What is the most common CPT codes?

The most frequently used codes are medical Evaluation and Management (E/M) codes, which are part of the CPT code system. They are included in the range of numbers from 90000 to 99999.
