Readers ask: Is Corneal Topography Necessary?

Computer-assisted corneal topography is considered not medically necessary to detect or monitor disea ses of the cornea. Computerized Corneal Topography is considered not medically necessary if performed pre- or post-operatively in relation to a non-covered procedure (i.e., refractive surgery).

When is corneal topography necessary?

It is a noninvasive medical imaging technique used for mapping the surface curvature of the cornea. Since the cornea is normally responsible for approximately 70% of the eye’s refractive power, its topography is of critical importance in determining the quality of vision.

Is corneal topography necessary for cataract surgery?

Corneal topography can help you accurately place relaxing incisions and predict problems with a patient’s vision postop, say surgeons. Corneal topography is indispensable in refractive surgery, but it’s very useful before cataract surgery, as well.

Is corneal topography covered by insurance?

Corneal topography is a covered service for the above indications when medically reasonable and necessary only if the results will assist in defining further treatment. It is not covered for routine follow-up testing.

How much does a corneal topography cost?

On MDsave, the cost of a Computerized Corneal Topography ranges from $37 to $65. Those on high deductible health plans or without insurance can save when they buy their procedure upfront through MDsave.

What does corneal topography diagnose?

A corneal topography test provides detailed 3D maps of the cornea’s shape and curvature and enables detection of corneal diseases, and irregular corneal conditions, such as swelling, scarring, abrasions, deformities, and irregular astigmatisms.

What is topography of the eye?

Corneal topography is a special photography technique that maps the surface of the clear, front window of the eye (the cornea). It works much like a 3D (three-dimensional) map of the world, that helps identify features like mountains and valleys.

How long does a corneal topography take?

He was so gentle; the procedure took less than 20 minutes and pain free. I would recommend everyone to have this procedure done and be set free from glasses forever!

What is the difference between topography and tomography?

Results: Topography is the study of the shape of the corneal surface, while tomography allows a three-dimensional section of the cornea to be presented. Corneal topographers can be divided into large- and small-cone Placido-based devices, as well as devices with color-LEDs.

What is the astigmatism?

Overview. Astigmatism (uh-STIG-muh-tiz-um) is a common and generally treatable imperfection in the curvature of the eye that causes blurred distance and near vision. Astigmatism occurs when either the front surface of the eye (cornea) or the lens inside the eye has mismatched curves.

What is considered irregular astigmatism?

Irregular Astigmatism In irregular astigmatisms, the principal meridians are separated by any angle other than 90°, i.e., they are not perpendicular to each other. In this type, the curvature at each meridian is not uniform but changes from one point to another across the entrance of the pupil.

How often can you bill 92136?

The technical portion of either 76519 or 92136 and the respective interpretations for the same patient should not be billed more than once during a 12 month period by the same provider/physician/group unless there is a significant change in vision.

Does Medicare cover corneal topography for cataract surgery?

Q: What is Medicare’s position on corneal topography and refractive surgery? A: Refractive surgery for the purpose of reducing dependence on eyeglasses or contact lenses is not covered by Medicare, nor are the associated diagnostic tests, including corneal topography (NCD §80.7).

Can you see without a cornea?

The cornea helps the eye focus as light makes its way through. It is a very important part of the eye, but you can hardly see it because it’s made of clear tissue.

Can eye cornea be replaced?

A cornea transplant ( keratoplasty ) is a surgical procedure to replace part of your cornea with corneal tissue from a donor. Your cornea is the transparent, dome-shaped surface of your eye.

Are cornea transplants successful?

Cornea transplants are performed routinely and have a reasonable success rate. In fact, cornea grafts are the most successful of all tissue transplants. Cornea transplant rejection can be reversed in 9 out of 10 cases if detected early enough.
