Computerized corneal topography (also known as computer assisted corneal topography, computer assisted keratography, corneal mapping or video-keratography) is a computer assisted diagnostic technique in which a special instrument projects a series of light rings on the cornea, creating a color-coded map of the corneal surface as well as a cross-section profile. This test is used for the detection of subtle corneal surface irregularities and astigmatism.
Corneal mapping is covered for an identified set of indications, but not in relation to either preoperative or postoperative care relating to non-covered refractive surgery.
Computerized corneal topography is considered medically necessary for any of the following conditions:

QualChoice does not cover corneal topography if it is performed pre- or post-operatively in relation to a non-covered procedure (i.e., refractive eye surgery). Most QualChoice benefit plans exclude coverage of refractive surgery. Please check benefit plan descriptions for details.
QualChoice considers corneal topography experimental and investigational if it is performed as part of pre-operative assessment of members with cataracts.
QualChoice considers corneal topography experimental and investigational for the management of members with interstitial keratitis, nodular degeneration of the cornea (e.g., Salzmann`s corneal degeneration), and all other indications because corneal topography has not been shown to alter the clinical management of these conditions such that clinical outcomes are improved.
