Coverage Policies

Use the index below to search for coverage information on specific medical conditions.

Note: For Arkansas State or Public School employees, services subject to pre-authorization are managed by Active Health Management, as noted in their Summary Plan Description.

For coverage information on high tech imaging (MRI, CT, PET) and nuclear medicine, administered by Evicore, click here.

Medical Providers: Payment for care or services is based on eligibility, medical necessity and available benefits at time of service and is subject to all contractual exclusions and limitations, including pre-existing conditions if applicable.

Future eligibility cannot be guaranteed and should be rechecked at time of service. Verify benefits by signing into My Account or calling Customer Service at 800.235.7111 or 501.228.7111.

If not specified in a QualChoice coverage policy (Benefit Interpretation), QualChoice follows care guidelines published by MCG Health.

QualChoice reserves the right to alter, amend, change or supplement medical policies as needed. QualChoice reviews and authorizes services and substances. CPT and HCPCS codes are listed as a convenience and any absent, new or changed codes do not alter the intent of the policy.

Effective Date: 12/01/2005 Title: Corneal Topography

Public Statement

Effective Date:

a)    This policy will apply to all services performed on or after the above revision date which will become the new effective date.

b)    For all services referred to in this policy that were performed before the revision date, contact customer service for the rules that would apply.

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.


Medical Statement

Computerized corneal topography is considered medically necessary for any of the following conditions:

    • Central corneal ulcer; OR
    • Post-traumatic corneal scarring; OR
    • Corneal edema; OR
    • Corneal dystrophy; OR
    • Diagnosing and monitoring disease progression in keratoconus; OR
    • Other corneal deformities; OR
    • Pterygium; OR
    • pseudo pterygium; OR
    • complications of transplanted cornea; OR
    • Pre- and post-penetrating keratoplasty and post kerato-refractive surgery for irregular astigmatism (when covered - see Policy Corneal remodeling); OR
    • Difficult fitting of contact lens (when contact lenses are covered – see BI066 Contact Lenses).

 

Codes Used In This BI:

 

92499             Eye service or procedure

92025             Corneal topography


Limits

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.

Application to Products
This policy applies to all health plans administered by QualChoice, both those insured by QualChoice and those that are self-funded by the sponsoring employer, unless there is indication in this policy otherwise or a stated exclusion in your medical plan booklet.
