Does Not Apply to Commercial Genetic Testing Program effective 6/1/2018
Age-related macular degeneration (AMD) is a complex disease involving both genetic and environmental (e.g., smoking) influences. Macular degeneration is the leading cause of severe vision loss in people older than age 60 and occurs when the central portion of the retina, the macula, deteriorates. AMD is divided into the dry form, associated with slowly progressive vision loss, and the wet form, which may be associated with rapidly progressive and severe vision loss.
Testing for mutations at certain genetic loci has been proposed to predict the risk of developing advanced AMD or to guide treatment. The clinical utility of genetic testing for AMD is currently limited. There are no preventive measures that can be undertaken outside of good health practices and no known association between specific genotypes and specific therapies.
Genetic testing for macular degeneration is considered investigational.

We develop Medical Policies to provide guidance to Members and Providers. This Medical Policy relates only to the services or supplies described in it. The existence of a Medical Policy is not an authorization, certification, explanation of benefits, or a contract for the service (or supply) that is referenced in the Medical Policy. For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed. If there is a conflict between the Medical Policy and a health plan, the express terms of the health plan will govern.
There is a lack of high-quality studies that show improvements in health outcomes in individuals identified as being at high risk based on genetic testing.
