Insurers that provide Medicare supplement policies or certificates only may not deny or condition the issuance or effectiveness of insurance, including pre-existing condition exclusions, on the basis of genetic information. Insurers of these policies or certificates may not (1) discriminate with respect to pricing on the basis of genetic information, (2) request or require an individual or family member to undergo a genetic test (with an exception regarding requesting a test), or (3) use the manifestation of disease in an individual as genetic information about another group members and to further increase premiums for the group. Insurers may request a genetic test from an individual or family member only if the request is pursuant to research that applies to the Common Rule and other criteria are met.
