(i) Facts. A group health plan provides benefits solely through an insurance policy offered by Issuer S. At the expiration of the policy, the plan switches coverage to a policy offered by Issuer T. Issuer T's policy excludes benefits for any prosthesis if the body part was lost before the effective date of coverage under the policy.
(ii) Conclusion. In this Example 1, the exclusion of benefits for any prosthesis if the body part was lost before the effective date of coverage is a preexisting condition exclusion because it operates to exclude benefits for a condition based on the fact that the condition was present before the effective date of coverage under the policy. The exclusion of benefits, therefore, is prohibited.
(i) Facts. A group health plan provides coverage for cosmetic surgery in cases of accidental injury, but only if the injury occurred while the individual was covered under the plan.
(ii) Conclusion. In this Example 2, the plan provision excluding cosmetic surgery benefits for individuals injured before enrolling in the plan is a preexisting condition exclusion because it operates to exclude benefits relating to a condition based on the fact that the condition was present before the effective date of coverage. The plan provision, therefore, is prohibited.
(i) Facts. A group health plan provides coverage for the treatment of diabetes, generally not subject to any requirement to obtain an approval for a treatment plan. However, if an individual was diagnosed with diabetes before the effective date of coverage under the plan, diabetes coverage is subject to a requirement to obtain approval of a treatment plan in advance.
(ii) Conclusion. In this Example 3, the requirement to obtain advance approval of a treatment plan is a preexisting condition exclusion because it limits benefits for a condition based on the fact that the condition was present before the effective date of coverage. The plan provision, therefore, is prohibited.
(i) Facts. A group health plan provides coverage for three infertility treatments. The plan counts against the three-treatment limit benefits provided under prior health coverage.
(ii) Conclusion. In this Example 4, counting benefits for a specific condition provided under prior health coverage against a treatment limit for that condition is a preexisting condition exclusion because it operates to limit benefits for a condition based on the fact that the condition was present before the effective date of coverage. The plan provision, therefore, is prohibited.
(i) Facts. When an individual's coverage begins under a group health plan, the individual generally becomes eligible for all benefits. However, benefits for pregnancy are not available until the individual has been covered under the plan for 12 months.
(ii) Conclusion. In this Example 5, the requirement to be covered under the plan for 12 months to be eligible for pregnancy benefits is a subterfuge for a preexisting condition exclusion because it is designed to exclude benefits for a condition (pregnancy) that arose before the effective date of coverage. The plan provision, therefore, is prohibited.
(i) Facts. A group health plan provides coverage for medically necessary items and services, generally including treatment of heart conditions. However, the plan does not cover those same items and services when used for treatment of congenital heart conditions.
(ii) Conclusion. In this Example 6, the exclusion of coverage for treatment of congenital heart conditions is a preexisting condition exclusion because it operates to exclude benefits relating to a condition based on the fact that the condition was present before the effective date of coverage. The plan provision, therefore, is prohibited.
(i) Facts. A group health plan generally provides coverage for medically necessary items and services. However, the plan excludes coverage for the treatment of cleft palate.
(ii) Conclusion. In this Example 7, the exclusion of coverage for treatment of cleft palate is not a preexisting condition exclusion because the exclusion applies regardless of when the condition arose relative to the effective date of coverage. The plan provision, therefore, is not prohibited. (But see 45 CFR 147.150, which may require coverage of cleft palate as an essential health benefit for health insurance coverage in the individual or small group market, depending on the essential health benefits benchmark plan as defined in 45 CFR 156.20).
(i) Facts. A group health plan provides coverage for treatment of cleft palate, but only if the individual being treated has been continuously covered under the plan from the date of birth.
(ii) Conclusion. In this Example 8, the exclusion of coverage for treatment of cleft palate for individuals who have not been covered under the plan from the date of birth operates to exclude benefits in relation to a condition based on the fact that the condition was present before the effective date of coverage. The plan provision, therefore, is prohibited.
