Prohibition of preexisting condition exclusions.

Official textecfr.govlast amended Jul 27, 2026

# (a) No preexisting condition exclusions.

A group health plan, or a health insurance issuer offering group health insurance coverage, may not impose any preexisting condition exclusion (as defined in § 54.9801-2).

# (b) Examples.

The rules of paragraph (a) of this section are illustrated by the following examples (for additional examples illustrating the definition of a preexisting condition exclusion, see § 54.9801-3(a)(2)):

Example 1.

(i) Facts. A group health plan provides benefits solely through an insurance policy offered by Issuer P. At the expiration of the policy, the plan switches coverage to a policy offered by Issuer N. N's policy excludes benefits for oral surgery required as a result of a traumatic injury if the injury occurred before the effective date of coverage under the policy.

(ii) Conclusion. In this Example 1, the exclusion of benefits for oral surgery required as a result of a traumatic injury if the injury occurred 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. Therefore, such an exclusion is prohibited.

Example 2.

(i) Facts. Individual C applies for individual health insurance coverage with Issuer M. M denies C's application for coverage because a pre-enrollment physical revealed that C has type 2 diabetes.

(ii) Conclusion. See Example 2 in 45 CFR 147.108(a)(2) for a conclusion that M's denial of C's application for coverage is a preexisting condition exclusion because a denial of an application for coverage based on the fact that a condition was present before the date of denial is an exclusion of benefits based on a preexisting condition. Therefore, such an exclusion is prohibited.

# (c) Applicability date.

The provisions of this section are applicable to group health plans and health insurance issuers for plan years beginning on or after January 1, 2017. Until the applicability date for this regulation, plans and issuers are required to continue to comply with the interim final regulations promulgated by the Department of Labor at 29 CFR part 2590, contained in the 29 CFR, parts 1927 to end, edition revised as of July 1, 2015.
