Delaware Code Title 18. Insurance Code § 3573. Limitations on preexisting condition limitations

(1) Shall not deny, exclude or limit benefits for a covered individual because of a preexisting condition;

(2) May impose an affiliation period. An affiliation period shall run concurrently with any waiting period. A health maintenance organization may, in lieu of an affiliation period, use an alternative method to address adverse selection with the prior approval of the Commissioner;

(3) Shall waive an affiliation period for the period of time an individual was previously covered by creditable coverage if such creditable coverage was continuous to a date not more than 63 days prior to the effective date of the new coverage. For purposes of calculating continuous coverage, a waiting period shall not be considered a gap in coverage. This paragraph shall not preclude application of any waiting period applicable to all new enrollees under the plan. The method of crediting and certifying coverage shall be determined by the Commissioner by regulation; and

(4) May not exclude coverage for late enrollees for a preexisting condition.
