        (3) Not counting periods before significant breaks in coverage.
            (a) In general. A period of creditable coverage shall not be counted, with respect
        
to enrollment of an individual under a group health plan, if, after such period and before the enrollment date, there was a 63-day period during all of which the individual was not covered under any creditable coverage.
            (b) Waiting period not treated as a break in coverage. For purposes of subparagraph
        
(a) and subsection (D)(3), any period that an individual is in a waiting period for any coverage under a group health plan (or for group health insurance coverage) or is in an affiliation period (as defined in subsection (G)(2)) shall not be taken into account in determining the continuous period under subparagraph (a).

        (1) Requirement for Certification of Period of Creditable Coverage.
            (a) A group health plan, and a health insurance issuer offering group health
        
insurance coverage, shall provide the certification described in subparagraph (b):
                (i) at the time an individual ceases to be covered under the plan or otherwise
            
becomes covered under a COBRA continuation provision;
                (ii) in the case of an individual becoming covered under such a provision, at
            
the time the individual ceases to be covered under such provision; and
                (iii) on the request on behalf of an individual made not later than 24 months
            
after the date of cessation of the coverage described in clause (i) or (ii), whichever is later.
        The certification under clause (i) may be provided, to the extent practicable, at a time
        
consistent with notices required under any applicable COBRA continuation provision.
            (b) The certification described in this subparagraph is a written certification of:
                (i) the period of creditable coverage of the individual under such plan and the
            
coverage (if any) under such COBRA continuation provision; and
                (ii) the waiting period (if any) (and affiliation period, if applicable) imposed
            
with respect to the individual for any coverage under such plan.
            (c) To the extent that medical care under a group health plan consists of group
        
health insurance coverage, the plan is deemed to have satisfied the certification requirement under this paragraph if the health insurance issuer offering the coverage provides for such certification in accordance with this paragraph.
        (2) (Blank).
        (3) Rules. The Department shall establish rules to prevent an entity's failure to
    
provide information under paragraph (1) with respect to previous coverage of an individual from adversely affecting any subsequent coverage of the individual under another group health plan or health insurance coverage.
        (4) Treatment of certain plans as group health plan for notice provision. A program
    
under which creditable coverage described in subparagraph (c), (d), (e), or (f) of Section 20(C)(1) is provided shall be treated as a group health plan for purposes of this Section.
    (F) Special enrollment periods.
        (1) Individuals losing other coverage. A group health plan, and a health insurance
    
issuer offering group health insurance coverage in connection with a group health plan, shall permit an employee who is eligible, but not enrolled, for coverage under the terms of the plan (or a dependent of such an employee if the dependent is eligible, but not enrolled, for coverage under such terms) to enroll for coverage under the terms of the plan if each of the following conditions is met:
            (a) The employee or dependent was covered under a group health plan or had health
        
insurance coverage at the time coverage was previously offered to the employee or dependent.
            (b) The employee stated in writing at such time that coverage under a group health
        
plan or health insurance coverage was the reason for declining enrollment, but only if the plan sponsor or issuer (if applicable) required such a statement at such time and provided the employee with notice of such requirement (and the consequences of such requirement) at such time.
            (c) The employee's or dependent's coverage described in subparagraph (a):
                (i) was under a COBRA continuation provision and the coverage under such
            
provision was exhausted; or
                (ii) was not under such a provision and either the coverage was terminated as a
            
result of loss of eligibility for the coverage (including as a result of legal separation, divorce, death, termination of employment, or reduction in the number of hours of employment) or employer contributions towards such coverage were terminated.
            (d) Under the terms of the plan, the employee requests such enrollment not later
        
than 30 days after the date of exhaustion of coverage described in subparagraph (c)(i) or termination of coverage or employer contributions described in subparagraph (c)(ii).
        (2) For dependent beneficiaries.
            (a) In general. If:
                (i) a group health plan makes coverage available with respect to a dependent of
            
an individual,
                (ii) the individual is a participant under the plan (or has met any waiting
            
period applicable to becoming a participant under the plan and is eligible to be enrolled under the plan but for a failure to enroll during a previous enrollment period), and
                (iii) a person becomes such a dependent of the individual through marriage,
            
birth, or adoption or placement for adoption,
        then the group health plan shall provide for a dependent special enrollment period
        
described in subparagraph (b) during which the person (or, if not otherwise enrolled, the individual) may be enrolled under the plan as a dependent of the individual, and in the case of the birth or adoption of a child, the spouse of the individual may be enrolled as a dependent of the individual if such spouse is otherwise eligible for coverage.
            (b) Dependent special enrollment period. A dependent special enrollment period
        
under this subparagraph shall be a period of not less than 30 days and shall begin on the later of:
                (i) the date dependent coverage is made available; or
                (ii) the date of the marriage, birth, or adoption or placement for adoption (as
            
the case may be) described in subparagraph (a)(iii).
            (c) No waiting period. If an individual seeks to enroll a dependent during the
        
first 30 days of such a dependent special enrollment period, the coverage of the dependent shall become effective:
                (i) in the case of marriage, not later than the first day of the first month
            
beginning after the date the completed request for enrollment is received;
                (ii) in the case of a dependent's birth, as of the date of such birth; or
                (iii) in the case of a dependent's adoption or placement for adoption, the date
            
of such adoption or placement for adoption.
    (G) Use of affiliation period by HMOs as alternative to preexisting condition exclusion.
        (1) In general. A health maintenance organization which offers health insurance
    
coverage in connection with a group health plan and which does not impose any pre-existing condition exclusion with respect to any particular coverage option may impose an affiliation period for such coverage option, but only if:
            (a) such period is applied uniformly without regard to any health status-related
        
factors; and
            (b) such period does not exceed 2 months (or 3 months in the case of a late
        
enrollee).
        (2) Affiliation period.
            (a) Defined. For purposes of this Act, the term "affiliation period" means a period
        
which, under the terms of the health insurance coverage offered by the health maintenance organization, must expire before the health insurance coverage becomes effective. The organization is not required to provide health care services or benefits during such period and no premium shall be charged to the participant or beneficiary for any coverage during the period.
            (b) Beginning. Such period shall begin on the enrollment date.
            (c) Runs concurrently with waiting periods. An affiliation period under a plan
        
shall run concurrently with any waiting period under the plan.
        (3) Alternative methods. A health maintenance organization described in paragraph (1)
    
may use alternative methods, from those described in such paragraph, to address adverse selection as approved by the Department.
