    Sec. 20. Increased portability through limitation on preexisting condition exclusions.
    (A) Limitation of preexisting condition exclusion period; crediting for periods of previous coverage. Subject to subsection (D), a group health plan, and a health insurance issuer offering group health insurance coverage, may, with respect to a participant or beneficiary, impose a preexisting condition exclusion only if:
        (1) the exclusion relates to a condition (whether
    
physical or mental), regardless of the cause of the condition, for which medical advice, diagnosis, care, or treatment was recommended or received within the 6-month period ending on the enrollment date;
        (2) the exclusion extends for a period of not more
    
than 12 months (or 18 months in the case of a late enrollee) after the enrollment date; and
        (3) the period of any such preexisting condition
    
exclusion is reduced by the aggregate of the periods of creditable coverage (if any, as defined in subsection (C)(1)) applicable to the participant or beneficiary as of the enrollment date.
    (B) Preexisting condition exclusion. A group health plan, and health insurance issuer offering group health insurance coverage, may not impose any preexisting condition exclusion relating to pregnancy as a preexisting condition.
    Genetic information shall not be treated as a condition described in subsection (A)(1) in the absence of a diagnosis of the condition related to such information.

        (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).
        (4) Method of crediting coverage.
            (a) Standard method. Except as otherwise
        
provided under subparagraph (b), for purposes of applying subsection (A)(3), a group health plan, and a health insurance issuer offering group health insurance coverage, shall count a period of creditable coverage without regard to the specific benefits covered during the period.
            (b) Election of alternative method. A group
        
health plan, or a health insurance issuer offering group health insurance, may elect to apply subsection (A)(3) based on coverage of benefits within each of several classes or categories of benefits specified in regulations rather than as provided under subparagraph (a). Such election shall be made on a uniform basis for all participants and beneficiaries. Under such election a group health plan or issuer shall count a period of creditable coverage with respect to any class or category of benefits if any level of benefits is covered within such class or category.
            (c) Plan notice. In the case of an election with
        
respect to a group health plan under subparagraph (b) (whether or not health insurance coverage is provided in connection with such plan), the plan shall:
                (i) prominently state in any disclosure
            
statements concerning the plan, and state to each enrollee at the time of enrollment under the plan, that the plan has made such election; and
                (ii) include in such statements a description
            
of the effect of this election.
            (d) Issuer notice. In the case of an election
        
under subparagraph (b) with respect to health insurance coverage offered by an issuer in the small or large group market, the issuer:
                (i) shall prominently state in any disclosure
            
statements concerning the coverage, and to each employer at the time of the offer or sale of the coverage, that the issuer has made such election; and
                (ii) shall include in such statements a
            
description of the effect of such election.
        (5) Establishment of period. Periods of creditable
    
coverage with respect to an individual shall be established through presentation or certifications described in subsection (E) or in such other manner as may be specified in regulations.
    (D) Exceptions:
        (1) Exclusion not applicable to certain newborns.
    
Subject to paragraph (3), a group health plan, and a health insurance issuer offering group health insurance coverage, may not impose any preexisting condition exclusion in the case of an individual who, as of the last day of the 30-day period beginning with the date of birth, is covered under creditable coverage.
        (2) Exclusion not applicable to certain adopted
    
children. Subject to paragraph (3), a group health plan, and a health insurance issuer offering group health insurance coverage, may not impose any preexisting condition exclusion in the case of a child who is adopted or placed for adoption before attaining 18 years of age and who, as of the last day of the 30-day period beginning on the date of the adoption or placement for adoption, is covered under creditable coverage.
        The previous sentence shall not apply to coverage
    
before the date of such adoption or placement for adoption.
        (3) Loss if break in coverage. Paragraphs (1) and
    
(2) shall no longer apply to an individual after the end of the first 63-day period during all of which the individual was not covered under any creditable coverage.
    (E) Certifications and disclosure of coverage.
        (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) Disclosure of information on previous benefits.
    
In the case of an election described in subsection (C)(4)(b) by a group health plan or health insurance issuer, if the plan or issuer enrolls an individual for coverage under the plan and the individual provides a certification of coverage of the individual under paragraph (1):
            (a) upon request of such plan or issuer, the
        
entity which issued the certification provided by the individual shall promptly disclose to such requesting plan or issuer information on coverage of classes and categories of health benefits available under such entity's plan or coverage; and
            (b) such entity may charge the requesting plan or
        
issuer for the reasonable cost of disclosing such information.
        (3) Rules. The Department shall establish rules to
    
prevent an entity's failure to provide information under paragraph (1) or (2) 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 allowed under subsection (A) 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.
