PREEXISTING CONDITION PROVISION.

(a) In this section, "creditable coverage" has the meaning assigned by Section 1205.004.

(b) A preexisting condition provision in a multiple employer welfare arrangement's plan document may apply only to coverage for a disease or condition for which medical advice, diagnosis, care, or treatment was recommended or received during the six months before the earlier of:

(1) the effective date of coverage; or

(2) the first day of the waiting period.

(c) A preexisting condition provision in a multiple employer welfare arrangement's plan document may not apply to expenses incurred on or after the expiration of the 12 months following the initial effective date of coverage of the participating employee, dependent, or late-participating employee or dependent.

(d) A preexisting condition provision in a multiple employer welfare arrangement's plan document may not apply to an individual who was continuously covered for an aggregate period of 12 months under creditable coverage that was in effect until a date not more than 63 days before the effective date of coverage under the health benefit plan, excluding any waiting period.

(e) In determining whether a preexisting condition provision applies to an individual covered by a multiple employer welfare arrangement's plan document, the arrangement shall credit the time the individual was covered under previous creditable coverage if the previous coverage was in effect at any time during the 12 months preceding the effective date of coverage under the arrangement. If the previous coverage was issued under a health benefit plan, any waiting period that applied before that coverage became effective must also be credited against the preexisting condition provision period.
