(b) Definitions For purposes of this section—
(1) Preexisting condition exclusion
(A) In general

The term “preexisting condition exclusion” means, with respect to coverage, a limitation or exclusion of benefits relating to a condition based on the fact that the condition was present before the date of enrollment for such coverage, whether or not any medical advice, diagnosis, care, or treatment was recommended or received before such date.

(B) Waiting period not treated as a break in coverage

For purposes of subparagraph (A) and subsection (d)(4), any period that an individual is in a waiting period for any coverage under a group health plan or is in an affiliation period shall not be taken into account in determining the continuous period under subparagraph (A).

(ii) such entity may charge the requesting plan or issuer for the reasonable cost of disclosing such information.
(3) Regulations

The Secretary 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.
