Beneficiary Health Coverage Notification Rights Act of 1999

Beneficiary Health Coverage Notification Rights Act of 1999 - Amends the Public Health Service Act and the Employee Retirement Income Security Act of 1974 to require a health insurance issuer to notify all participants and beneficiaries of an intention to terminate coverage or allow a policy to lapse because a group health plan failed to pay premiums necessary to maintain coverage. Amends such Acts and the Internal Revenue Code to deem any participant or beneficiary notified of a group health plan termination or lapse only after the fact to have been covered during the deeming period between the effective date of the termination or lapse and the date of notification. Limits the application of the deeming period to certain purposes, including reduction of pre-existing condition exclusion periods and avoidance of a significant break in coverage. Declares that nothing in this Act shall be construed as entitling any individual to any plan or coverage benefits during such deeming period.
