((a))
((1)) In any case in which a person (or the person’s dependents) has coverage under a health plan in connection with the person’s position of employment, including a group health plan (as defined in section 607(1) of the Employee Retirement Income Security Act of 1974), and such person is absent from such position of employment by reason of service in the uniformed services, or such person becomes eligible for medical and dental care under chapter 55 of title 10 by reason of subsection (d) of section 1074 of that title, the plan shall provide that the person may elect to continue such coverage as provided in this subsection. The maximum period of coverage of a person and the person’s dependents under such an election shall be the lesser of—
((A)) the 24-month period beginning on the date on which the person’s absence begins; or
((B)) the day after the date on which the person fails to apply for or return to a position of employment, as determined under section 4312(e).
((2)) A person who elects to continue health-plan coverage under this paragraph may be required to pay not more than 102 percent of the full premium under the plan (determined in the same manner as the applicable premium under section 4980B(f)(4) of the Internal Revenue Code of 1986) associated with such coverage for the employer’s other employees, except that in the case of a person who performs service in the uniformed services for less than 31 days, such person may not be required to pay more than the employee share, if any, for such coverage.
((3)) In the case of a health plan that is a multiemployer plan, as defined in section 3(37) of the Employee Retirement Income Security Act of 1974, any liability under the plan for employer contributions and benefits arising under this paragraph shall be allocated—
((A)) by the plan in such manner as the plan sponsor shall provide; or
((B)) if the sponsor does not provide—
((i)) to the last employer employing the person before the period served by the person in the uniformed services, or
((ii)) if such last employer is no longer functional, to the plan.
((b))
((1)) Except as provided in paragraph (2), in the case of a person whose coverage under a health plan was terminated by reason of service in the uniformed services, or by reason of the person’s having become eligible for medical and dental care under chapter 55 of title 10 by reason of subsection (d) of section 1074 of that title, an exclusion or waiting period may not be imposed in connection with the reinstatement of such coverage upon reemployment under this chapter if an exclusion or waiting period would not have been imposed under a health plan had coverage of such person by such plan not been terminated as a result of such service or eligibility. This paragraph applies to the person who is reemployed and to any individual who is covered by such plan by reason of the reinstatement of the coverage of such person.
((2)) Paragraph (1) shall not apply to the coverage of any illness or injury determined by the Secretary of Veterans Affairs to have been incurred in, or aggravated during, performance of service in the uniformed services.
((3)) In the case of a person whose coverage under a health plan is terminated by reason of the person having become eligible for medical and dental care under chapter 55 of title 10 by reason of subsection (d) of section 1074 of that title but who subsequently does not commence a period of active duty under the order to active duty that established such eligibility because the order is canceled before such active duty commences, the provisions of paragraph (1) relating to any exclusion or waiting period in connection with the reinstatement of coverage under a health plan shall apply to such person’s continued employment, upon the termination of such eligibility for medical and dental care under chapter 55 of title 10 that is incident to the cancellation of such order, in the same manner as if the person had become reemployed upon such termination of eligibility.
