Paragraph (1) shall not be construed to require a health plan to comply with any standard, implementation specification, or modification to a standard or specification adopted or established by the Secretary under sections 1320d–1 through 1320d–3 of this title at any time prior to the date on which the plan is required to comply with the standard or specification under subsection (b).
In the case of a small health plan, paragraph (1) shall be applied by substituting “36 months” for “24 months”. For purposes of this subsection, the Secretary shall determine the plans that qualify as small health plans.
If the Secretary adopts a modification to a standard or implementation specification under this part, each person to whom the standard or implementation specification applies shall comply with the modified standard or implementation specification at such time as the Secretary determines appropriate, taking into account the time needed to comply due to the nature and extent of the modification. The time determined appropriate under the preceding sentence may not be earlier than the last day of the 180-day period beginning on the date such modification is adopted. The Secretary may extend the time for compliance for small health plans, if the Secretary determines that such extension is appropriate.
