(d) to correct an error or omission in the registration.
(2) A decision under this section takes effect:
(a) when it is made; or
(b) if the decision is made at the request of the healthcare recipient or other entity, and the request states that the healthcare recipient or other entity wishes the variation to occur at a specified future time--at that future time.
