A hospital stay rarely starts at admission. There is usually a specialist consultation and tests beforehand, and follow-up visits and medicines after discharge. Most hospital plans pay for these as pre- and post-hospitalisation benefits.
Plans set how many days before admission and after discharge are covered, and a limit on the amount. Both vary by plan and insurer.
The treatment must relate to the condition the employee was admitted for. A routine check-up in the same week would not count.
