Usually no under travel-style student cover. These policies are generally not intended to work like broad private medical insurance for routine care, optional treatment, or elective procedures.
The focus is usually on accidents, sudden illness, urgent care, and specific insured events. If treatment is planned in advance, cosmetic, elective, or non-emergency, the safest assumption is that it will not be covered unless the policy documents say otherwise.
This is one of the most important expectation-setting points in the whole Help Centre.
