Yes, travel insurance is a sensible addition to a trip built around Oujda, a city in eastern Morocco close to the Algerian border that sees far fewer foreign visitors than Marrakech or Fes. The honest case for coverage here has more to do with distance from the country's major hospital centers than with any unusual danger, and a policy still absorbs the ordinary costs of a delayed flight or a misplaced bag in an unfamiliar country.
Oujda has regional hospital care for routine matters, but anything complex or specialist is typically referred toward Rabat or Casablanca, the country's principal medical centers, a domestic flight or a long day's drive to the west. Confirm your policy covers treatment and transfer between Moroccan cities, since the referral leg is the part most likely to involve real distance and cost.
Many visitors use Oujda as a base for day trips to Saidia, the Mediterranean beach town roughly an hour north, or as a stop before continuing deeper into the Oriental region toward the Algerian frontier. Border-area travel of this kind is routine rather than risky, but check that your policy does not quietly narrow cover near international frontiers, since some standard policies carve out exclusions close to borders.
Summers around Oujda run hot and dry, and the wider Oriental region occasionally sees short, intense autumn downpours that can flood low-lying roads with little warning even in an otherwise arid climate. Trip-delay cover is worth checking if your visit falls in this window, though it is not the defining risk here the way it might be elsewhere.
Keep any clinic paperwork from Oujda and receipts for onward travel if you are referred to Rabat or Casablanca for treatment, since claims spanning two cities need documentation for each leg. Check whether your existing health cover extends abroad and specifically to Morocco before you rely on it, and confirm your policy's claims-reporting window rather than assuming automatic reimbursement.
