Yes. There is a difference between euthanasia and medically assisted death. Euthanasia assumes that a doctor/physician is actively involved in providing dying assistance, e.g. via a lethal injection. Physician-assisted death or physician-assisted suicide means that a doctor provides the means for the suicide but does not execute it personally.
This difference, though, is not relevant for life insurance providers. As long as the health and legal conditions for the medically assisted death are fulfilled, life insurers treat euthanasia and medically assisted death in the same way.
