Because root canal treatment is an outpatient procedure, it is not reimbursable by health insurance, but the money in your health insurance account can be used for root canal treatment. If a tooth requires a root canal during a hospital stay, reimbursement will be determined on a case-by-case basis. If you do not overspend on your health insurance during your hospitalization, and if you are approved by the health insurance office, you will be reimbursed for root canal treatment. If the individual’s medical insurance is overcharged and the medical insurance office does not approve the treatment, the root canal will not be reimbursed and the root canal will have to be paid for out of pocket. Therefore, whether or not root canal treatment is covered by health insurance is determined on a case-by-case basis.
