Complications caused by conditions not covered under your plan

This exclusion on a medical insurance policy means that the policy may not cover expenses incurred because of complications directly caused by an illness, injury, or treatment for which cover is excluded or limited under the plan. A complication in medicine, or medical complication, is an unfavorable result of a disease, health condition, or treatment. Complications may adversely affect the prognosis, or outcome, of a disease. Complications generally involve a worsening in severity of disease or illness and the development of new signs, symptoms, or pathological changes which may become widespread throughout the body and affect other organ systems. Thus, complications may lead to the development of new diseases resulting from a previously existing disease and may be quite severe in nature. Complications may also arise as a result of various treatments and may lead to worsening health state of the patient. This exclusion applies to any expenses incurred due to complications that arise from an illness, injury, or treatment that is already excluded or limited under the plan.
