For functional mental disorders, such as schizophrenia, severe depression, and bipolar disorder, the length of hospitalization is 1-3 months, and the overall hospitalization cost is about 10,000-50,000, with the individual bearing about 3,000-10,000 yuan after medical insurance reimbursement. At present, the national policy is to provide subsidies to patients with mental disorders who are hospitalized, which means that they can be given secondary subsidies on top of the regular medical insurance reimbursement, especially for poor patients and rural patients. The cost of hospitalization and subsidy policy varies from region to region and from hospital to hospital, but in view of the increasing concern of the state and government about mental disorders in recent years, and the trend of support, the cost of hospitalization for mental disorders in each region will not be very high, and will also be lower and lower.
