Is rehabilitation medicine included in the scope of medical insurance?

Rehabilitation medicine is included in the scope of medical insurance, but there are restrictions on the duration of treatment. If the cause of the disease is clear, for example, in Zhejiang, treatment can last for 3 months, but this is not always the case. If treatment is indeed necessary, the course of treatment can be extended appropriately, but it requires identification and application by a rehabilitation physician with qualifications recognized by medical insurance, which is a rather cumbersome process.
