Industrial accident treatment requirements: ① must use industrial-designated facilities (산재지정병원) for coverage, ② Korean medicine clinics can be designated, ③ exception: emergency cases at any facility, then transfer, ④ if treatment at non-designated facility, may need to pay out-of-pocket. Verify clinic designation before treatment. Most major Korean medicine clinics are designated. Industrial accident worker can choose any designated facility — not limited to one near workplace.
