If a person has chronic diseases like Cancer, heart problem, brain tumor he can take treatment in any big hospitals and ESI will reimburse it. This benefit is very useful for a normal poor worker. Many workers got benefits from this by taking treatment in big hospitals. A normal poor worker can never imagine of taking treatment in corporate hospital. Everything is package sytem now. They need to spend 2 to 3 lakhs. Recently one retired transport worker had a clot in the brain. He had sever headache. and we took him to corporate hospital. Without opening skull with some latest drilling technique they did a surgery and the operation went for 1 hour. They charged Rs. 6lakh for the operation. He is retired now, so he cannot get ESI benefit. They took loans and managed it. If at all he was in service he should have got ESI benefit.
