Request for Assistance with Health Policy

Hi everyone, I have a question regarding our health policy in MNCs especially in TCS, infosys and capgemini. If someone resigns in June, are they eligible for health benefits only until their last working day, or can they continue receiving coverage until December (up to 12 months)? I’d appreciate any insights or clarifications on this matter. the people who working in these companies will get info easily via the helpline number of health card please help on this. Thank you!"
