Hi,
You cont claim Medical Reimbursement from ESIC only u can avail Medical benefits ( Medical Treatment, Medicines,etc) what ever the cost maybe Free of cost, if your salary is lessthan 7500 pm & you have contributed to ESI for 6 months ie 1 contribution period april- september.
only thing you can claim from ESI is for LeavePayment ie, you can claim for the salary for the number of days on Medical leave which has to be certified by ESI medical officer.
