How can I file a grievance?

You can call, write or visit First Medical Service Centers to file a grievance. Your physician, a relative or a person authorized by you, can file the grievance on your behalf.

You may file a grievance at any time from the date of the occurrence. The insurer shall acknowledge receipt of your grievance in writing to you (and the provider, if the provider filed the grievance on your behalf) within ten (10) business days of receipt.
