Box 11 - is for the insured’s policy group or feca number. Not all insurance
carriers issue group numbers. If there is no group or policy number, leave
this box blank. If there is a group number on the insurance id card put it in
this box. In most cases, the lack of a group number will not affect the
payment of your claim, but there are a few exceptions. Our Medicare office
requires that you put the word “none” in this box. If you do not have the
word “none” in this box Medicare denies the claim
