Your call, IMO leave it be unless you find the piece that actually broke off then add it back on.
Was a great story about a huge buck killed last year in Wisconsin where the main beam had a piece broken
off and another hunter found the piece 1 1/2 miles away and B&C might allow it for scoring because it is the original. This buck scored over 200". I believe the article was in Wisconsin Sportsman magazine and I will see if I can find my copy and give a follow up. They were talking actually 214 with the piece added.
