Femur Issue Claim

Between 2002-2004, a veteran hurt himself in basic training (Army).

He had a rod inserted into his right femur and was discharged from active duty.

He later in 2018, filed a claimed for benefits.

He was service connected at 0%.

 

I want to help the veteran with the supplemental claim.

However he is hard to get information from.

What rating code would the right femur injury fall under?
