A Remark Code Is Not the Denial
The adjustment code says the claim was reduced. This one says why. You need both to know what to send back.
What to Do
Read the clause it claims to rely on. If the contract does not contain the restriction being applied, that is the appeal: ask them to cite the provision. A reduction that cannot be traced to the agreement it invokes is worth challenging.
