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
Decide first whether the two really were separate work. If they were, the modifier plus a note that documents the separate service is what wins it. If they were not, this is a correct denial and appealing it costs time you could spend on a winnable one.
