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
Find what was requested. The codes printed beside this one usually name it. Add it and submit a new claim. Do not appeal: the payer has asked for a resubmission, so an appeal only adds a wait while the filing clock keeps running.
