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
Get the payer's criteria for that category and compare the record against each one. If the item or service meets them, appeal with the records that show each criterion is met. If it fits a different category, correct the code and resubmit instead.
