Official CARC description: “Payment adjusted because the payer deems the information submitted does not support this many/frequency of services.” Here’s what it actually means, why it fires, and how to get the claim paid.
Too many units or visits for the payer's policy — MUE limits, frequency caps (one screening per year), or utilization edits. Recoverable when the quantity was clinically real and documented.
Liability group: CO = Contractual Obligation — the provider absorbs it — the amount cannot be billed to the patient. If the denial is wrong, the money is recovered by correcting or appealing the claim, not by balance-billing.
Check the MUE value and its adjudication indicator for the CPT
If billing style was wrong (units vs modifiers): corrected claim
If quantity is real: appeal with records showing each unit's necessity
Track frequency-capped services at scheduling so patients aren't booked into denials
Appeal with documentation itemising every unit (times, sites, medical need). For MUE denials with adjudication indicator 3, per-line documentation review is explicitly available — use it.
Fill in the denial facts — use placeholders, never real patient data (the letter keeps [PATIENT NAME]-style fields so you can merge real details privately). A payer-ready draft with an enclosure checklist comes back in ~20 seconds.
