PR-154: Documentation Does Not Support Day's Supply of Medication/Supplies

What Does PR-154 Mean?

PR-154 is less common and may appear when the patient is responsible for the cost of medication or supplies exceeding the covered day's supply — for example, when the patient requested a larger quantity than the plan allows and agreed to pay the difference.

CARC 154 appears on your remittance when the payer has reviewed the claim and concluded that the information provided does not justify the amount of medication or supplies billed for that day or dispensing period. This is a quantity-and-supply denial — closely related to CARC 153 (dosage) but focused specifically on the day's supply or total quantity dispensed rather than the dosage per administration.

The most common trigger is a data entry error in the day's supply field. Pharmacy and DME billing systems require precise day's supply calculations, and even a small error — billing 90 days when the prescription calls for 30, or miscalculating the supply based on the dosing frequency — can cause this denial. The second major cause is payer quantity limits: many payers restrict the maximum day's supply for initial prescriptions, controlled substances, or specialty medications to 30 days, and billing for a larger supply without prior authorization triggers CARC 154.

This denial typically appears under the CO group code, making the provider financially responsible. The fix is usually straightforward: verify the day's supply on the claim against the prescription, check the payer's quantity limits, and correct any discrepancies. If the day's supply is clinically appropriate and the prescription supports it, an appeal with the prescription documentation and clinical rationale should resolve the denial.

How to Resolve

Verify the day's supply matches the prescription and falls within payer limits, then correct any errors or appeal with prescription documentation.

1. Confirm PR assignment Verify with the payer that the excess supply cost is correctly assigned as patient responsibility.
2. Collect from the patient Notify the patient of the amount owed for the excess supply and offer payment options.

How to Prevent PR-154

• Inform patients upfront when a requested day's supply exceeds their plan's covered quantity
• Offer the plan-covered supply option as an alternative to reduce patient out-of-pocket costs
