CO-144: Incentive Adjustment for Preferred Product/Service

What Does CO-144 Mean?

CO-144 is the primary pairing for this code. The CO group code means the incentive adjustment is a contractual provision — the provider's contract with the payer includes incentive terms for preferred products, and the payment reduction is applied per those terms. The adjusted amount cannot be billed to the patient. The provider either accepts the reduced payment for non-preferred products or ensures correct documentation for preferred products to receive the full incentive rate.

CARC 144 is used when payers adjust claim payments based on incentive provisions that reward the use of preferred products or services. These incentive programs are common in pharmacy, DME, and clinical supply chains — payers negotiate preferred pricing with specific manufacturers or suppliers, and providers who use those preferred products receive higher reimbursement. When a non-preferred product is used, the payer reduces payment by the incentive differential, which is communicated through CARC 144.

This code is most commonly paired with Group Code CO, indicating the incentive adjustment is a contractual matter and the provider cannot bill the patient for the adjusted amount. The adjustment is not a denial — the claim is processed and paid, but at a lower rate because the preferred product incentive does not apply. In some cases, the provider may have used the preferred product but failed to document it correctly on the claim, causing the payer to apply the non-preferred rate by default.

From a financial perspective, CARC 144 adjustments can accumulate significantly over time, especially in high-volume practices that frequently use products covered by incentive programs. Understanding which products are preferred by each payer and ensuring correct documentation can materially affect reimbursement rates. When a non-preferred product is clinically necessary, providers should document the medical rationale and submit to the payer for exception consideration.

Common Causes

How to Resolve

Verify whether the preferred product was used, check the incentive program terms, and resubmit with correct documentation if the preferred product was used but not properly identified on the claim.

1. Check preferred product status Verify the payer's current preferred product list and determine if the product used qualifies for the incentive rate.
2. Correct documentation if needed If the preferred product was used, ensure the claim includes the correct NDC code, HCPCS code, and manufacturer identifiers. Resubmit with corrections.
3. Request clinical exception If a non-preferred product was clinically necessary, submit a medical necessity justification to the payer and request an exception to the incentive reduction.
4. Review contract incentive terms Review the contract to understand the full incentive structure, including any volume thresholds or quality criteria that affect incentive eligibility.

How to Prevent CO-144

• Keep a current copy of each payer's preferred product list and make it available to clinical staff when product decisions are made
• Include correct product identifiers (NDC, HCPCS, manufacturer) on all claims involving incentive-eligible products
• Train clinical and billing staff on payer incentive program criteria so preferred products are selected and documented correctly
• Monitor CARC 144 adjustments regularly to assess the financial impact and determine if switching to preferred products is appropriate

General Prevention

• Maintain a current copy of each payer's preferred product/service list and ensure clinical staff have access to it when making product or service decisions
• Train clinical and billing staff on the payer's incentive program criteria so preferred products are selected and coded correctly from the start
• Include the correct product identifiers (NDC codes, HCPCS codes, manufacturer information) on claims to ensure the incentive is properly applied
• When a non-preferred product must be used for clinical reasons, proactively document the medical necessity in the patient record and on the claim
• Review payer contracts periodically to stay informed of changes to incentive program terms, preferred lists, and qualifying criteria
• Monitor claims for incentive adjustments to detect patterns and adjust purchasing or prescribing practices as needed
