CARC 131 - Claim Specific Negotiated Discount

What it means

This code indicates that the payer applied a discount to the claim based on a specific negotiated agreement, such as a contracted rate with the provider or a special arrangement tied to this particular claim. It's not a denial, but an adjustment reflecting an agreed-upon reduction in payment.

Common causes

Provider has a contracted or negotiated rate agreement with the payer that applies to this claim
Claim falls under a special pricing arrangement (e.g., value-based care contract, bundled payment, or single-case agreement)
Payer system applied a discount per the terms of a network or out-of-network negotiated agreement
Adjustment reflects a previously agreed-upon rate reduction for this specific service or encounter

How to fix it

Review the applicable contract or negotiated agreement to confirm the discount amount aligns with the terms
Verify the adjustment matches the expected rate under the specific arrangement referenced (e.g., single-case agreement, bundled rate)
Cross-check the remittance advice against your fee schedule or contract terms for this payer
If the discount seems incorrect or doesn't match your agreement, contact the payer's contracting or provider relations department for clarification
Document the specific negotiated agreement referenced for this claim in case of future audits or disputes

Appeal / resubmit

If you believe the negotiated discount was applied incorrectly or doesn't match the terms of your agreement, gather the specific contract or negotiated rate documentation and submit a written inquiry to the payer's contracting department. This is typically a contractual matter rather than a traditional appeal, so working with your practice's contracting or credentialing team may be more effective than a standard clinical appeal.

Frequently asked

Does CARC 131 mean my claim was denied?

No, this code reflects a contractual adjustment or discount, not a denial. The claim was processed, but a negotiated discount was applied to the payment amount.

Why would a claim have a 'specific' negotiated discount instead of a standard contract rate?

This often applies to unique arrangements like single-case agreements, out-of-network negotiations, or special contracts that apply only to particular claims or circumstances rather than your standard fee schedule.

Who do I contact if I think the discount is wrong?

Reach out to your payer's contracting or provider relations team, since this adjustment relates to a negotiated agreement rather than a standard claims processing issue.
