What is CO-131 Denial Code

The CO‑131 denial code refers to "Negotiated Discount," indicating that the billed amount exceeds the allowed amount based on the provider's contract with the payer. This denial typically arises when the healthcare provider does not adhere to the contractual terms established with the insurance company. It affects reimbursement by reducing the amount the provider can collect for the service rendered.

When a claim is denied due to this code, it signifies a need for the provider to review their billing practices and ensure compliance with the negotiated rates. This denial can have payer‑specific implications, as some insurers may have varying thresholds for what constitutes a negotiated discount, necessitating a tailored approach to each payer's policies.

Common Reasons for Denial

Denial codes often reflect recurring process issues, making it essential for providers to understand the underlying causes to mitigate future occurrences.
