Why Does the CO-45 Denial Code Occur?

Many reasons contribute to CO-45 denial. It can be a misunderstanding of contract terms between health insurance and the healthcare provider. Here is a list of reasons that cause CO-45 denial code: 

1. Provider-Billed Amount Exceeds Contracted Rate

The commonly occurring situation is when the provider’s bill exceeds the contracted rate with the insurance companies. Usually, insurance companies negotiate with the healthcare professionals the maximum amount they will pay for a service. However, if the provider submits the claim with a higher amount then the insurer with the claim denial using code CO-45 code. 

2. Incorrect Billing Codes

Sometimes the incorrect billing code also results in a CO-45 denial. So, if a wrong CPT ( Current Procedural Terminology) code or ICD (International Classification of Diseases) code is used the insurance will likely reject the claim assuming the amount has been exceeded. 

3. Bundling or Unbundling of Services

Most insurance companies bundle the services. In other words, the services are reimbursed to the provider in a group of services under a single payment. So, if a provider unbundles the services and submits separate claims then it will result in a CO-45 denial code. Because the bundled rate is lower than the unbundled rate the insurer will likely reject it because it exceeds the negotiated rate. 

4. Out-of-Network Providers

The reimbursement is significantly lower for out-of-network providers as compared to in-network providers. So, if the provider submits a bill at a higher rate it will possibly lead to a CO-45 denial code. 

5. Adjustments or Modifications to Contractual Rates

The provider must stay updated with the latest updates from the insurance companies. If the provider fails to do so it will likely result in CO-45-denial due to the billed amount being higher than the contractual amount.
