CO-45 Denial Code: Charge Exceeds Contracted Amount
Key Takeaways
- What CO-45 Denial Code Covers: This code indicates that the charge submitted exceeds the allowable amount defined in the contract with the payer. It typically arises from discrepancies between billed amounts and the contracted rates.
- Common Scenarios That Trigger It: Scenarios include billing for services that are not covered or overbilling for procedures where the contracted rate is lower. For example, a facility may bill for a higher level of care than agreed upon.
- Who Should Address the Denial: The responsibility typically falls on the billing department, coding professionals, and sometimes the provider who rendered the service. Each plays a role in ensuring claims are submitted correctly.
- Best Practice for Proper Use: Always confirm the contracted rates with the payer before billing and ensure that the coding accurately reflects the services provided to minimize the chances of exceeding allowable amounts.
- Example of Actual Usage: A patient received an MRI, and the facility billed $2,000. However, the contract with the payer allowed for $1,500. The claim was denied with a CO-45 code, indicating the charge exceeded what was allowed.
What is CO-45 Denial Code
The CO‑45 denial code signifies that the charge submitted for a service exceeds the allowable amount specified in the provider's contract with the payer. This can occur when the billed amount is higher than what the insurance company has agreed to pay based on negotiated rates. Understanding this code is essential for healthcare providers and billing professionals as it directly impacts reimbursement and cash flow.
Payers trigger the CO‑45 denial code when they identify discrepancies between the billed amount and the allowable rate. The resolution of such denials often requires a thorough review of the contract terms and a careful assessment of the services billed, ensuring that providers adhere to the agreed‑upon pricing structures.
Common Reasons for Denial
Denial codes frequently reflect recurring process issues that can complicate billing and reimbursement. Understanding these root causes can help prevent future occurrences.
Root Cause | Description | How It Triggers CO-45 Denial Code | Suggested Fix |
|---|---|---|---|
Overbilling | Billing for services at a higher rate than the contracted amount. | When billed amount exceeds contractual limits, CO-45 is triggered. | Review and adjust billed charges to align with contracted rates. |
Incorrect Coding | Using codes that do not accurately reflect the services provided. | Inaccurate codes may lead to higher billed amounts than allowed. | Ensure accurate coding practices and regular training for coding staff. |
Failure to Pre-Authorize | Not obtaining pre-authorization for services that require it. | Claims may be denied due to lack of authorization, sometimes leading to CO-45. | Implement a system to track and manage pre-authorizations effectively. |
Who Can Resolve CO-45 Denial Code?
The resolution of a CO‑45 denial code typically involves collaboration between several roles within the healthcare organization:
- Billing Department: Responsible for submitting claims and addressing denials.
- Coding Professionals: Ensure claims are coded accurately and reflect the services provided.
- Healthcare Providers: May need to provide documentation or clarification for services rendered.
How to Resolve CO-45 Denial Code
Resolving a CO‑45 denial requires a systematic approach to ensure compliance and accuracy:
- Verify the Denial Reason: Contact the payer to confirm the specifics of the denial. Example: Verified missing prior authorization with Cigna.
- Correct and Refile the Claim: After identifying the error, fix it and resubmit the claim. Example: Added required modifier and sent via clearinghouse.
- Submit an Appeal with Documentation: If the denial persists, appeal with supporting documents. Example: Attached treatment notes and letter of medical necessity.
- Update Internal Processes: Implement changes to prevent future denials. Example: Set EHR reminder for pre-auth for all sleep studies.
Financial Impact of CO-45 Denial Code
Potential Lost Revenue | Average Time to Resolve | Staff Hours Involved | Frequency by Payer Type |

Common Mistakes to Avoid with CO-45 Denial Code
Mismanagement of CO‑45 denials can lead to claim rejections, delayed payments, and potential audits. Below are common mistakes to watch for:
- Ignoring Payer Contracts: Failing to review contracts can lead to overbilling. For example, a billing specialist may bill for a service unaware of the negotiated rate.
- Inaccurate Coding: Using incorrect diagnosis or procedure codes can trigger this denial. Coders might mistakenly select a code that does not match the service provided.
- Neglecting Pre-Authorization: Not obtaining necessary pre-authorizations can lead to denials. An office might schedule a procedure without confirming it requires prior approval.
