CO-240 Denials Explained: How to Identify, Appeal, and Prevent Them

Denials are a constant challenge for healthcare revenue cycle management (RCM) teams, but CO-240 denials are particularly troublesome due to their specificity. A CO-240 denial occurs when a diagnosis code is incompatible with the patient's documented birth weight, often requiring extensive rework and delaying reimbursement.

This blog will explain the CO-240 denial code in detail, highlight its impact on revenue cycle teams, and provide actionable steps to appeal and prevent such denials from disrupting your organization’s cash flow and operational efficiency.

What Is a CO-240 Denial?

The CO-240 denial code indicates that the diagnosis submitted with the claim is inconsistent with the patient’s birth weight. The prefix "CO" stands for Contractual Obligation, meaning the payer has determined the provider is responsible for the denial. This is typically due to a billing or documentation error, shifting the financial burden to the provider to resolve.

When faced with a CO-240 denial, providers must review the claim, verify the accuracy of the diagnosis and birth weight documentation, and submit corrections promptly.

Comparison: CO-240 vs Similar Denial Codes

Denial Code	Prefix Meaning	Reason/Description	Who's Financially Responsible
CO-240	Contractual Obligation	Diagnosis inconsistent with the patient’s birth weight	Provider
CO-16	Contractual Obligation	Claim lacks information or has missing/incorrect data	Provider
CO-22	Contractual Obligation	Services are deemed not medically necessary	Provider

The key difference with CO-240 lies in its specificity to birth weight and diagnosis mismatches, unlike CO-16, which covers general information errors, or CO-22, which pertains to medical necessity.

Common Causes of CO-240 Denials

1. Incorrect Diagnosis Code: The diagnosis code submitted does not align with the documented birth weight in the patient record.
2. Incomplete Clinical Documentation: Missing or unclear birth weight information in the medical record.
3. Claim Submission Errors: Errors during claim preparation, such as mismatched data or omission of critical information.
4. Outdated Coding Practices: Use of outdated or incorrect coding standards that do not comply with payer policies.
5. Payer-Specific Guidelines: Failure to adhere to specific payer requirements for claims involving neonatal diagnoses.

Impact on Revenue Cycle Teams

CO-240 denials can have far-reaching consequences for both financial and operational performance in healthcare organizations:

Financial Impact:
- Loss of revenue from denied claims requiring corrections and resubmissions.
- Increased accounts receivable days, delaying cash flow.
- Risk of claim write-offs if appeals are unsuccessful or deadlines are missed.
- Higher costs due to additional resources allocated for denial rework.

Operational Impact:
- Time-intensive denial resolution processes divert staff from other critical tasks.
- Coordination challenges between billing, coding, and clinical teams to resolve documentation issues.
- Need for specialized knowledge of payer-specific requirements and neonatal coding.
- Increased tracking and reporting to identify denial trends and improve processes.

Steps To Appeal a CO-240 Denial

Resolving a CO-240 denial requires a systematic approach to ensure accuracy and compliance:

Step 1: Review the Denial Notice
Carefully examine the Explanation of Benefits (EOB) or remittance advice to confirm the denial reason and identify any accompanying policy references.

Step 2: Gather Documentation
Collect all relevant clinical documentation, including the patient’s birth weight and diagnosis records, to verify accuracy and support the claim.

Step 3: Verify Eligibility
Cross-check the patient’s eligibility and payer-specific guidelines to ensure compliance with their policies.

Step 4: Prepare Appeal Letter
Draft a clear, concise appeal letter that outlines the denial reason, provides corrected information, and includes all supporting documentation.

Step 5: Submit Within Deadline
Ensure the appeal is submitted within the payer’s deadline, typically 30-60 days from the denial date, to avoid forfeiting reimbursement.

Step 6: Track and Follow Up
Monitor the appeal’s status with the payer and follow up regularly to ensure timely resolution.

How To Prevent CO-240 Denials

Preventing CO-240 denials requires proactive measures across all stages of the revenue cycle.

Front-End Prevention

• Thorough Patient Intake: Collect complete and accurate patient information during registration, including neonatal details like birth weight.
• Eligibility Verification: Use automated tools to verify coverage and identify payer-specific requirements before claim submission.
