Don't Let CO 29 Denials Slow You Down: A Guide to Timely Filing

Receiving a CO 29 denial on a claim can be frustrating and impact your practice's bottom line. This code indicates that the claim was submitted after the insurance company's specified timeframe for filing. Understanding timely filing limits and taking proactive steps can help you avoid these denials.

Understanding Timely Filing Limits
Insurance companies establish specific timeframes, known as timely filing limits, for submitting claims. These limits vary depending on the insurance policy and are calculated from the date of service. While some payers allow a year or more, others have stricter deadlines of 90 or 120 days.

Common Timely Filing Limits:

• Medicare, United American Ins, Humana Medicare Advantage, Medicare Rail Road, Tricare: 1 year
• Aetna: 120 days
• Amerigroup: 180 Days for Participating Providers or 1 year for Non-Participating Providers
• Blue Cross Blue Shield (BCBS): 12 months based on provider contract
• Cigna, Kaiser Permanente, United Health Care, VA: 90 days
• Humana Commercial, Coventry, WellCare: 180 days
• Bankers Life: 15 months

Steps to Take When Facing a CO 29 Denial
If your claim is denied with a CO 29 code, consider the following steps:

• Verify Claim Submission Date: Double-check that the claim was submitted within the required timeframe.
• Justify Late Filing: If there was a valid reason for the delay, prepare a detailed explanation to accompany your appeal.
• Submit an Appeal with PDR: File an appeal along with a Provider Dispute Form (PDR) to formally contest the denial.

Preventing CO 29 Denials
To avoid CO 29 denials, implement these strategies:

• Track Timely Filing Limits: Maintain a system to track the timely filing limits for different insurers.
• Utilize Claim Submission Software: Consider using software that automates claim submission and includes timely filing reminders.
• Regularly Review Aging Claims: Monitor outstanding claims to identify those nearing the timely filing deadline.
• Stay Updated on Payer Guidelines: Keep abreast of any changes in timely filing limits or claim submission requirements.

By understanding timely filing limits and taking proactive steps, you can significantly reduce the occurrence of CO 29 denials and improve your practice's revenue cycle.
