A perfectly coded claim can still generate $0 in reimbursement if it reaches the payer one day late.
That’s the impact of a Timely Filing Limit (TFL) — the maximum time a payer allows providers to submit an initial claim after the Date of Service (DOS). Miss the deadline, and the claim is often denied with CO-29 (Timely Filing Exceeded), leaving little or no opportunity for payment.
Why It Matters
Imagine a practice submitting 500 claims per month with an average reimbursement of $180 per claim. If just 2% miss the filing deadline:
- 10 claims denied
- $1,800 lost in a month
- More than $21,000 in annual revenue at risk
For larger physician groups and hospitals, the financial impact can reach hundreds of thousands of dollars annually.
Typical Filing Limits
Timely filing limits vary by payer and contract, but common examples include:
Always verify the applicable payer contract or provider manual before submission, as deadlines vary by plan and state.
The Most Common Causes
Revenue is often lost because of:
- Delayed charge entry
- Coding backlogs
- Incomplete documentation
- Insurance eligibility issues
- Incorrect payer selection
- Unresolved clearinghouse rejections
Most timely filing denials are preventable.
Best Practices
High-performing RCM teams:
- Submit claims within 24–72 hours of charge entry
- Monitor clearinghouse rejections daily
- Track aging claims before filing deadlines
- Maintain an updated payer-specific TFL matrix
- Use dashboards and work queues to flag claims approaching expiration
The Bottom Line
Timely Filing Limits are more than administrative deadlines — they’re a critical revenue protection strategy. Every missed deadline directly affects cash flow, Days in A/R, write-offs, and overall financial performance.
