Closed Claims Only Help Your Mod If They Stay Closed
A $25,000 reserve swing on a single claim can move your mod enough to shift annual premium by five figures. The claim isn't closed until the court says it's closed.
A closed workers' comp claim only helps your experience modification rate if the settlement is legally final and reserves are zeroed on the carrier's records. In Tennessee, Rule 60 motions can reopen settlements long after approval, and a reopened claim means reserves come back onto your NCCI worksheet. A $25,000 reserve swing on a single claim can move a Southeast contractor's mod enough to change annual premium by five figures when manual premium exceeds $1 million (Orson Group audit data, 2.
A claim you think is closed might not be. And a claim that isn't closed is still sitting on your NCCI experience rating worksheet, inflating your mod, costing you premium you don't owe.
The Tennessee Supreme Court's decision in Webb v. A.O. Smith Corporation (No. M2022-01468-SC-R3-WC, decided October 2, 2024) is the latest reminder that settlement finality in workers' comp is not a paperwork formality. It is a live legal question, and when the answer shifts, your mod shifts with it.
The Webb decision and why finality matters
In Webb, the court addressed whether a trial court erred in setting aside a workers' compensation settlement under Tennessee Rule of Civil Procedure 60.02 (Tennessee Supreme Court, October 2024). Rule 60 allows a court to relieve a party from a final judgment or order under specific grounds: mistake, inadvertence, excusable neglect, fraud, or any other reason justifying relief. The court affirmed that trial courts have discretion to reopen settlements under Rule 60, meaning a settlement approval order is not always the last word.
For contractors, the mechanism is simple. A claim settles. The carrier closes the file and zeroes the reserve. Then a motion under Rule 60 reopens the settlement. The reserve comes back. It lands on your worksheet during the next experience rating cycle, and your mod climbs.
The Tennessee Supreme Court clarified the standard for reopening in Webb, but the broader principle applies across Southeast jurisdictions. Georgia, Alabama, and the Carolinas all have their own procedural mechanisms for setting aside settlements. The window varies. The risk does not.
The dollar math on a reopened reserve
Here is what a single reserve swing looks like on a real worksheet. A roofing contractor in the Southeast carries roughly $1.2 million in manual premium across roofing (class code 5551), framing (5606), and concrete (5223). The split point for the current experience period sits at $18,500 in most NCCI states. A claim that was medical-only at $8,000 gets converted to indemnity after a Rule 60 motion reopens it, and the carrier sets a new reserve at $33,000.
That $25,000 reserve swing crosses the split point. The excess portion hits the mod at a discounted rate, but the primary portion hits at full weight. On a worksheet with $1.2 million in manual premium, a single claim moving from $8,000 to $33,000 can shift the mod by 5 to 8 points depending on the total expected losses in the period (Orson Group audit data, 2026). Five mod points on $1.2 million in manual premium is roughly $6,000 to $9,000 in additional annual premium. Eight points pushes it past $12,000.
That is one claim. One motion. One reserve that came back from the dead.
The workflow that prevents it
The contractors who avoid this problem treat settlement closure as a process, not an event. The settlement approval packet is step one. MMI (maximum medical improvement) dates and impairment ratings need to be locked before the carrier closes the file. Form C-32 in Tennessee (the settlement agreement) and Form C-30A (the medical report supporting the settlement) have to be complete and consistent. If the impairment rating on the C-30A doesn't match what the carrier used to set the reserve, the settlement is vulnerable to a Rule 60 challenge.
Reserve closure is the back end. A carrier that zeroes the reserve but leaves the claim file open in its internal system hasn't actually closed anything. When NCCI pulls data for the unit statistical filing, it reads what the carrier reports. If the carrier hasn't formally closed the claim, the reserve stays on the worksheet.
In our reviews of Southeast contractor worksheets, the most common pattern is a claim that settled 14 to 18 months ago, got reopened under a procedural motion, and shows up on the current mod with a reserve the contractor thought was gone. The contractor didn't know because nobody told the CFO. The broker didn't know because the carrier didn't flag it. The mod went up at renewal and nobody could explain why.
High-rated trades feel it first
Roofing, framing, concrete, and electrical contractors carry some of the highest base rates in NCCI's classification system. A roofing class code in Tennessee can carry an expected loss rate above $15 per $100 of payroll (NCCI, 2026). When the base rate is that high, mod movement translates directly into premium. A contractor at a 1.15 mod paying $1.2 million in manual premium is paying $138,000 in mod-loaded premium above the base. Drop that mod to 1.07 through a corrected reserve, and the savings exceed $9,000 per year.
The medical-only vs. lost-time distinction matters here too. Medical-only claims carry a 70% reduction factor in the experience rating formula. A claim that crosses from medical-only into indemnity loses that reduction. The full reserve hits the mod. That is the swing that costs five figures.
What an audit would check
An audit checks whether every claim on your worksheet marked as closed actually has a zero reserve on the carrier's current records. It checks whether settlement documents are final under your state's procedural rules, not just approved. It checks whether MMI dates and impairment ratings are consistent across the settlement packet. And it checks whether any claim in your experience period has been reopened since the carrier last reported it to NCCI. Most contractors we review have at least one claim in one of these states. Most don't know it until the mod shows up wrong at renewal.
