Subrogation Recovery and the Mod: When Your Carrier Gets Paid Back
When a carrier recovers claim costs from a subcontractor's policy, does that recovery reduce the general contractor's actual losses on the NCCI worksheet? The answer depends on timing and the source of the recovery.
Subrogation recovery occurs when a carrier pays a WC claim on behalf of the insured employer and recovers all or part of the cost from a liable third party, often a subcontractor's carrier. Whether that recovery reduces the claim values on the employer's NCCI worksheet depends on when the recovery happens, whether NCCI's retroactive adjustment rules apply, and how the carrier reports the recovery.
Subrogation in workers' compensation works differently than in general liability. In WC, the carrier pays the claim regardless of fault. The injured worker gets compensated. The employer's experience rating counts the claim in actual losses. That is the starting point.
If the carrier later recovers from a third party, which in construction is often another carrier covering the subcontractor whose operations produced the injury, the carrier's net claim cost drops. The recovery is real money. What is less clear is whether the recovery reduces the actual losses that appear on the employer's NCCI worksheet.
How NCCI treats subrogation recovery
NCCI's experience rating plan uses actual losses as reported by the carrier. Actual losses include claim payments, allocated loss adjustment expenses, and reserves for open claims. When a carrier pursues subrogation and recovers funds, the net cost of the claim changes. The question is whether the carrier reports the claim to NCCI at the gross value or at the net value after recovery.
In practice, carriers report the gross claim value when the claim is first recorded. The reserve is set at the estimated total cost. Subrogation recovery, when it occurs, may be reported as a separate transaction or may not be reflected in the experience rating data at all, depending on how the carrier's claim system handles third-party recoveries under NCCI reporting rules.
NCCI's unit statistical reporting instructions treat subrogation recoveries as a reduction to incurred losses, but only when the recovery is recognized as a loss adjustment. If the carrier classifies the recovery under a different accounting code or as a general business recovery rather than a claim-specific adjustment, the recovery may never flow through to the experience rating data NCCI receives.
The timing problem
The most common pattern in construction subrogation is delayed recovery. A GC's carrier pays a claim from an injury that occurred on a subcontractor's worksite. The carrier reserves the claim at full value. The claim appears on the GC's NCCI worksheet at that full reserved amount. Subrogation against the subcontractor's carrier proceeds separately, often over months or years. By the time the recovery is finalized, the claim may have already been included in two or three annual mod calculations at the gross value.
If the recovery is reported as a reduction to incurred losses, NCCI will apply the adjustment retroactively. But the mechanism is slow. The carrier must file a corrected unit statistical report. NCCI must process the revision. The revision then feeds into the next mod calculation, which may not fully offset the impact of the higher gross values that appeared in the intervening years.
In our reviews of Southeast contractor worksheets, subrogation-related discrepancies typically appear as a gap between what the worksheet shows and what the carrier's internal records say. The worksheet shows a $75,000 claim. The carrier's claims system shows $55,000 net after recovery. The GC's mod was calculated on the full $75,000 for two years. The recovery adjustment has not yet been processed.
The contractual path
Some GCs address this through contractual requirements on subs. The subcontract agreement may require the sub to indemnify the GC for WC losses, either through direct payment or through a waiver of subrogation endorsement on the sub's policy. When the waiver is in place, the sub's carrier agrees not to subrogate against the GC, which is the opposite direction. The indemnity provision, when enforceable, creates a contractual right of recovery that sits outside the WC system entirely. The GC's carrier does not pursue the sub. The GC pursues the sub contractually for the premium impact of the claim.
Contractual recovery does not flow through NCCI's experience rating data because it is not a carrier-to-carrier transaction. It is a separate commercial claim between the GC and the sub. The GC receives the recovery as a business payment, not as a WC claim adjustment. The claim on the NCCI worksheet remains at the gross value. The recovery offsets the premium impact indirectly, through the GC's cash flow, rather than directly through the mod.
What an audit would check
An audit reviews the actual losses on your worksheet against the carrier's current claim status, including any subrogation recoveries posted to individual claim files. If a recovery has been processed on the carrier side but has not been reflected in the NCCI data sent for experience rating, the audit flags the discrepancy and initiates a corrected unit statistical report filing with NCCI. The delay between recovery and NCCI update is the gap that corrections can close.
