OPINION
This appeal is from a judgment on a subrogation claim brought by an employer and its workers’ compensation insurer against a third-party tortfeasor after a Naig settlement was entered into between the injured employee and the tortfeasor. Appellants contend the verdict of permanent disability was not supported by the evidence, and that the judgment improperly included a sum for workers’ compensation benefits payable in the future. We affirm.
FACTS
On February 11, 1978, Robert Thomas was driving a tractor-trailer owned by his employer, Dahlman, Inc., on an interstate highway near Columbus, Montana. Behind Thomas was appellant William Haase, driving his own tractor-trailer, which was leased to appellant Pirkle Refrigerated Freight Lines (hereafter, Pirkle). As Thomas drove down a hill, he entered a “white out” caused by a snowplow, which severely limited visibility. Shortly thereafter, the Haase truck entered the same area and struck the rear of Thomas’ rig.
Several actions ensued. The issues on this appeal arise out of respondent Aetna’s workers’ compensation payments to Thomas, and its subrogation claim against appellants Haase and Pirkle.
On the second day of the trial of Thomas’ negligence claim against Haase and Pirkle, these parties agreed to a settlement for $100,000, pursuant to a
Naig
release preserving the subrogation claim of Thomas’ employer, Dahlman, and Aetna, its workers’ compensation insurer.
Naig v. Bloom-ington Sanitation,
Appellants claim that the $80,000 agreement was brought before a settlement judge in the workers’ compensation division during the course of trial. Appellants claim they did not have an opportunity to participate in the settlement approval hearing. See Minn.Stat. § 176.521, subd. 2 (1978).
The $80,000 settlement was finalized on November 22, 1983, the second day of trial. Aetna then sought to amend its complaint to add a subrogation claim for the lump-sum settlement for future benefits. The trial court allowed this amendment, over Haase’s objection.
The jury returned a verdict finding Haase negligent, and his negligence 100% responsible for the collision. It found that all of Thomas’ lost wages and medical expenses from the time of his spinal fusion were the result of the collision. Finally, the jury found a 27% permanent partial disability to the back, 30% to the left arm, and 10% to the right arm, and found that the 51-year-old Thomas would be incapable of undertaking substantial gainful activity for a period of 14 years.
The trial court awarded judgment to Aet-na against Haase and Pirkle for past workers’ compensation benefits, and for the $80,000 lump-sum settlement for future benefits. It found that amount a reasonable present value for future benefits payable over the 14 years’ disability found by the jury.
Haase’s motion for post-trial relief was denied, except that the court corrected the judgment to delete reimbursement for compensation paid to Thomas during a 10-month layoff found by the jury not to have been caused by the accident.
ISSUES
1. Did Aetna’s statutory subrogation claim include a claim for workers’ compensation benefits payable in the future?
2. Did the trial court err in allowing Aetna to amend its complaint on the second day of trial to incorporate the claim for future benefits?
3. Was there sufficient evidence to support the jury’s conclusion that Thomas would be incapable of performing any substantial gainful activity for 14 years?
4. Did the trial court properly award $80,000 to Aetna on its subrogation claim for future benefits?
ANALYSIS
I.
The key question on appeal is whether the court erred in awarding Aetna a sum for future workers’ compensation benefits payable to Thomas. The trial court in awarding this sum applied Minn. Stat. § 176.061, subd. 10 (Supp.1983), allowing employers and insurers a right of indemnity for workers’ compensation benefits “paid or payable.” Subdivision 10 was added by an amendment effective July 1, 1983, five years after the injury but before the date of trial. We do not find this subdivision applicable, but conclude that prior law gave Aetna a subrogation claim for future benefits.
Prior to 1983, reimbursement of the employer from a tortfeasor for workers’ compensation benefits was governed by Minn. Stat. § 176.061, subds. 5, 6 (1978). Subdivision 5 outlines the procedures in bringing the third-party action, and gives the employer or its insurer a subrogation right to the employee’s claims. Subdivision 6 outlines the formula for splitting a third-party award won by the employee against a tort-feasor. The employee receives about Vs of the third-party recovery, and the employer receives most of the remainder to reimburse it for workers’ compensation paid. Any balance remaining from the judgment is paid to the employee and acts as a “credit” to the employer for benefits that may be paid in the future.
Appellants contend that this “credit” mechanism for splitting an award between the employee and his employer or its insurer is the sole means of providing *315 reimbursement for workers’ compensation benefits payable in the future. We conclude that a Naig settlement supersedes the scheme for allocation of the third-party recovery established in subdivision 6, including the credit for future benefits, and that the employer or its insurer must be allowed to recover those benefits as part of its subrogation claim.
This result was forecast in
Lang v. William Bros. Boiler & Manufacturing Co.,
The supreme court has followed
Lang
in two recent decisions involving settlements of third-party actions. In
Aetna Life & Casualty v. Anderson,
Here the employee, Thomas, settled only for those claims which were not recoverable under workers’ compensation. Thus, Aetna has no right to any share of the settlement through the workers’ compensation allocation scheme, including a credit for future payments, Minn.Stat. § 176.061, subd. 6. Thomas also waived any share of a future recovery made by Aetna under the workers’ compensation laws, thus eliminating any prospect of a statutorily-allocated settlement.
An employer or insurer who pays workers’ compensation benefits is subro-gated to the claims of its employee against a third-party tortfeasor. Minn.Stat. § 176.-061, subd. 5. Impairment of future earning capacity is an item of general damages recoverable in a tort action,
Capriotti v. Beck,
Appellants contend that the lump-sum settlement between Thomas and Aet-na was not in accord with the policy of the workers’ compensation system favoring continuing compensation. This argument could have been raised by intervention in the workers’ compensation case. In the tort action, however, a lump-sum award for future damages was entirely appropriate.
See Wilken,
A third-party tortfeasor’s interest in the workers’ compensation system is solely that of limiting its liability to its established fault.
Lambertson v. Cincinnati Corp.,
II.
The trial court allowed Aetna to amend its complaint to add the subrogation claim for $80,000 of future compensation benefits. The trial court noted that appellants were necessarily prepared to defend a future benefits subrogation claim since they would have had to defend Thomas’ claims regarding loss of future earning capacity. Appellants argue that the addition of the subrogation claim during trial was an abuse of discretion.
Generally, it is within the trial court’s discretion to allow an amendment to the complaint during trial.
Peterson v. Bishop,
III.
Appellants argue that there was insufficient evidence to support the jury’s verdict that Thomas would be unable to work for 14 years.
A jury verdict will be upheld unless it is manifestly contrary to the evidence.
Levienn v. Metropolitan Transit Commission,
Thomas did continue to work after the accident, but only due to the accommodation of his employer. His medical problems increased until he could only drive two hours at one time. In 1980, his physician, a certified neurologist, told him he was no longer capable of truck driving. Even after his cervical fusion operation, the doctor advised Thomas not to return to truck driving.
Appellants also claim the court erred by submitting to the jury the question of the degree of Thomas’ disability because the only expert asked provided an expert opinion as to degree of permanent disability. It has been held, however, that medical testimony, although helpful, is not dispositive on the issue of disability.
Hosk-ing v. Metropolitan House Movers Corp.,
IV.
Appellants also object to the award of damages for future benefits on the grounds that the lump-sum settlement was entered into without appellants’ participation.
The workers’ compensation law gives the right to participate in settlement approval hearings to parties who have intervened in the case. Minn.Stat. § 176.521, subd. 2 (Supp.1983). Appellants may have had an interest permitting them to intervene, but failed to apply for intervention, despite having notice of Thomas’ workers’ compensation claim. See Minn.Stat. § 176.-361 (Supp.1983).
Appellants’ objections to the workers’ compensation lump-sum settlement misconstrue the nature of their liability to Aetna. Aetna’s claim was not indemnity for benefits paid to Thomas, but subrogation to the claims of Thomas against appel *317 lants. Thus, appellants have no complaint as to the manner or amount of the lump-sum settlement as long as that amount did not exceed the damages recoverable against them by Thomas for lost earning capacity.
The amount of damages, including loss of future earning capacity, is a question for the jury.
Young,
296 Minn, at 434-35,
DECISION
The trial court properly allowed a claim for workers’ compensation benefits payable in the future. There was no abuse of discretion in permitting Aetna to amend its complaint to incorporate this claim. The jury’s finding of permanent disability and the trial court’s award for future damages were supported by sufficient evidence.
Affirmed.
