OPINION OF THE COURT
This workers’ compensation appeal concerns the type of prima facie showing that KRS 342.125(l)(d) requires in order to grant a motion to reopen and order further proof to be taken. The Court of Appeals determined that the claimant failed to make an adequate prima fade showing; that it was erroneous to grant her motion and subsequently increase her award; and that the error was unfairly prejudicial to the employer because KRS 342.125(8) barred a subsequent motion to reopen. On that basis, the court reversed a two-to-one decision of the Workers’ Compensation Board (Board), which held that the Administrative Law Judge (ALJ) erred by granting the motion but that the error was harmless. We affirm.
The claimant injured her back while working for the defendant-employer on December 31, 1984. The parties later agreed to settle the claim for a lump sum that represented a 35% permanent partial disability, apportioned 2/3 to the employer and 1/3 to the Special Fund. On June 30, 1987, an ALJ approved the agreement, which described the nature of the claimant’s injury as being a herniated disc at L4 on the left.
On December 12, 2000, the claimant filed a pro-se motion to reopen in which she alleged a “change of disability shown by objective medical evidence.” Accompanying the motion were various documents, including the claimant’s affidavit and a copy of the settlement agreement. She averred that her condition had worsened, that she now experienced numbness in her left leg and foot, that her ankle and knee hurt more than previously and would “give way,” and that she anticipated “the Doctor will increase my disability rating when he examines me on my next appointment.” Appended to the motion to reopen was a motion to hold the case in abeyance. As grounds for this second motion, the claimant stated that her condition had worsened, that she continued to require medical attention and that she anticipated that her doctor would increase her disability rating based on her worsening condition.
A May 24, 1999, report from Dr. Davies indicated that a recent MRI revealed what appeared to be a small fragment of recurrent disc at L4-5 on the left as well as scarring that indented the cal sac at that level. 1 Although there was less pain than on a previous visit, there was still some numbness and bilateral weakness of dorsi-flexion; positive straight leg raising on the left (about 30 degrees); unrestricted straight leg raising on the right; forward flexion of 20-30 degrees. Dr. Davies pre *499 scribed a dose pack and physical therapy, “to try to avoid repeat surgery if possible.”
Also submitted with the motion was a radiologist’s report, which indicated that a May 17, 1999, MRI revealed a disc fragment at L4-5. Another radiology report indicated that a lumbar spine x-ray revealed degenerative disc disease at L4-5. Finally, an emergency room admission report from April 17,1999, indicated that the claimant complained of low back pain and had a history of such pain since 1985.
On January 19, 2001, the employer filed an objection to the motion to reopen on the ground that it failed to make the
’prima facie
showing required by KRS 342.125(l)(d).
Stambaugh v. Cedar Creek Mining Co.,
On March 25, 2002, the employer renewed its motion to dismiss, stating that the claimant had failed to submit any evidence although more than a year had passed since the claim was placed in abeyance. In the alternative, the employer requested an order requiring the claimant to show cause why her motion to reopen should not be dismissed for failure to submit objective medical evidence to support it. On April 15, 2002, the Chief ALJ gave the claimant 30 days to show cause why the motion should not be dismissed for failure to submit any objective evidence in support of her position. Again acting prose, the claimant filed numerous bills pertaining to medical treatment she received between 1999 and 2001 and ■ also some medical records pertaining to the treatment. The Chief ALJ noted the filing, removed the claim from abeyance on May 24, 2002, and overruled the motion to dismiss. A subsequent order scheduled the taking of further proof. Sometime thereafter, the claimant obtained counsel.
In resisting the claim for additional benefits, the employer asserted among other things that the motion to reopen failed to show the requisite change of condition and that reopening was barred by limitations. An ALJ determined, however, that the claimant experienced a post-settlement change of condition and an increased impairment due to her injury. Furthermore, the changes resulted in total disability and occurred before the period of limitations expired. See KRS 342.125(8).
Workers’ compensation is statutory. Although the principles of the finality of judgments apply to final workers’ compensation awards, KRS 342.125 permits an award to be amended prospectively due to certain post-award changes.
Beale v. Faultless Hardware,
(d) Change of disability as shown by objective medical evidence of worsening or improvement of impairment due to a condition caused by the injury since the date of the award or order.
KRS 342.125(8) limits the period for reopening a claim that was decided before December 12, 1996, to within four years after December 12,1996.
In

Co. v. Tolliver,
The
Stambaugh
court described what it envisioned as being “a reasonable prima facie preliminary showing of the existence of
a substantial possibility of the presence of one or more of the prescribed conditions
” from KRS 342.125 before an adversary would be put to the expense of re-litigation.

Id.,
A worker’s right to increased benefits at reopening vests on the date that a motion to reopen is filed. '
Johnson v. Gans Furniture Industries, Inc.,
The claimant filed her motion to reopen on December 12, 2000. On January 18, 2001, the ALJ placed the matter in abeyance. On January 19, 2001, the employer filed its response to the motion, without objection. On January 26, 2001, the ALJ amended the previous order, granted the motion to reopen, and placed the reopened claim in abeyance. In the subsequent proceeding on the merits, the employer continued to assert that the claimant’s motion failed to make the neees-
*501
sary
prima facie
showing. Although she asserted, among other things, that the employer’s January 19, 2001, response to her motion was untimely, she failed to raise the argument subsequently when defending the award before the Board. Under the circumstance, it is not preserved for our review.
Smith v. Dixie Fuel Co.,
The claimant’s motion was premised on an allegation that she experienced a post-award change of disability as shown by objective medical evidence of a worsening of impairment. KRS 342.125(l)(d). Evidence of a worsening of impairment requires that there be a comparison of impairment at two points in time. The record before the ALJ on January 26, 2001, included medical evidence that addressed the claimant’s condition in May, 1999, when Dr. Davies began treating her. That evidence did not permit her impairment in 1987 to be compared with her impairment in December, 2000, when she filed her motion to reopen. Under the circumstances, it was an abuse of discretion to grant the motion. Furthermore, the decision was prejudicial to the employer because KRS 342.125(8) would have barred a subsequent motion to reopen.
The decision of the Court of Appeals is affirmed.
Notes
. It was later shown that Dr. Davies began treating the claimant in May, 1999.
. The applicable version of KRS 342.125 listed change of conditions, mistake, and fraud as being the grounds for reopening.
. In deciding that the ALJ erred in granting the motion to reopen but that the error was harmless, the Board relied upon an unpublished Supreme Court decision. The Court of Appeals later distinguished the decision, pointing out that the employer failed to raise a limitations argument. CR 76.28(4)(c) prohibits unpublished decisions from being “cited or used as authority in any other case in any court of this state.” For that reason, we have disregarded those portions of the parties’ briefs and the Court of Appeals' opinion that cite an unpublished decision or use it as authority.
