*73The plaintiff, Barbara Dahle, appeals from the decision of the Compensation Review Board (board), which affirmed the decision of the Workers' Compensation Commissioner for the Sixth District1 dismissing the plaintiff's claim that she was entitled to temporary total disability benefits without a social security offset. On appeal, the plaintiff claims2 that the board erred by: (1) not addressing past incorrect evidence, not *74finding her new evidence credible, and not addressing a statement from Commissioner Stephen B. Delaney about delayed medical care; and (2) denying her request for financial compensation without a social security offset pursuant to General Statutes (Rev. to 2003) § 31-307 (e).3 We disagree and, accordingly, affirm the decision of the board.
The following facts and procedural history are relevant to our resolution of this appeal. On August 8, 2003, the plaintiff suffered a compensable injury to *865her right shoulder and left hip after she fell during and in the course of her employment with the defendant The Stop & Shop Supermarket Company, LLC.4 Following treatment, Scott Organ, a physician, issued a 5 percent permanent partial disability rating as to the plaintiff's right upper extremity by report dated March 17, 2006. By voluntary agreement of the parties, dated September 5, 2006, the plaintiff was paid a 5 percent permanent partial disability5 of the right shoulder with a maximum medical improvement date of September 5, 2006. No *75permanency rating was ever issued as to the plaintiff's left hip.
A formal hearing took place before Commissioner Ernie R. Walker on June 3, 2008. The issues addressed at the hearing included the plaintiff's claim for wage differential benefits pursuant to General Statutes § 31-308a6 and her claim for additional medical treatment pursuant to General Statutes (Rev. to 2003) § 31-294d.7 On June 4, 2008, Commissioner Walker issued a decision (2008 commissioner's decision) in which he granted the plaintiff's request for § 31-308a benefits but denied her request for additional medical treatment pursuant to § 31-294d. Regarding the denial of additional medical treatment, the commissioner noted that he found credible the testimony of the plaintiff's treating physician, Organ, who testified at the hearing that it was his opinion that additional treatment would be palliative and not curative.
On June 18, 2008, the plaintiff filed a motion to correct the 2008 commissioner's decision, which was denied on June 19, 2008. On June 27, 2008, the plaintiff filed a *76petition for review of the 2008 commissioner's decision denying her request for additional medical treatment.
The petition for review was heard before the board on December 12, 2008. On June 5, 2009, the board affirmed the 2008 commissioner's decision, finding no error. Specifically, *866the board concluded, inter alia, that "the medical opinions in the ... record provide ample support for the determination by the ... commissioner that a pain management regimen would be palliative rather than curative and, thus, would not constitute reasonable or necessary treatment."8 The plaintiff did not appeal the June 5, 2009 decision of the board (2009 board decision).9
On April 18, 2011, the plaintiff requested approval from the Workers' Compensation Commission (commission) for surgery on her right shoulder. The request initially was denied. The plaintiff then underwent surgery on her right shoulder on September 17, 2014, for which she received total incapacity benefits pursuant to § 31-307, with an offset for social security benefits, as required by subsection (e) of that statute.
Formal hearings took place before Commissioner Delaney on April 27, May 8, and June 16, 2015, to address the plaintiff's claim that she was entitled to compensation without a social security offset, and that the 2008 commissioner's decision and the 2009 board decision *77were incorrect.10 Specifically, the plaintiff "assert[ed] that delays in her requested medical treatment [had] caused her to be subject to the social security offset and, as a result of these delays, [the commissioner] may order [the defendant] to pay temporary total [disability] benefits at the full rate without regard to the [§] 31-307 (e) offset." On September 28, 2015, Commissioner Delaney dismissed the plaintiff's claim, having found that the plaintiff had failed to sustain her burden of proof that she was entitled to benefits without the offset. In his finding and dismissal (2015 commissioner's decision), the commissioner noted that from August, 2008, to May, 2013, approximately fifteen hearings took place regarding medical treatment and benefits, and the plaintiff was represented by counsel during these proceedings. Commissioner Delaney also noted that "[t]he ... commission authorized various physicians to treat/evaluate the [plaintiff] through this time period." On the basis of these findings, the commissioner rejected the plaintiff's equitable claim that, due to alleged negligence and errors in the handling of her case, her case was delayed and, thus, she was entitled to temporary total disability benefits without the social security offset.
On October 13, 2015, the plaintiff filed a petition for review of the 2015 commissioner's decision denying her request for benefits without the social security offset. On November 23, 2015, the plaintiff filed a motion to correct, which was denied on December 3, 2015.
The petition for review was heard before the board on April 29, 2016. On August 8, 2016, the board affirmed the 2015 commissioner's decision and rejected the plaintiff's equitable argument that a waiver of the offset *78should be granted (2016 board decision). *867The board noted that the commissioner had no authority to waive the offset. The board also noted that, "even if this tribunal could consider this case on the merits, we would find that many of the arguments raised by the [plaintiff] on appeal go to factual issues which an appellate panel such as ours cannot retry .... Moreover, many of the issues [the plaintiff] has raised go to the handling of her claim during the period prior to June 4, 2008, when Commissioner Walker issued a finding that the [plaintiff] subsequently appealed. We affirmed that [2008 commissioner's] decision. The [plaintiff] did not appeal our decision to the Appellate Court. We must now treat [the 2009 board] decision as final and as being the law of the case ...." (Citation omitted; internal quotation marks omitted.) This appeal followed.
We begin by setting forth our standard of review. "The principles that govern our standard of review in workers' compensation appeals are well established. The conclusions drawn by [the commissioner] from the facts found must stand unless they result from an incorrect application of the law to the subordinate facts or from an inference illegally or unreasonably drawn from them.... [Moreover, it] is well established that [a]lthough not dispositive, we accord great weight to the construction given to the workers' compensation statutes by the commissioner and [the] board. ... Cases that present pure questions of law, however, invoke a broader standard of review than is ordinarily involved in deciding whether, in light of the evidence, the agency has acted unreasonably, arbitrarily, illegally or in abuse of its discretion." (Internal quotation marks omitted.) Balloli v. New Haven Police Dept. , 324 Conn. 14, 17-18, 151 A.3d 367 (2016).

The plaintiff first claims that the board erred in not addressing past incorrect evidence and not finding her *79new evidence credible.11 Specifically, the plaintiff argues that "new (facts) evidence in the record ... establishes that the negligent and careless handling of her case since 2005 is the main factor in the years of waiting for her medical treatments and her return to full employment. The ... [b]oard erred by failing to acknowledge the new (facts) evidence that [the] plaintiff has submitted." The plaintiff further claims that the board erred in not addressing Commissioner Delaney's statement about delayed medical treatment. We disagree.
Because the plaintiff's claims relate to factual findings by the commissioner, we begin our analysis by reiterating that "[a]n agency's factual and discretionary determinations are to be accorded considerable weight by the courts." (Internal quotation marks omitted.) Pasquariello v. Stop & Shop Cos. , 281 Conn. 656, 663, 916 A.2d 803 (2007). "Once the commissioner makes a factual finding, [we are] bound by that finding if there is evidence in the record to support it." (Internal quotation marks omitted.)
*868Rodriguez v. E.D. Construction, Inc. , 126 Conn. App. 717, 726, 12 A.3d 603, cert. denied, 301 Conn. 904, 17 A.3d 1046 (2011).
As to the plaintiff's argument regarding "past incorrect evidence" and "new evidence," the board properly refused to address it in the 2016 board decision.12 The *80evidence that the plaintiff references pertains to factual findings and issues related to the 2008 commissioner's decision. As the board noted in its decision, "many of the arguments raised by the [plaintiff] on appeal go to factual issues which an appellate panel such as ours cannot retry ...." It is well established that "[n]either the ... board nor this court has the power to retry facts.... [O]n review of the commissioner's findings, the [board] does not retry the facts nor hear evidence. It considers no evidence other than that certified to it by the commissioner, and then for the limited purpose of determining whether or not the finding should be corrected, or whether there was any evidence to support in law the conclusions reached." (Internal quotation marks omitted.) Hummel v. Marten Transport, Ltd. , 114 Conn. App. 822, 842-43, 970 A.2d 834, cert. denied, 293 Conn. 907, 978 A.2d 1109 (2009). The board properly determined that it did not have the authority to "correct" findings from the 2008 commissioner's decision-a decision that had become final when the plaintiff did not appeal the 2009 board decision affirming the 2008 commissioner's decision-as the plaintiff requested that it do. Accordingly, we cannot conclude that the board erred in refusing to address the plaintiff's new evidence.13 *81As to the plaintiff's claim regarding the commissioner's alleged statement about delayed medical care, our review of the transcript demonstrates that the plaintiff quotes Commissioner Delaney out of context. The plaintiff argues that the "commissioner himself acknowledges [that the] plaintiff's medical treatment was delayed." Contrary to her position, Commissioner Delaney was simply paraphrasing what the plaintiff might include in the proposed findings that she was required to draft. Commissioner Delaney stated during the April 27, 2015 hearing: "Okay, I'm going to give you an opportunity to give me what we call [p]roposed [f]indings, and you can ask ... my paralegal [about the format] .... [Y]ou want me to take your evidence in the best light for you and [tell *869me] why I should find a, what's the word, I don't want to use the word because you don't like it, you don't like the word exception .... [So], why [§ 31-307 (e) ] is not applicable to you ... delay of medical treatment .... Somebody delayed your medical treatment and the system. I'm not going to ask you to write a [b]rief unless you'd like to ...." The plaintiff then stated that she would talk to the commissioner's paralegal about how to format the proposed findings. Commissioner Delaney, however, neither found nor opined that the plaintiff's treatment was delayed. Accordingly, we cannot conclude that the board erred by not acknowledging such a statement in its 2016 decision.
On the basis of the foregoing, we conclude that the board did not err by refusing to address the plaintiff's attempt to correct "past incorrect evidence" and introduce "new evidence" to prove that delays beyond her control made her subject to the offset.
*82II
The plaintiff next claims that the board erred in affirming the commissioner's denial of her request for financial compensation without the social security offset. Specifically, the plaintiff argues that she should have been awarded benefits without the social security offset set forth in § 31-307 (e) because errors and delays by the commissioner in 2008 and the board in 2009 resulted in a delay in obtaining compensation, which made her subject to the offset. The plaintiff essentially argues that, if not for the negligence of the commissioner and the board, she would have received her compensation benefits before she started receiving social security, and she, therefore, would not have been subject to the offset. The plaintiff further argues that the board erred in stating that she requested a waiver of the offset. We disagree.
Section 31-307 (e) provides: "Notwithstanding any provision of the general statutes to the contrary, compensation paid to an employee for an employee's total incapacity shall be reduced while the employee is entitled to receive old age insurance benefits pursuant to the federal Social Security Act. The amount of each reduced workers' compensation payment shall equal the excess, if any, of the workers' compensation payment over the old age insurance benefits." In 2006, the legislature, through "Public Acts 2006, No. 06-84, removed subsection (e) from § 31-307." Hummel v. Marten Transport, Ltd. , supra, 114 Conn. App. at 826 n.2, 970 A.2d 834. Although the offset was repealed, "[w]e look to the statute in effect at the date of injury to determine the rights and obligations between the parties." Id. Because the offset was in effect on August 8, 2003, the date of injury, the offset applies to the plaintiff's claim.
On appeal, the plaintiff does not contest that her age makes her subject to the social security offset. She also *83does not argue that the repeal of the offset applies retroactively. In fact, in her reply brief, the plaintiff clarifies that she "is not asking this court to ignore [§] 31-307 (e) and waive it. [She] did not request [that] the ... board ... waive ... the offset." Instead, the plaintiff argues that negligence in the handling of her case resulted in delays in treatment that made her subject to the offset, and that, as a result, she is entitled to financial compensation without the offset because it is not her fault that she is subject to the offset. Despite the plaintiff's argument to the contrary, her request for benefits without the offset is the functional equivalent of requesting a waiver of the offset. Accordingly, we reject her argument that the board *870erred in stating that she was requesting a waiver of the offset because she did, in effect, request a waiver even if that was not the exact language that she used.
As to her argument in favor of a waiver, a significant portion of the plaintiff's appellate briefs are dedicated to her claim that, due to the alleged negligence and carelessness of the commissioner in 2008 and the board in 2009, she is entitled to a waiver of the offset. To the extent that the plaintiff argues that her new evidence established negligence on the part of the commission that entitled her to a waiver of the offset, we reject that argument. As we previously concluded in this opinion, the board properly refused to address the plaintiff's new evidence in its 2016 decision. See part I of this opinion.
More importantly, the plaintiff has provided no authority, and we have found none, that permits the commissioner to waive the statutorily required social security offset. "The powers and duties of workers' compensation commissioners are conferred upon them for the purposes of carrying out the stated provisions of the Workers' Compensation Act.... It is well settled that the commissioner's jurisdiction is confined by the ... act and limited by its provisions." (Internal *84quotation marks omitted.) Frantzen v. Davenport Electric , 179 Conn. App. 846, 851, 181 A.3d 578, cert. denied, 328 Conn. 928, 182 A.3d 637 (2018). The plaintiff essentially concedes that nothing gives the commissioner the authority to waive the offset for her requested reasons, by stating in her principal brief that "[t]his appeal must set a precedent for the negligence and carelessness in the mishandling of [the] plaintiff's case." She further states in her reply brief to this court that she "is not suggesting that the commissioner has the power to order an employer to compensate a [plaintiff] for errors made by the commission."
On the basis of the foregoing, the plaintiff's claim must fail. Because both the commissioner and the board properly determined that there was no authority for the commissioner to waive the offset, we cannot say the board erred in denying the plaintiff's request for financial compensation without the offset.
The decision of the Compensation Review Board is affirmed.
In this opinion the other judges concurred.
