This is аn appeal from a decision of the Industrial Commission finding that claimant had failed to prove that his medical condition requiring back surgery was caused by an industrial accident rather than by the preexisting degenerative changes in his thoracic and lumbar spine. Because the Commission, as the trier of fact, is not required to accept *512 the testimony of the claimant’s treating physician, we affirm its decision.
I.
Factual Background
On March 4, 2008, Lloyd Fife (Claimant) filed a workers’ compensation complaint alleging that on February 22, 2008, while wоrking at The Home Depot, Inc. (Employer), he had injured his back while lifting a dryer to obtain it for a customer. Claimant sought medical care on February 25, 2008. His x-rays revealed severe degenerative changes in his thoracic and lumbar spine with disc narrowing, severе degenerative disc disease, and degenerative arthritis in the lower lumbar facet joints. His physician released Claimant with a fifteen-pound lifting restriction and referred him to a physical medicine and rehabilitation specialist.
Claimant cancellеd his appointment with that specialist and instead consulted with an orthopedic surgeon on March 3, 2008. A lumbar spine MRI showed spinal stenosis at L3-4, moderate narrowing of the foramina on L3-4, L4-5 and L5-S1, and moderate facet degenerative change and hypertrophy at L23, L3-4, L4-5, and L5-S1. The surgeon’s primary diagnosis was degenerative disc disease, and he recommended a five-level decompression and fusion to remedy a stenosis at L2. On March 11, 2008, Claimant underwent surgery consisting of a five-level (L2 to SI) decompression and fusion.
On March 26, 2008, National Union Fire Insurance Company of Pittsburgh (Surety) learned during a telephone conversation with Claimant that he had undergone the surgery. After obtaining medical records related to the surgery, Surety arranged for an independent medical examination of Claimant, which was done on June 19, 2008.
The physician who performed the independent medical examination concluded that Claimant’s need for surgery was not related to his industrial accident. The physician noted that the MRI did not show any evidence of acute injury, fracture, or dislocation consistent with an industrial accident or injury. Claimant’s surgeon opined that Claimant’s industrial accident was related to his need for surgery because it exacerbated his condition and Claimant felt an increase in symptoms which did not subside.
An evidentiary hearing was held before a hearing officer on November 5, 2009, but the hearing officer left the employment of the Industrial Commission before submitting proposed findings of fact and conclusions of law. The Commission then reviewed the record and issued its findings of fact, conclusions of law, and order on June 8, 2010. It found the testimony of Claimant’s surgeon unpersuasive, characterizing it as “unclear, to the point of opacity, as to the actual nature of the injury which he claims is responsible for thе need for surgery.” When the surgeon had been asked whether he could point to any objective pathological findings in any of the diagnostic studies he had performed on Claimant that relate to recent trauma, the surgeon answered that he could not. The Commission found convincing the testimony of the physician who conducted the independent medical examination of Claimant. That physician opined that in the absence of any objective evidence of injury, it was more likely that Claimant’s pain resulted from a nonspecific low back strain suffered as a result of lifting the dryer. In the physician’s opinion, Claimant’s surgery was wholly related to his preexisting condition and not to the low back strain caused by lifting the dryer.
The Commission concluded that Claimant had failed to prove that the medical condition for which he had surgery was causally related to the industrial accident or that the accident aggravated his preexisting degenerative condition. The Commission found that Claimant was only entitled to benefits for his initial medical visit on February 25, 2008. It denied benefits for his later medical treatment, including the surgery, and for any disability resulting from his surgery or degenerative disc disease. Claimant then timely appealed.
II.
Did the Industrial Commission Err as a Matter of Law in Not Accepting the Testimony of Claimant’s Physician?
On November 3, 1936, Article V, Section 9 of the Idaho Constitution was
*513
amended to provide that appeals from the Industrial Accident Board would go to this Court rather than to the district courts.
Mundell v. Swedlund,
Because we do not have jurisdiction to reweigh the evidence or rule upon the credibility of witnesses, arguments that appear to ask us to do so will be construed, if possible, as intending to raise an issue of law. If they cannot be so construed, they will not be addressed.

Page v. McCain Foods, Inc.,
Citing
Sprague v. Caldwell Transportation, Inc.,
As we stated in
Henderson v. McCain Foods, Inc.,
“One of the facts essential to the recovery of medical expenses is that the expenses were incurred as a rеsult of an industrial accident.”
The Commission did not question the reasonableness of Claimant’s surgery as a treatment for his medical condition. It simply *514 held that Claimant had failed to prove that the industriаl accident caused the condition for which Claimant underwent surgery. The Commission found that “the evidence fails to establish that the work accident contributed to the condition for which Claimant required multi-level back surgery. Claimant may have needed back surgery, but not for a work related injury.”
Claimant contends that the Commission erred as a matter of law in rejecting the testimony of his surgeon. Relying upon Sprague, the Claimant argues, “The Commission rejected Blaine Fife’s claim in part because ‘[the surgeon] was unable to identify any anаtomical findings that were likely related to the subject accident.’ The Commission demands a level of proof which this Court has never required.” (Quoting the Commission’s findings; emphasis in original; citation to record omitted.)
There is absolutely nothing in the
Sprague
opinion that supports this argument. As the
Sprague
Court stated, “The sole issue presented on this appeal is whether the treatment Sprague received from his physician subsequent to April 10, 1985, was ‘reasonable’ under I.C. § 72-432(1).”
“Worker’s compensation is not meant or intended to be life or health insurance; it is purely accident and occupational disease insurance.”

III.
Is the Commission’s Decision Supported by Substantial and Competent Evidence?
Claimant contends that the Commission’s decision is not supported by substantial and competent evidenсe, and he argues at length why the Commission should have believed his surgeon. “Because the Commission is the fact finder, its conclusions on the credibility and weight of the evidence will not be disturbed on appeal unless they are clearly erroneous. This Court does not weigh the evidence or consider whether it would have reached a different conclusion from the evidence presented.”
Gooby v. Lake Shore Mgmt. Co.,
The Commission found the testimony of the physician who performed the independent medical examination more pei'suasive than the testimоny of Claimant’s surgeon. Determining the credibility of the witnesses and the weight to give their testimony was the province of the Commission. The testimony of the physician who performed the independent medical examination was substantial and competent evidenсe supporting the Commission’s factual findings.
Claimant also challenges several factual findings by the Commission and its failure to make other findings. Claimant has not shown how any of those alleged errors ai’e relevant to anything regarding this appeal. Alleged errors regarding irrelevant facts are not a ground for setting aside the Commission’s order, and therefore they need not be addressed on appeal.
IV.
Is Claimant Entitled to an Award of Attorney Fees on Appeal?
Claimant also seeks an award of attorney fees on appeal pursuant to Idaho Code section 72-804. That statute mandates the award of attorney fees if the employer or surety contested a claim for compensation without a reasonable ground. Obviously, the employer and its surеty did not do so in this case. Therefore, Claimant is not entitled to an award of attorney fees on appeal.
V.
Conclusion
We affirm the order of the Industrial Commission, and we award respondents costs on appeal.
