(a) The power and jurisdiction of the commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable, over each case is continuing and the commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable, may, in accordance with the provisions of this section and after due notice to the employer, make modifications or changes with respect to former findings or orders that are justified. Upon and after February 2, 1995, the period in which a claimant may request a modification, change or reopening of a prior award that was entered either prior to or after that date shall be determined by the following subdivisions of this subsection. Any request that is made beyond that period shall be refused.

1. (1) Except as provided in section twenty-two of this article, in any claim which was closed without the entry of an order regarding the degree, if any, of permanent disability that a claimant has suffered, or in any case in which no award has been made, any request must be made within five years of the closure. During that time period, only two requests may be filed.
2. (2) Except as stated below, in any claim in which an award of permanent disability was made, any request must be made within five years of the date of the initial award. During that time period, only two requests may be filed. With regard to those occupational diseases, including occupational pneumoconiosis, which are medically recognized as progressive in nature, if any such request is granted by the commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable, a new five-year period begins upon the date of the subsequent award. With the advice of the health care advisory panel, the executive director and the board of managers shall by rule designate those progressive diseases which are customarily the subject of claims.
3. (3) No further award may be made in fatal cases except within two years after the death of the employee.
4. (4) With the exception of the items set forth in subsection (d), section three of this article, in any claim in which medical or any type of rehabilitation service has not been rendered or durable medical goods or other supplies have not been received for a period of five years, no request for additional medical or any type of rehabilitation benefits shall be granted nor shall any medical or any type of rehabilitation benefits or any type of goods or supplies be paid for by the commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable, if they were provided without a prior request. For the exclusive purposes of this subdivision, medical services and rehabilitation services shall not include any encounter in which significant treatment was not performed.

(d) The commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable, has continuing power and jurisdiction over claims in which permanent total disability awards have been made after April 8, 1993.

1. (1) The commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable, shall continuously monitor permanent total disability awards and may, from time to time, after due notice to the claimant, reopen a claim for reevaluation of the continuing nature of the disability and possible modification of the award. At such times as the commission may determine, the commission may require the claimant to provide documents and other information to the commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable, including, but not limited to, tax returns, financial records and affidavits demonstrating level of income, recreational activities, work activities, medications used and physicians or other medical or rehabilitation providers treating or prescribing medication or other services for the claimant; require the claimant to appear under oath before the commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable, or its duly authorized representative and answer questions; and suspend or terminate any benefits of a claimant who willfully fails to provide the information or appear as required: Provided, That the commission shall develop, implement and complete a program as soon as reasonably possible that requires each person receiving permanent total disability benefits on the effective date of the amendment and reenactment of this section in the year 2003, and each person who is awarded those benefits thereafter, to submit the tax returns and the affidavit described herein at least once: Provided, however, That this requirement does not restrict the commission's authority to require the information that may be required herein at such other times as the commission may determine. The commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable, may reopen a claim for reevaluation when, in its sole discretion, it concludes that there exists good cause to believe that the claimant no longer meets the eligibility requirements under subdivision (n), section six of this article. The eligibility requirements, including any vocational standards, shall be applied as those requirements are stated at the time of a claim's reopening.
2. (2) Upon reopening a claim under this subsection, the commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable, may take evidence, have the claimant evaluated, make findings of fact and conclusions of law and shall vacate, modify or affirm the original permanent total disability award as the record requires. The claimant's former employer shall not be a party to the reevaluation, but shall be notified of the reevaluation and may submit any information as the employer may elect. In the event the claimant retains his or her award following the reevaluation, the claimant's reasonable attorneys' fees incurred in defending the award shall be paid by the Workers' Compensation Commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable. In addition, the Workers' Compensation Commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable, shall reimburse a prevailing claimant for his or her costs in obtaining one evaluation on each issue during the course of the reevaluation with the reimbursement being made from the fund. The board of managers shall adopt criteria for the determination of reasonable attorneys' fees.
3. (3) This subsection shall not be applied to awards made under the provisions of subdivision (m), section six of this article. The claimant may seek review of the final order as otherwise provided in article five of this chapter for review of orders granting or denying permanent disability awards.
4. (4) The commission shall establish by rule criteria for review, reopening and reevaluating a claim under this subsection. The commission shall at least quarterly provide a report of the exercise of its authority to continuously monitor permanent total disability awards under this section to the Joint Committee on Government and Finance and the Joint Commission on Economic Development.
