(a) A permanent partial disability not scheduled in § 11-9-521 shall be apportioned to the body as a whole, which shall have a value of four hundred fifty (450) weeks, and there shall be paid compensation to the injured employee for the proportionate loss of use of the body as a whole resulting from the injury.

(b)

(1) In considering claims for permanent partial disability benefits in excess of the employee's percentage of permanent physical impairment, the Workers' Compensation Commission may take into account, in addition to the percentage of permanent physical impairment, such factors as the employee's age, education, work experience, and other matters reasonably expected to affect his or her future earning capacity.

(2) However, so long as an employee, subsequent to his or her injury, has returned to work, has obtained other employment, or has a bona fide and reasonably obtainable offer to be employed at wages equal to or greater than his or her average weekly wage at the time of the accident, he or she shall not be entitled to permanent partial disability benefits in excess of the percentage of permanent physical impairment established by a preponderance of the medical testimony and evidence.

(c)

(1) The employer or his or her workers' compensation insurance carrier shall have the burden of proving the employee's employment, or the employee's receipt of a bona fide offer to be employed, at wages equal to or greater than his or her average weekly wage at the time of the accident.

(2) Included in the stated intent of this section is to enable an employer to reduce or diminish payments of benefits for a functional disability, disability in excess of permanent physical impairment, which, in fact, no longer exists, or exists because of discharge for misconduct in connection with the work, or because the employee left his or her work voluntarily and without good cause connected with the work.

(d) In accordance with this section, the commission may reconsider the question of functional disability and change a previously awarded disability rating based on facts occurring since the original disability determination if any party makes application for reconsideration within one (1) year after the occurrence of the facts.

(e) In considering a claim for permanent disability, the commission and the courts shall not consider the odd-lot doctrine.

(f)

(1) Permanent total disability benefits shall be paid during the period of permanent total disability until the employee reaches the age of sixty-five (65); provided, with respect to permanent total disabilities resulting from injuries which occur after age sixty (60), regardless of the age of the employee, permanent total disability benefits are payable for a period of two hundred sixty (260) weeks.

(2) The purpose and intent of this subsection is to prohibit workers' compensation from becoming a retirement supplement.

(g) (1) (A) The commission, after a public hearing, shall adopt an impairment rating guide to be used in the assessment of anatomical impairment.

(B) The guide shall not include pain as a basis for impairment.

(2) The impairment rating guide adopted by the commission shall be subject to review by the General Assembly before April 1 of every odd-numbered year beginning with the regular session of 1999.
