Okla. Stat. tit. 85A, § 85A-116: Awards for permanent disability

A. Awards for permanent partial disability shall be made

pursuant to Sections 45 and 46 of this act, less any sums previously

paid which the Workers' Compensation Commission may find to be a

proper credit thereon. When the award becomes final, the whole sum

or any unpaid portion thereof shall operate as a final adjudicated

obligation and payment thereof may be enforced by the claimant or in

case of the claimant's death, by the surviving beneficiary entitled

to the proceeds as provided in Section 47 of this act.

B. Awards for permanent total disability shall entitle the

claimant to receive weekly income benefits for the period prescribed

in this act. When an award for permanent total disability becomes

final, the accrued portion thereof shall operate as a final

adjudicated obligation and payment thereof may be enforced by the

claimant or in case of the claimant's death, by the surviving

beneficiary entitled to the proceeds as provided in this act.

Permanent total disability awards shall not be commuted to a lump-

sum payment.
