CA Lab Code Section 4661

Where an injury causes both temporary and permanent disability, the injured employee is entitled to compensation for any permanent disability sustained by him in addition to any payment received by such injured employee for temporary disability.

Every computation made pursuant to this section shall be made only with reference to disability resulting from an original injury sustained after this section as amended during the 1949 Regular Session of the Legislature becomes effective; provided, however, that all rights presently existing under this section shall be continued in force.
