Article 7 - Schedule for Rating Permanent Disabilities
Section 9805.1 - Data Collection, Evaluation, and Revision of Schedule

(1) collect for 18 months permanent disability ratings under the 2005 Permanent Disability Rating Schedule (PDRS) effective for injuries occurring on or after 1/1/05 and effective for injuries occurring on or after 4/19/04 and before 1/1/05 where there has been either no comprehensive medical-legal report or no report by a treating physician indicating the existence of permanent disability, or when the employer is not required to provide the notice required by Labor Code Section 4601 to the injured employee;

(2) evaluate the data to determine the aggregate effect of the diminished future earning capacity adjustment on the permanent partial disability ratings under the 2005 PDRS; and

(3) revise, if necessary, the diminished future earning capacity adjustment to reflect consideration of an employee's diminished future earning capacity for injuries based on the data collected. If the Administrative Director determines that there is not a sufficient amount of data to perform a statistically valid evaluation, the Administrative Director shall continue to collect data until a valid statistical sample is obtained. If there is a statistically valid sample of data that the Administrative Director determines supports a revision to the diminished future earning capacity adjustment, the Administrative Director shall revise the PDRS before the mandatory five year statutory revision contained in Labor Code section 4660(c).
