WCAB Reduces Disability Rating but Allows Kite Addition in Blake

A July 2026 WCAB panel decision illustrates how several technical rating doctrines can change a permanent-disability award.

Read the official WCAB panel decision.

A DMV Examiner’s Injury and a 72 Percent Award

Jeffrey Blake sustained industrial injury to his neck, psyche, head, and in the form of headaches. The WCJ found 72 percent permanent disability, no apportionment, a separate headache pain add-on, and addition rather than combination of orthopedic and psychiatric impairments.

The State challenged each component. The Appeals Board agreed in part and reduced the compensable rating to 47 percent.

Section 4663 Apportionment Had to Be Applied

The orthopedic evaluator attributed 40 percent of the cervical disability to factors predating the current injury. He explained the preexisting degeneration and prior symptoms, and how the new injury aggravated that condition. The Board found the analysis sufficiently reasoned and incorporated the apportionment.

A Second Chapter 18 Pain Add-On Was Duplicative

The neurologist assigned a three-percent pain add-on for headaches even though the cervical rating already included a Chapter 18 pain increase. The Schedule permits a maximum three-percent pain addition from a single injury, and Blackledge requires underlying ratable impairment for an add-on.

Because the headache rating consisted only of the additional pain percentage and appeared to arise from the same cervical mechanism, the Board excluded it.

Why Psychiatric and Orthopedic Impairments Were Added

The Board nevertheless affirmed addition of the psychiatric and cervical impairments under Kite and the en banc decision in Vigil. The psychiatric evaluator explained a synergistic cycle: psychiatric symptoms worsened pain, and pain worsened psychiatric symptoms. That medical explanation supported addition rather than use of the Combined Values Chart.

Practical Rating Lessons

Blake shows that apportionment, pain, and impairment-combination questions must be analyzed separately. A physician must explain causation of disability for section 4663, avoid duplicative Chapter 18 additions, and provide a concrete medical explanation when asserting that two impairments amplify one another.

The decision is fact-specific panel authority, but it offers a useful checklist for evaluating a permanent-disability report before trial.
