WAI CHIU LI vs. COUNTY OF LOS ANGELES

The Workers' Compensation Appeals Board denied the County of Los Angeles' Petition for Reconsideration. The Board upheld its prior decision to increase applicant Wai Chiu Li's permanent disability rating from 15% to 36% for a left forearm injury. This increase was based on the agreed medical examiner's use of clinical judgment to incorporate grip strength loss, consistent with the AMA Guides. The Board emphasized that physician judgment is crucial in accurately assessing impairment according to the Guides.

STEVEN CASE vs. GOLDEN GATE BRIDGE HIGHWAY AND TRANSPORTATION DISTRICT

The Workers' Compensation Appeals Board granted reconsideration to increase applicant's permanent disability rating for bilateral shoulder injury from 9% to 38%. The Board found the Agreed Medical Evaluator's (AME) alternative rating, based on strength loss, was substantial medical evidence and properly considered within the AMA Guides. The WCJ erred in applying an overly restrictive interpretation of "complex or extraordinary" cases for deviating from strict AMA Guides ratings. The AME's use of strength loss data from the AMA Guides, even for an age outside the specified range, was permissible under the *Almaraz-Guzman* line of cases when justified by clinical judgment.

ROBERT LEON vs. RF DEVELOPMENT & BUSCH CORPORATION, LINCOLN GENERAL INSURANCE

In this workers' compensation case, the defendant sought reconsideration of a $37\%$ permanent disability award, arguing the physician's impairment rating improperly deviated from the AMA Guides. The Appeals Board granted reconsideration, finding the physician's justification for not strictly applying the Guides was insufficient and not based on substantial medical evidence. Specifically, the physician's reliance on subjective complaints and analogies to amputation were not adequately supported. The Board rescinded the award and remanded the case for a new rating strictly following the AMA Guides.

Timothy Bedford vs. CITY OF LOS ANGELES

This Workers' Compensation Appeals Board case denies reconsideration of a permanent disability rating. The Board affirmed the use of Figure 15-19 of the AMA Guides, finding it permissible to use any chapter or method within the Guides that most accurately reflects impairment. The Agreed Medical Evaluator's opinion was deemed substantial, as he explained how Figure 15-19 was used to derive a more accurate rating based on the applicant's specific spinal condition. The decision also distinguished the current case from prior panel decisions regarding the application of the AMA Guides and work limitations.

GREGORY GREENE vs. CENTRAL PARKING SYSTEMS, SEDGWICK CMS

In this workers' compensation case, the Appeals Board denied the defendant's petition for reconsideration. The defendant challenged a $75\%$ permanent disability award, arguing the primary treating physician's rating improperly combined various lower extremity impairments, violating the AMA Guides. The Board found the WCJ's reliance on the physician's opinion was supported by substantial evidence, emphasizing the need for accurate, not mechanical, application of the Guides. A dissenting opinion argued the rating was not substantial evidence as it failed to follow proper *Almaraz-Guzman* procedures for deviating from strict AMA Guides application and advocated for remand.

ARTEMIO GONZALEZ vs. RANGEL DRYWALL, INC., STATE COMPENSATION INSURANCE FUND

The applicant sustained an admitted industrial injury to his left lower extremity, specifically a fractured ankle requiring surgery. The defendant sought reconsideration of the WCJ's award of 30% permanent disability, arguing the panel QME's reports lacked specific measurements and explanations required by the AMA Guides. The Appeals Board affirmed the WCJ's decision, finding the QME's deposition testimony, which provided detailed explanations and measurements, constituted substantial evidence. The Board clarified that while AMA Guides sections must be followed, physicians can use their clinical judgment and specific tables within the Guides as long as the basis is explained.

Stephanie MOTEN vs. CITY OF LOS ANGELES

This case involves a dispute over Stephanie Moten's permanent disability rating following a work injury. Both the applicant and defendant sought reconsideration of an award of 19% permanent disability. The Appeals Board found the Agreed Medical Evaluator's (AME) permanent disability ratings were not substantial evidence due to improper application of the AMA Guides and failure to properly analyze nerve impairment. Consequently, the Board deferred the issues of permanent disability and attorney's fees, returning the case to the trial level for further proceedings.

Mario Almaraz, Joyce Guzman vs. Environmental Recovery Services (a.k.a. ENVIROSERVE), State Compensation Insurance Fund, Milpitas Unified School District, Permissibly Self-Insured, Keenan & Associates, Adjusting Agent

The Appeals Board held that the AMA Guides portion of the 2005 Schedule for Rating Permanent Disabilities is rebuttable by showing that an impairment rating based on the AMA Guides would be inequitable, disproportionate, and not a fair and accurate measure of the employee’s permanent disability.

GRACE AOKI vs. CITY OF TORRANCE

This case concerns a library page's permanent disability rating for a right shoulder injury. The agreed medical evaluator combined ratings for loss of motion and weakness/grip strength, exceeding AMA Guides limitations for combining such impairments. The Appeals Board found the physician's report insufficient to rebut AMA Guide standards or explain the combined rating. Consequently, the permanent disability award was reduced from 46% to 20%.

JOHN VLCEK vs. THE HOME DEPOT, permissibly self-insured

This case involves an admitted industrial knee injury where the applicant disputed the awarded 4% permanent disability. The Appeals Board granted reconsideration to address how diminished future earning capacity (DFEC) and AMA Guides impairments are rebutted under the 2005 Schedule. The Board is returning the case to the trial level to allow the judge and parties to apply recent en banc decisions in *Ogilvie* and *Almaraz*. These decisions clarify the methods for rebutting the DFEC and AMA Guides portions of the permanent disability rating schedule.
