ENVIROSERVE); and STATE COMPENSATION INSURANCE FUND, Defendant(s).Case No. ADJ1078163 (BAK 0145426) OPINION AND DECISION AFTER RECONSIDERATION(EN BANC) JOYCE GUZMAN, Applicant, vs.MILPITAS UNIFIED SCHOOL DISTRICT, Permissibly Self-Insured; and KEENAN and ASSOCIATES, Adjusting Agent, Defendant(s).Case No. ADJ3341185 (SJO 0254688)OPINION AND DECISION AFTER RECONSIDERATION(EN BANC) The Appeals Board granted reconsideration in each of these matters. Because these cases present common issues of law, and for judicial efficiency, they have been consolidated for the limited purpose of issuing a joint Opinion and Decision After Reconsideration. (Cal. Code Regs., tit. 8, § 10589.) Because of the important legal issue as to whether and how the AMA Guides [1]portion of the 2005 Schedule for Rating Permanent Disabilities (2005 Schedule or Schedule)[2] may be rebutted, and to secure uniformity of decision in the future, the Chairman of the Appeals Board, upon a majority vote of its members, assigned these cases to the Appeals Board as a whole for an en banc decision. (Lab. Code, § 115.)[3] For the reasons below, we hold in summary that: (1) the AMA Guides portion of the 2005 Schedule is rebuttable; (2) the AMA Guides portion of the 2005 Schedule is rebutted by showing that an impairment rating based on the AMA Guides would result in a permanent disability award that would be inequitable, disproportionate, and not a fair and accurate measure of the employee's permanent disability; and (3) when an impairment rating based on the AMA Guides has been rebutted, the WCAB may make an impairment determination that considers medical opinions that are not based or are only partially based on the AMA Guides. In the cases before us, however, we explicitly emphasize that we are not determining whether the standards for rebutting the AMA Guides portion of the 2005 Schedule have been or may be met. Instead, in each case, we are remanding to the assigned workers' compensation administrative law judge (WCJ) to decide these questions in the first instance. Further, we expressly proclaim that our holding does not open the door to impairment ratings directly or indirectly based upon any Schedule in effect prior to 2005, regardless of how "fair" such a rating might seem to a physician, litigant, or trier-of-fact. I. BACKGROUND A. The Almaraz Case Applicant, Mario Almaraz, sustained an admitted industrial injury to his back on November 5, 2004, while employed as a truck driver by Environmental Recovery Services (a.k.a. Enviroserve), insured by defendant, State Compensation Insurance Fund. Applicant did not testify at trial, but the medical evidence indicates he injured himself when, while manually pulling a large tarp on to the top of the trailer of his truck, he felt a pop in his low back. He experienced low back pain extending into his right leg. On December 29, 2004, applicant had a laminectomy and discectomy at L4-5. After a period of temporary disability, applicant began working as an instructor at a truck driving school. The parties stipulated that, following his injury, applicant's employer did not offer him modified work as a truck driver. Applicant was evaluated by Bruce E. Fishman, M.D., as an agreed medical evaluator (AME). In his initial report dated November 22, 2006, Dr. Fishman declared applicant to be permanent and stationary. He concluded that applicant has 12% whole person impairment (WPI) under the AMA Guides, based on a DRE lumbar category III. He also noted, however, that applicant is permanently limited to light duty work and permanently precluded from prolonged sitting activities. Dr. Fishman found that 20% of applicant's current lumbosacral disability was non-industrial - i.e., it was caused by the natural progression of prior non-occupational injuries, by his diffuse underlying degenerative lumbar disc disease, and by pre-existing spondylosis. Dr. Fishman stated that he had no job analysis for applicant, but reported that applicant had described his job as involving: (1) lifting up to 100 pounds; (2) pushing and pulling drums weighing up to 1500 pounds; (3) bending, stooping, twisting, climbing, squatting, kneeling, and reaching overhead; (4) using a pallet jack, a forklift, and dollies; and (5) working 8 to 12 hour shifts, with 80% of the time spent sitting and the remaining 20% spent standing or walking. In the absence of a formal job analysis, Dr. Fishman indicated he could not determine whether applicant could return to his job duty as a truck driver. Nevertheless, Dr. Fishman stated that applicant "clearly would be unable" to move 1500 pound drums. Dr. Fishman issued a supplemental AME report dated October 16, 2007. In that report, he reiterated that applicant is limited to light duty work and is precluded from prolonged sitting. He stated that these restrictions are both actual and prophylactic. Applicant's claim went to trial, primarily on the issues of permanent disability and apportionment. Applicant argued that the WCAB has the discretion to award permanent disability based on his work restrictions, instead of by multiplying his AMA Guides impairment by the appropriate diminished future earning capacity (DFEC) adjustment factor per the 2005 Schedule. The parties stipulated that, before apportionment, applicant's injury would rate 17% under the 2005 Schedule and 58% under the 1997 Schedule. On April 23, 2008, WCJ found that applicant's November 4, 2004 back injury caused 14% permanent disability, after apportionment. In making this permanent disability determination, the WCJ utilized the rating methodology established by the 2005 Schedule, including its provision that the extent of an injured employee's permanent impairment is determined by use of the AMA Guides. The WCJ concluded he was not free to make a permanent disability finding based on the work preclusions set forth by Dr. Fishman. The WCJ said that, in enacting Labor Code section 4660,[4]the Legislature "mandated the use of the AMA Guide[s]." Specifically, he cited to section 4660(b)(1), which provides: "For purposes of this section, the 'nature of the physical injury or disfigurement' shall incorporate the descriptions and measurements of physical impairments and the corresponding percentages of impairments published in the [AMA Guides]." The WCJ further stated, "it is within the purview of the Legislature to establish the system for rating permanent disability." Because "the Legislature has established what that system is," the WCAB "is not at liberty to deviate from th[ose] criteria." Accordingly, pursuant to the parties' stipulation to 17% permanent disability under the 2005 Schedule, before apportionment, the WCJ found that applicant's permanent disability is 14% - after apportionment of 20% of his disability to non-industrial causation. Applicant filed a timely petition for reconsideration, contending in substance that: (1) section 4660 merely requires that "account shall be taken" of the AMA Guides; therefore, the Guides is not conclusive and unrebuttable; (2) the AMA Guides need not be blindly followed where the Guides does not completely and fairly describe and measure the injured employee's impairment; and (3) where the AMA Guides does not fairly and accurately reflect the injured employee's impairment, other measures of disability should be used. No answer to the petition was received. On July 7, 2008, we granted reconsideration. B. The Guzman Case Applicant, Joyce Guzman, sustained an admitted industrial injury to her bilateral upper extremities during a cumulative period ending on April 11, 2005, while employed as a secretary by defendant, the Milpitas Unified School District (adjusted by Keenan and Associates). Applicant was evaluated by Steven D. Feinberg, M.D., as an AME. In his initial report, Dr. Feinberg diagnosed bilateral carpal tunnel syndrome, which was not yet permanent and stationary. In his December 2, 2005 report, Dr. Feinberg declared applicant to be permanent and stationary. He opined that applicant's bilateral upper extremity injury caused "a 25% loss of her . preinjury capacity for pushing, pulling, grasping, gripping, keyboarding [and] fine manipulation." He further stated that applicant "could not go back to [her] former occupation," because it would "caus[e] a gradual worsening of her condition." On July 13, 2007, Dr. Feinberg issued a supplemental AME report that analyzed applicant's permanent disability utilizing the AMA Guides. He concluded that applicant's injury caused 3% whole person impairment for each upper extremity, based upon applicant's symptoms and her reported functional difficulties secondary to her symptoms. In a March 21, 2008 report, Dr. Feinberg reiterated that applicant's bilateral upper extremity injury caused WPI under the AMA Guides of 3% for each side and also that her injury caused a 25% loss of her pre-injury capacity for pushing, pulling, grasping, gripping, keyboarding and fine manipulation. In his final report of April 30, 2008, however, Dr. Feinberg stated that applicant's bilateral upper extremity injury precludes her from "very forceful, prolonged repetitive and forceful repetitive work activities." He further stated:
