Back injuries are the #1 workers’ comp claim in California — and among the most undervalued.
By Eman Yazdchi, Esq. · Certified Specialist in Workers' Compensation Law
Back injuries account for more workers' compensation claims in Palmdale than any other body part — and it's not hard to see why. Aerospace assemblers at Plant 42 spend hours hunched over workbenches performing precision tasks. Amazon fulfillment workers on Rancho Vista lift, bend, and twist through 10-hour shifts. Construction laborers along the 14 corridor haul materials up ladders and across uneven ground. Healthcare workers at Palmdale Regional Medical Center transfer patients who outweigh them. Every one of these jobs attacks the spine in different ways, and every one produces back injuries that insurers aggressively dispute.
The challenge with back injury claims isn't proving you're in pain — it's proving the extent of your permanent disability and fighting the insurer's attempts to reduce your rating through apportionment. A herniated disc at L5-S1 may sound straightforward, but the difference between a 20% disability rating and a 45% rating can mean over $100,000 in additional compensation. That difference depends on medical evidence, the rating methodology used, and how effectively your attorney fights apportionment — the insurer's attempt to blame your back condition on age, genetics, or prior injuries.
As Palmdale's hometown board-certified workers' comp specialist, we handle more back injury claims from AV workers than any other injury type. We know which medical evaluators provide thorough, evidence-based ratings. We know how to counter the apportionment arguments that Palmdale insurers rely on. And we fight for the maximum disability rating your condition justifies.
California uses the AMA Guides to the Evaluation of Permanent Impairment, 5th Edition to rate permanent disability from back injuries. The rating process is complex and directly determines your compensation. Here's what Palmdale workers need to understand:
The AMA Guides 5th Edition provides two methods for rating spinal impairment. The Diagnosis-Related Estimates (DRE) method is the preferred approach, categorizing injuries into five levels based on clinical findings like radiculopathy, loss of motion, and surgical history. The Range of Motion (ROM) method measures actual spinal flexibility and is used when DRE doesn't adequately capture your impairment — typically for multi-level injuries. Insurers often push for the method that produces the lower rating. We advocate for the method that accurately reflects your disability.
Apportionment under LC §4663 is the insurer's primary weapon against back injury claims. They'll argue that some percentage of your disability is due to age-related degeneration, prior injuries, or genetic predisposition — not your work at Plant 42 or on a construction site. For example, an insurer might agree you have 40% permanent disability but argue that 50% of it is "non-industrial," reducing your compensable rating to just 20%.
We challenge unfair apportionment through medical evidence showing that your work activities were the primary cause of your current condition, that degenerative changes were asymptomatic before the work injury, and that the apportionment opinion lacks the substantial medical evidence required under Escobedo v. Marshalls. This is technical litigation that requires a specialist — not a generalist.
If your treating physician recommends spinal surgery — a discectomy, laminectomy, or fusion — the insurer must authorize it through Utilization Review (UR) based on the Medical Treatment Utilization Schedule (MTUS). If UR denies the surgery, we appeal through Independent Medical Review (IMR) under LC §4610. IMR is decided by independent physicians, and we've successfully obtained surgical authorization for numerous Palmdale workers whose procedures were initially denied.

Tap to call →Palmdale back injury claims are heard at the Van Nuys WCAB. Apportionment disputes and PD rating challenges are litigated here, often requiring expert medical testimony.
Palmdale Regional Medical Center and Kaiser Permanente Palmdale provide orthopedic and spine care. For complex spinal surgery, AV workers are often referred to spine centers in the greater LA area. We ensure your treating physician is within the MPN and provides thorough documentation.
Back injury PD ratings typically range from 10% (mild strain) to 60%+ (multi-level fusion with complications). A 30% rating for a 45-year-old construction worker can be worth over $50,000 in PD benefits alone — before settlement negotiations increase the value further.
