A Brain Injury Is Not a Mental Illness

Federal Court Rules in Favor of Chevron Worker With TBI

Dorian Law is proud to announce a significant victory for our client in his fight for long-term disability benefits against Chevron Corporation and its claims administrator, ReedGroup. On October 1, 2025, the U.S. District Court for the Northern District of California entered judgment in Mr. Cobb's favor.

Two Decisive Victories

01

De Novo Standard of Review

We stripped ReedGroup of the deferential standard it counted on — forcing the court to evaluate the evidence fresh, without any presumption in the insurer's favor.

02

TBI Is a Physical Injury

We defeated the administrator's attempt to reclassify Mr. Cobb's traumatic brain injury as a "mental illness" — a tactic designed to exploit a 24-month limitation and permanently cut off his benefits.

"My Insurer Says My Physical Injury Is a Mental Health Issue. What Can I Do?"

Your doctor says you can't work. You've paid your disability insurance premiums for years. Yet, a letter arrives from a claims administrator you've never met, filled with confusing jargon, telling you your benefits are terminated.

For our client, a dedicated Chevron plant operator, that was his reality. In 2017, while on approved short-term disability for work-related stress, Mr. Cobb was in a catastrophic motorcycle accident that was not his fault. He suffered a severe traumatic brain injury, a subarachnoid hemorrhage, and was in a coma for ten days.

Chevron's plan administrator, ReedGroup, approved his long-term disability claim and paid his benefits for over 24 months. Then they abruptly terminated them.

Their reason? They claimed Mr. Cobb's disability was not his TBI, but rather a mental/behavioral health condition. Because Chevron's plan limits mental illness benefits to 24 months, ReedGroup argued he had exhausted his entitlement.

They took a clear, physical, life-altering brain injury — documented by MRIs, PET scans, and a treating team of neurologists and specialists — and called it a mental illness, perhaps to save money. This tactic is not an isolated error. It is a strategy that some insurers use to cap financial liability by reclassifying long-term physical injuries as mental health conditions subject to policy limitations. This is the story of how Dorian Law dismantled it.

Battle One

Winning the Standard of Review

Before we could argue the facts of the TBI, we had to win a critical procedural fight. The standard of review is often described as the single most important factor in ERISA cases — it determines how much benefit of the doubt the court gives the insurer going in.

What Chevron Wanted

"Abuse of Discretion" Review

A deferential standard that heavily favors the insurer. The court can only ask whether the administrator's decision was "reasonable" — even if it was wrong. Insurers almost always win under this standard.

What We Fought For

"De Novo" Review

A fair standard meaning "from the beginning." It empowers the judge to review all evidence with fresh eyes, and decide independently if the administrator's stated reason for denial was right.

We didn't accept the plan's language at face value. We argued that while the Chevron Plan allowed delegation of discretion to ReedGroup, it required that delegation to be made in a specific written instrument — a document Chevron never produced. Their attempt to rely on the employee-facing Summary Plan Description (SPD) as that instrument failed: an SPD does not meet the Plan's own legal requirements for such a delegation.

The Court agreed. Chevron had failed to prove it ever properly delegated discretionary authority to ReedGroup. The deferential standard was off the table. Mr. Cobb would get the fair, fresh de novo review he deserved.

Battle Two

Proving TBI Is a Physical, Neurological Injury

With a level playing field secured, we attacked the merits directly. Chevron's case rested on cherry-picked evidence: a neuropsychological exam using the dismissive phrase "generally intact," and a file-reviewing physician — Dr. Farache, who was not a TBI specialist — claiming the disability was purely psychological.

We responded with a comprehensive body of objective medical evidence on four fronts.

Objective Imaging

MRI & PET Scan Findings

MRI scans revealed permanent microhemorrhagic damage — the signature of Diffuse Axonal Injury, a physical tearing of the brain's connective wiring. PET scans showed measurably diminished frontal lobe metabolism: objective proof that the front of Mr. Cobb's brain was not functioning correctly.

"Multiple punctate chronic microhemorrhagic residua" & "diminished frontal lobe metabolism"

Objective Testing

Vestibular (VNG/vHIT) Results

Specialized vestibular testing showed central pathology — proving that Mr. Cobb's severe, debilitating dizziness had a physical, brainstem origin. It was not subjective. It was not psychological.

Expert Medical Opinions

The Treating Team's Consensus

Mr. Cobb's entire treating team supported him. Neurologist Dr. Neff diagnosed disability from the "sequelae of traumatic brain injury." Most powerfully, his treating psychiatrist, Dr. Tran, stated in writing that the primary cause of his disability "is not psychological."

Procedural Failure

The Missing Vocational Analysis

To deny benefits past 24 months, ReedGroup had to prove Mr. Cobb could perform any gainful occupation meeting the plan's income threshold. They never ran a vocational analysis, never identified a single job, and never calculated whether any such role would meet the plan's 70% wage requirement.

No vocational analysis. No identified occupation. No wage calculation.

The Outcome

Judgment Entered in Favor of Daniel Cobb

Faced with the objective medical evidence and the procedural failures we identified, the Court entered judgment in Mr. Cobb's favor and remanded the case to the administrator for further proceedings. Insurers will continue to use mental illness limitations to deny claims for TBI, Post-Concussive Syndrome, Chronic Fatigue Syndrome, and Long COVID. This case proves those tactics can be defeated.

Your Questions Answered

Can my disability insurer deny my TBI claim because I have a history of depression or anxiety? +

No. A prior or co-existing mental health condition does not give an insurer the right to deny a legitimate disability claim based on a new and distinct physical injury like a TBI. In Cobb v. Chevron, we successfully proved that our client's disability was caused by his neurological injury — not his prior history of depression.

What is the most important evidence to prove a TBI disability claim? +

Objective medical evidence is crucial. This includes advanced imaging — MRI and PET scans showing structural or functional brain damage — as well as neuropsychological testing documenting cognitive deficits in memory and processing speed. Specialized vestibular testing (VNG/vHIT) can also objectively prove the brain-based cause of symptoms like dizziness, as it did in Mr. Cobb's case.

Is a "paper review" by the insurance company's doctor enough to terminate my benefits? +

A paper review can be enough for an insurer to terminate benefits — but it shouldn't be, and courts often reject those reviews when they contradict the findings of treating specialists without a sound, medically substantiated basis. In Mr. Cobb's case, we successfully argued that the comprehensive, in-person evaluations by his treating team were far more credible than a file review conducted by a physician who specialized in carpal tunnel syndrome — not traumatic brain injuries.

What does "any occupation" mean in an ERISA disability plan? +

Be cautious of general answers — the definition varies materially from policy to policy. Generally, after an initial period, ERISA plans require you to prove you cannot perform any occupation for which you are reasonably qualified. But the specific requirements differ significantly between plans: income thresholds, excluded occupations, and the role of DSM diagnoses all matter. In Mr. Cobb's case, a key part of our argument was showing that his specific limitations prevented him from (1) performing any job providing the plan's required income level, (2) in an occupation not offered by Chevron itself, and (3) not caused by a psychopathological condition in the DSM-V — three elements specific to Chevron's plan language that ReedGroup never addressed.

How can an ERISA lawyer help if my long-term disability claim was denied? +

An experienced ERISA attorney can manage the entire appeal process, gather the necessary medical and vocational evidence, challenge the insurer's reasoning, and — if necessary — file a federal lawsuit to recover your benefits. As we did in the Cobb case, a skilled lawyer can also identify critical procedural errors that change the standard of review — and that argument alone can determine the outcome of the case before a single medical fact is argued.
