Burn Injuries

Two statutes make a burn case different from almost every other work injury in California.

Labor Code § 4656(c)(3)(D) — severe burns get 240 compensable weeks of temporary disability instead of 104. That is 136 extra weeks, worth up to $239,918.96 at the 2026 maximum rate.

Labor Code § 4660.1(c)(2)(B) — "severe burn" is one of four examples the Legislature named of a catastrophic injury, in a list the statute expressly opens with "including, but not limited to", which lifts the ordinary bar on adding psychiatric impairment to the rating.

Neither is applied automatically. Both have to be raised.

The 240-week benefit

For most California workers, temporary disability stops at 104 compensable weeks. Section 4656(c)(3) lists nine conditions that get 240 weeks within five years of the date of injury instead, and severe burns is one of them.

The statute does not define "severe." It says "severe burns" and nothing more. Expect the carrier to read that narrowly, and expect the argument to be about depth, total body surface area, location, grafting, and functional outcome.

Our position is that Labor Code § 3202 resolves the ambiguity, requiring the workers' compensation statutes to be "liberally construed by the courts with the purpose of extending their benefits for the protection of persons injured in the course of their employment." A full-thickness burn requiring grafting is severe on any reading. A deep partial-thickness burn to the hands or face, with contracture and permanent scarring, should be.

The practical problem is not the argument. It is that nobody makes it. The 104-week cutoff is generated by the claims system on a schedule. If nothing in the file flags § 4656(c)(3), the benefit stops and the worker is told that is the law.

If you have a significant burn and your temporary disability ended at two years, check this first. It is worth more than anything else on this page.

How burns are rated

Burns are rated under the skin chapter of the AMA Guides, and the method is unlike the orthopedic chapters. There is no goniometer and no table of diagnoses. The rating is driven by the effect on activities of daily living.

The chapter evaluates signs, symptoms, impact on activities of daily living, the burden of ongoing treatment, and confinement.

One point that gets misapplied constantly: a Class 1 rating does not require an underlying activities-of-daily-living impact in order to exceed 0%. Evaluators who treat "no ADL loss" as automatically meaning "zero percent" are reading the chapter wrong.

And the ADL history is the entire case. Unlike a shoulder, where the measurement produces the number, a burn rating is produced by what the worker reports about daily function — sun sensitivity, temperature intolerance, itching, sleep disruption, inability to wear ordinary clothing, restriction on being outdoors, the time consumed by daily skin care. An evaluation that does not take that history in detail cannot produce an accurate class.

What combines with the skin rating

Skin impairment is "rated separately and combined with other body system ratings using the Combined Values Chart." In a serious burn case that matters enormously, because burns rarely produce only skin damage:

Joint contracture across a burn scar — rated as loss of motion in the affected extremity chapter, combined with the skin rating.

Peripheral nerve damage in the burned area.

Inhalation injury — reactive airway disease, chronic bronchitis, or pulmonary fibrosis after smoke or chemical inhalation, rated under the respiratory chapter. Note that both "pulmonary fibrosis" and "chronic lung disease" are separately on the § 4656(c)(3) list, so an inhalation component may independently support the 240-week benefit.

Amputation — also on the § 4656(c)(3) list.

Complex regional pain syndrome, which is well documented after burn injury. How CRPS is rated.

And the psychiatric consequence, which in a burn case is not incidental.

Disfigurement

This is the part of a burn case the rating system handles worst, and it deserves a straight answer.

The Guides acknowledge that disfigurement "usually has no effect on body function" but may affect activities of daily living where it causes "social rejection or an unfavorable self-image with self-imposed isolation."

That is the entire hook, and it is narrow. A worker with visible facial or hand scarring, whose body function is intact, is rated on whether the disfigurement has produced measurable functional and social consequences — not on the disfigurement itself.

Which means the documentation has to be specific. Not "the applicant is self-conscious." Specifics: withdrawal from activities previously engaged in, avoidance of public settings, changes to clothing, the reactions the worker actually encounters, and — where it exists — treatment for the resulting psychological consequences.

And this is where the third-party case becomes essential.

Workers' compensation pays nothing for disfigurement as such. A civil claim does. In a burn case with permanent visible scarring, the disfigurement component of a civil recovery is frequently larger than the entire workers' compensation claim.

Psychiatric injury after a burn

For injuries on or after January 1, 2013, § 4660.1(c)(1) bars increasing the rating for "sleep dysfunction, sexual dysfunction, or psychiatric disorder" arising out of a compensable physical injury.

Section 4660.1(c)(2)(B) excepts catastrophic injury, "including, but not limited to, loss of a limb, paralysis, severe burn, or severe head injury."

Severe burn is on the Legislature's own list. Where the burn is severe, the exception applies on the face of the statute — no Wilson factor analysis required.

Where the burn is not "severe," the Wilson factors are the route, and they favor burn cases: intensity of treatment, ultimate outcome at permanent and stationary, severity and impact on activities of daily living, and closeness of analogy to the named injuries. A burn that required grafting, multiple debridements, and months of wound care satisfies the first factor on its own.

And post-traumatic stress after a fire or explosion may qualify independently under § 4660.1(c)(2)(A) — direct exposure to a significant violent act — depending on the mechanism.

How these happen, and who else may be liable

Thermal. Restaurant and commercial kitchen work — fryers, steam, grease fires, hot oil transfer. Roofing and paving — hot asphalt and kettles. Welding and hot work. Foundry and forge. Utility and line work.

Electrical. Arc flash in switchgear, panel, and transformer work. Arc flash burns are a category of their own because they combine thermal burn, blast injury, hearing damage, and frequently brain injury from the concussive event.

Chemical. Industrial cleaning, plating, semiconductor, refinery. Hydrofluoric acid burns in particular behave differently from other chemical burns and are frequently under-treated initially.

Scald and steam. Hospitality, laundry, food processing, boiler rooms.

Third-party exposure in burn cases is high. Recurring defendants: equipment manufacturers where a pressure relief, interlock, or thermal cutoff failed; chemical manufacturers and distributors on labeling and warning; utilities; general contractors and property owners; and maintenance contractors on lockout/tagout failures.
