In California, Labor Code §5814 imposes a 25% penalty on workers' compensation benefits unreasonably delayed or denied, applied to the specific benefit withheld. The penalty is awarded by the WCAB judge on top of the underlying compensation. Yazdchi Law, a Certified Specialist in Workers' Compensation Law firm, handles §5814 penalty claims statewide.

Under California Labor Code §5814, a California workers' compensation insurer or self-insured employer that unreasonably delays or denies a benefit faces a 25% penalty on the specific benefit unreasonably withheld. The penalty applies to the actual species at issue — temporary disability unpaid on time, permanent disability withheld, or treatment authorization unreasonably denied — not the entire award. The penalty is awarded by the WCAB judge on the record, in addition to the underlying benefit and the self-imposed increase under California Labor Code §4650.
Under California Labor Code §5814, an unreasonable delay or denial is one without genuine factual or legal dispute. California case law has applied §5814 to: temporary disability checks issued late without explanation; treatment authorizations sitting past the §4610 UR timeframes; medical mileage reimbursements paid months late; permanent disability indemnity withheld after Stipulations with Request for Award; and Compromise & Release proceeds delayed beyond the statutory payment window. A genuine legal dispute — for example, a UR denial later overturned through IMR — is generally not unreasonable absent additional conduct.
Under California Labor Code §5814, the California 25% penalty is calculated on the specific species of benefit unreasonably delayed. If $10,000 in temporary disability was withheld for three months without justification, the §5814 penalty is $2,500. The penalty is separate from the California Labor Code §4650 10% self-imposed increase for late indemnity payments, separate from any back interest owed, and separate from any §132a remedies if the underlying delay was retaliatory.
Under California Labor Code §4610, UR decisions on California medical treatment must be made within strict time limits — five working days for prospective review, 72 hours for expedited review, 30 days for retrospective review. An untimely UR decision is procedurally invalid and the requested treatment is deemed authorized. A pattern of untimely UR or boilerplate denials later overturned through IMR under California Labor Code §4610.5 can support a §5814 California penalty for unreasonable denial of treatment.
Under California Labor Code §5814 and California Labor Code §5410, a California injured worker generally has the five-year reopening window to claim a penalty for benefits unreasonably delayed during the pendency of the case. The penalty is asserted in a Petition for Penalty filed with the WCAB. Each instance of unreasonable delay can be the subject of its own §5814 penalty claim, and multiple penalty claims can be heard together at a single California hearing.
