in effect

Cal. Labor Code - LAB § 5400. Section 5400.

Except as provided by sections 5402 and 5403, no claim to recover compensation under this division shall be maintained unless within thirty days after the occurrence of the injury which is claimed to have caused the disability or death, there is served upon the employer notice in writing, signed by the person injured or someone in his behalf, or in case of the death of the person injured, by a dependent or someone in the dependent’s behalf.

Cal. Labor Code - LAB § 5401. Section 5401.

(a) Within one working day of receiving notice or knowledge of injury under Section 5400 or 5402, which injury results in lost time beyond the employee’s work shift at the time of injury or which results in medical treatment beyond first aid, the employer shall provide, personally or by first-class mail, a claim form and a notice of potential eligibility for benefits under this division to the injured employee, or in the case of death, to his or her dependents. As used in this subdivision, “first aid” means any one-time treatment, and any followup visit for the purpose of observation of minor scratches, cuts, burns, splinters, or other minor industrial injury, which do not ordinarily require medical care. This one-time treatment, and followup visit for the purpose of observation, is considered first aid even though provided by a physician or registered professional personnel. “Minor industrial injury” shall not include serious exposure to a hazardous substance as defined in subdivision (i) of Section 6302. The claim form shall request the injured employee’s name and address, social security number, the time and address where the injury occurred, and the nature of and part of the body affected by the injury. Claim forms shall be available at district offices of the Employment Development Department and the division. Claim forms may be made available to the employee from any other source. (b) Insofar as practicable, the notice of potential eligibility for benefits required by this section and the claim form shall be a single document and shall instruct the injured employee to fully read the notice of potential eligibility. The form and content of the notice and claim form shall be prescribed by the administrative director after consultation with the Commission on Health and Safety and Workers’ Compensation. The notice shall be easily understandable and available in both English and Spanish. The content shall include, but not be limited to, the following: (1) The procedure to be used to commence proceedings for the collection of compensation for the purposes of this chapter. (2) A description of the different types of workers’ compensation benefits. (3) What happens to the claim form after it is filed. (4) From whom the employee can obtain medical care for the injury. (5) The role and function of the primary treating physician. (6) The rights of an employee to select and change the treating physician pursuant to subdivision (e) of Section 3550 and Section 4600. (7) How to get medical care while the claim is pending. (8) The protections against discrimination provided pursuant to Section 132a. (9) The following written statements: (A) You have a right to disagree with decisions affecting your claim. (B) To obtain important information about the workers’ compensation claims process and your rights and obligations, go to [applicable Internet Web site(s)], or contact an information and assistance (I&A) officer of the state Division of Workers’ Compensation. You can also hear recorded information and a list of local I&A offices by calling [applicable information and assistance telephone number(s)]. (C) You can consult an attorney. Most attorneys offer one free consultation. If you decide to hire an attorney, his or her fee will be taken out of some of your benefits. For names of workers’ compensation attorneys, call the State Bar of California at [telephone number of the State Bar of California’s legal specialization program, or its equivalent]. (c) The completed claim form shall be filed with the employer by the injured employee, or, in the case of death, by a dependent of the injured employee, or by an agent of the employee or dependent. Except as provided in subdivision (d), a claim form is deemed filed when it is personally delivered to the employer or received by the employer by first-class or certified mail. A dated copy of the completed form shall be provided by the employer to the employer’s insurer and to the employee, dependent, or agent who filed the claim form. (d) The claim form shall be filed with the employer prior to the injured employee’s entitlement to late payment supplements under subdivision (d) of Section 4650, or prior to the injured employee’s request for a medical evaluation under Section 4060, 4061, or 4062. Filing of the claim form with the employer shall toll, for injuries occurring on or after January 1, 1994, the time limitations set forth in Sections 5405 and 5406 until the claim is denied by the employer or the injury becomes presumptively compensable pursuant to Section 5402. For purposes of this subdivision, a claim form is deemed filed when it is personally delivered to the employer or mailed to the employer by first-class or certified mail.

Cal. Labor Code - LAB § 5401.7. Section 5401.7.

The claim form shall contain, prominently stated, the following statement: “Any person who makes or causes to be made any knowingly false or fraudulent material statement or material representation for the purpose of obtaining or denying workers’ compensation benefits or payments is guilty of a felony.” The statements required to be printed or displayed pursuant to Section 1871.2 of the Insurance Code may, but are not required to, appear on the claim form.

Cal. Labor Code - LAB § 5402. Section 5402.

(a) Knowledge of an injury, obtained from any source, on the part of an employer, the employer’s managing agent, superintendent, foreman, or other person in authority, or knowledge of the assertion of a claim of injury sufficient to afford opportunity to the employer to make an investigation into the facts, is equivalent to service under Section 5400. (b) (1) If liability is not rejected within 90 days after the date the claim form is filed under Section 5401, the injury shall be presumed compensable under this division. The presumption of this subdivision is rebuttable only by evidence discovered subsequent to the 90-day period. (2) Notwithstanding paragraph (1), for injuries or illnesses defined in Sections 3212 to 3212.85, inclusive, and Sections 3212.9 to 3213.2, inclusive, if the liability is not rejected within 75 days after the date the claim form is filed pursuant to Section 5401, the injury shall be presumed compensable under this division. The presumption of this subdivision is rebuttable only by evidence discovered subsequent to the 75-day period. (c) Within one working day after an employee files a claim form under Section 5401, the employer shall authorize the provision of all treatment, consistent with Section 5307.27, for the alleged injury and shall continue to provide the treatment until the date that liability for the claim is accepted or rejected. Until the date the claim is accepted or rejected, liability for medical treatment shall be limited to ten thousand dollars ($10,000). (d) Treatment provided under subdivision (c) does not give rise to a presumption of liability on the part of the employer. (e) Upon appropriation by the Legislature, the Division of Workers’ Compensation shall identify and amend its existing data collection processes to include collection of the date on which the claimant is notified of acceptance, denial, or conditional denial of liability for a claim, consistent with this section.

Cal. Labor Code - LAB § 5403. Section 5403.

The failure to give notice under section 5400, or any defect or inaccuracy in a notice is not a bar to recovery under this division if it is found as a fact in the proceedings for the collection of the claim that the employer was not in fact misled or prejudiced by such failure.

Cal. Labor Code - LAB § 5404. Section 5404.

Unless compensation is paid within the time limited in this chapter for the institution of proceedings for its collection, the right to institute such proceedings is barred. The timely filing of an application with the appeals board by any party in interest for any part of the compensation defined by Section 3207 renders this chapter inoperative as to all further claims by such party against the defendants therein named for compensation arising from that injury, and the right to present such further claims is governed by Sections 5803 to 5805, inclusive.

Cal. Labor Code - LAB § 5404.5. Section 5404.5.

(a) Where a claim form has been filed prior to January 1, 1994, and where the claim is denied by the employer, the claim may be dismissed if there has been no activity for the previous 180 days and if the claims adjuster has served notice pursuant to Article 3 (commencing with Section 415.10) of Chapter 4 of Title 5 of the Code of Civil Procedure. The notice shall specify that the claim will be dismissed by operation of law unless an application for adjudication of the claim is filed within 180 days of service of the notice. (b) Where a claim form has been filed prior to January 1, 1994, and where benefits have been furnished by the employer, the claim may be dismissed if there has been no activity for the previous 180 days and if the claims adjuster has served notice pursuant to Article 3 (commencing with Section 415.10) of Chapter 4 of Title 5 of the Code of Civil Procedure. The notice shall specify that the claim will be dismissed by operation of law unless an application for adjudication of the claim is filed within five years of the date of injury or within one year of the last furnishing of benefits, whichever is later. (c) The administrative director may adopt rules of practice and procedure consistent with this section. (d) The provisions of subdivisions (a) and (b) do not limit the jurisdiction of the appeals board. (e) This section is applicable to injuries occurring before January 1, 1994.

The period within which may be commenced proceedings for the reduction of compensation on the ground of serious and willful misconduct of the employee, under provisions of Section 4551, is as follows: Twelve months from the date of injury.

Cal. Labor Code - LAB § 5408. Section 5408.

If an injured employee or, in the case of the employee’s death, any of the employee’s dependents, is under 18 years of age or incompetent at any time when any right or privilege accrues to such employee or dependent under this division, a guardian or conservator of the estate appointed by the court, or a guardian ad litem or trustee appointed by the appeals board, may, on behalf of the employee or dependent, claim and exercise any right or privilege with the same force and effect as if no disability existed. No limitation of time provided by this division shall run against any person under 18 years of age or any incompetent unless and until a guardian or conservator of the estate or trustee is appointed. The appeals board may determine the fact of the minority or incompetency of any injured employee and may appoint a trustee to receive and disburse compensation payments for the benefit of such minor or incompetent and his family.

Cal. Labor Code - LAB § 5409. Section 5409.

The running of the period of limitations prescribed by this chapter is an affirmative defense and operates to bar the remedy and not to extinguish the right of the employee. Such defense may be waived. Failure to present such defense prior to the submission of the cause for decision is a sufficient waiver.

Cal. Labor Code - LAB § 5410. Section 5410.

Nothing in this chapter shall bar the right of any injured worker to institute proceedings for the collection of compensation within five years after the date of the injury upon the ground that the original injury has caused new and further disability. The jurisdiction of the appeals board in these cases shall be a continuing jurisdiction within this period. This section does not extend the limitation provided in Section 5407.

Cal. Labor Code - LAB § 5410.1. Section 5410.1.

Should any party to a proceeding institute proceedings to reduce the amount of permanent disability awarded to an applicant by the appeals board and be unsuccessful in such proceeding, the board may make a finding as to the amount of a reasonable attorney’s fee incurred by the applicant in resisting such proceeding to reduce permanent disability benefits previously awarded by the appeals board and assess the same as costs upon the party instituting the proceeding for the reduction of permanent disability benefits.

Cal. Labor Code - LAB § 5411. Section 5411.

The date of injury, except in cases of occupational disease or cumulative injury, is that date during the employment on which occurred the alleged incident or exposure, for the consequences of which compensation is claimed.

Cal. Labor Code - LAB § 5412. Section 5412.

The date of injury in cases of occupational diseases or cumulative injuries is that date upon which the employee first suffered disability therefrom and either knew, or in the exercise of reasonable diligence should have known, that such disability was caused by his present or prior employment.

Cal. Labor Code - LAB § 5413. Section 5413.

A determination of facts by the appeals board under this chapter has no collateral estoppel effect on a subsequent criminal prosecution and does not preclude litigation of those same facts in the criminal proceeding.
