California Form 5021: Doctor's First Report of Injury

Every physician who treats a California worker for an occupational injury or illness files this three-sheet report after the first examination. It records the employer and insurer, how the injury happened, subjective complaints, exam and test findings, up to 12 ICD-10 diagnoses, treatment, the plan and work status. Copies go to the claims administrator, which currently mails a copy to the Department of Industrial Relations.

Who completes it

The treating physician completes the report and signs the declaration; under 8 CCR 9785 that includes the primary treating physician, emergency and urgent care physicians, and each new primary treating physician. Item 17, how the injury happened, is for the patient to complete if able, otherwise the doctor completes it.

How to fill it in

Filing instructions (top of Sheet 1)

The header restates the rule: within 5 days of your initial examination, for every occupational injury or illness, send two copies to the employer's workers' compensation insurance carrier or the insured employer. Failure to file a timely report may result in a civil penalty. For diagnosed or suspected pesticide poisoning, also send a copy to the Department of Industrial Relations and notify the local health officer by telephone within 24 hours.

Items 1 to 16: Insurer, employer, patient and injury details

Enter the insurer, the employer's name and address, and the nature of the employer's business, described specifically. Then the patient's name, sex, date of birth, address, phone number, specific job title and Social Security number; the address, city and county where the injury occurred; the date and hour of injury or onset of illness; the date last worked; the date and hour of the first exam or treatment; and whether your office treated the patient before.

Item 17: Describe how the accident or exposure happened

This portion is for the patient, if able, and asks for the specific object, machinery or chemical involved, using the reverse side if more space is needed. If the patient cannot complete it, the doctor completes it immediately; the form states that a patient's inability or failure to do so does not affect workers' compensation rights. Physicians using computerized systems keep the employee's statement with the medical record.

Items 18 and 19: Subjective Complaints; Objective Findings

Item 18 records the patient's subjective complaints. Item 19 has two parts: A, the physical examination findings, and B, X-ray and laboratory results. For part B the form asks you to state if results are none or pending, so do not leave that space empty even when no imaging or laboratory tests were ordered.

Items 20 to 22: Diagnoses, consistency and other conditions

List up to 12 diagnoses with ICD-10 codes. For an occupational illness, specify the etiologic agent and duration of exposure, and answer whether chemical or toxic compounds were involved. Item 21 asks whether your findings and diagnosis are consistent with the patient's account of the injury or onset of illness, with an explanation if not. Item 22 asks about any other current condition that will impede or delay recovery.

Items 23 to 25: Treatment rendered, treatment plan and hospitalization

Item 23 describes the treatment rendered, using the reverse side if more space is required. Item 24 gives the treatment plan and estimated duration if further treatment is required. Item 25 applies only when the patient is hospitalized as an inpatient and asks for the hospital name and location, the date admitted and the estimated length of stay.

Item 26: Work Status

State whether the patient is able to perform his or her usual work by checking Yes or No. If No, enter the date the patient can return and mark whether that return is to regular work or to modified work, then specify the restrictions in the space provided at the bottom of Sheet 2.

Physician Signature and declaration (Sheet 3)

Sign with an original signature, not a stamp. The declaration states under penalty of perjury that the report is true and correct to the best of your knowledge and that you have not violated Labor Code section 139.3. Add your California license number, where the report was executed, the date (mm/dd/yyyy), your name, specialty, address and phone number. A fraud warning and DWC's privacy notice follow.

Common mistakes

  • Filing after the 5-day window; the form warns that failure to file a timely doctor's report may result in assessment of a civil penalty.
  • Stamping the physician signature; the signature line specifies an original signature and says do not stamp.
  • Leaving X-ray and laboratory results blank instead of stating none or pending, as item 19B asks.
  • Omitting the etiologic agent and duration of exposure for an occupational illness in item 20.
  • Sending a pesticide poisoning report only to the insurer; diagnosed or suspected cases also go to DIR, with a call to the local health officer within 24 hours.
  • Leaving the Social Security number blank without noting the worker has none; DWC may return or reject a form with required fields incomplete.

Submitting and payment

How to submit it
Within 5 days of the initial exam (5 working days under 8 CCR 9785), send two copies to the employer's workers' compensation insurer or the insured employer, by mail, fax, encrypted email, EDI or other means the claims administrator accepts. For diagnosed or suspected pesticide poisoning, also send a copy to DIR and phone the local health officer within 24 hours.
Who pays
The report is billed under California OMFS code WC001 but is not separately reimbursable, because 8 CCR 9789.14 includes its fee in the underlying evaluation and management service.

Good to know

  • Sign by hand: the line reads original signature, do not stamp, and the physician declares under penalty of perjury that the report is true and that Labor Code section 139.3 was not violated.
  • Failure to file a timely doctor's report may result in a civil penalty. Treatment of pesticide poisoning never counts as first aid, so those cases are always reported.
  • Item 20 takes up to 12 ICD-10 diagnoses; for an occupational illness, specify the etiologic agent and duration of exposure and note any chemical or toxic compounds involved.
  • The worker's Social Security number is required under Labor Code section 6409; if the worker has none, indicate that in the space provided for it.

Frequently asked questions

When is the Doctor's First Report due in California?

Within 5 days of the initial examination, for every occupational injury or illness, according to the form and 8 CCR 14003; 8 CCR 9785 phrases it as 5 working days. Emergency and urgent care physicians also file one after the initial visit, and each new primary treating physician files one. A late report may bring a civil penalty.

Can Form 5021 be filed electronically?

DWC runs an Electronic Reporting System for the Doctor's First Report under SB 1160, with an online system and EDI for high-volume filers such as hospitals. Participation is currently a voluntary pilot. A physician who files online with DWC is still responsible for sending a copy to the claims administrator, and DWC plans regulations to phase out paper filing.

Is the Doctor's First Report separately billable?

No. It is reported with OMFS code WC001, but 8 CCR 9789.14 lists it among reports that are not separately reimbursable because the fee is included in the evaluation and management service for the visit. By contrast, the PR-2 progress report is separately reimbursable under code WC002.

Who fills in the accident description on Form 5021?

Item 17 asks the patient to describe how the accident or exposure happened, naming the specific object, machinery or chemical. If the patient cannot, the doctor completes it immediately, and the form states that a patient's inability or failure to complete it does not affect his or her rights to workers' compensation under the California Labor Code.
