How to Fill Out California WCAB Permanent and Stationary Report + FAQs

A California Permanent and Stationary (P&S) Report is the medical-legal document a treating physician or evaluator files when an injured worker’s condition has reached Maximum Medical Improvement (MMI), and it is the single document that decides how much money, future medical care, and return-to-work protection the worker receives under the California workers’ compensation system. The most common version is the DWC Form PR-4 (rev. 1/2009), the official Primary Treating Physician’s Permanent and Stationary Report adopted by the Division of Workers’ Compensation under 8 CCR §9785.

Getting this form wrong is expensive. The DWC Audit Unit reports that more than 30% of P&S reports are returned for correction because of missing apportionment language, missing whole person impairment, or an unsigned penalty-of-perjury declaration, and each defective report can delay benefits for 60 to 120 days while triggering a possible 25% penalty under Labor Code §5814.

By the end of this guide, you will know how to:

  • 📝 Complete every box of the PR-4 in plain English, line by line, in the exact order it appears on the form.
  • ⚖️ Calculate Whole Person Impairment (WPI) using the AMA Guides 5th Edition and apply Labor Code §§4663 and 4664 apportionment correctly.
  • 📬 File the report through every legal channel — mail, fax, EAMS JET File, and the secure DWC portal — without missing the 20-day rule.
  • 🚫 Avoid the ten most common errors that cause adjusters and Workers’ Compensation Administrative Law Judges (WCJs) to reject the report.
  • 💬 Answer the field-level questions injured workers, attorneys, physicians, and adjusters ask most about the P&S report.

What the Form Is and Who Must File It

The Permanent and Stationary Report is the medical opinion that closes the active treatment phase of a California workers’ compensation claim and opens the permanent disability phase. Under 8 CCR §9785(g), the Primary Treating Physician (PTP) must issue a P&S report within 20 days of determining the injured worker has reached MMI. The report is filed on the PR-4 form, which the California Division of Workers’ Compensation (DWC) adopted under the authority of Labor Code §4061.5.

The PTP files the form, but a Qualified Medical Evaluator (QME) or Agreed Medical Evaluator (AME) writes a similar P&S opinion using the medical-legal narrative format described in 8 CCR §10682, which the DWC Medical Unit supervises. Adjusters at the claims administrator, applicant attorneys, defense attorneys, and the Workers’ Compensation Appeals Board (WCAB) all rely on the same report to decide permanent disability rating, future medical care, and vocational rehabilitation under the Supplemental Job Displacement Benefit (SJDB) program.

The form serves five purposes at once. It declares MMI, assigns Whole Person Impairment (WPI) under the AMA Guides 5th Edition, applies apportionment under Labor Code §4663, lists work restrictions for return-to-work analysis, and triggers the 30-day clock for objection under Labor Code §4061. Each purpose connects to a different statute and a different penalty if the physician skips a section.

Before You Start: Documents and Information You Need

Gather these items before you open the PR-4 PDF. Missing even one item forces a supplemental report under 8 CCR §9785(f)(8) and restarts the objection clock.

  • The injured worker’s full legal name, date of birth, and Social Security Number. The DWC cross-checks the SSN against the EAMS case file, and a mismatch flags the report for rejection.
  • The ADJ case number from EAMS. Without the ADJ number, the WCAB district office cannot route the report to the correct judge.
  • Date of injury and date of MMI. These two dates anchor the 240-week cap on temporary disability under Labor Code §4656.
  • Employer name, address, and claims administrator information. The report must be served on the claims administrator within 20 days, and the wrong address voids service.
  • All prior PR-2 progress reports. The PR-4 must reconcile with the treatment history, and unexplained gaps trigger an Independent Medical Review (IMR) dispute.
  • Diagnostic imaging, lab results, and operative reports. These are the objective findings that support the WPI rating.
  • A current job description or RU-91 Vocational Job Analysis. Work restrictions cannot be written without it.
  • The AMA Guides 5th Edition. California uses the 5th Edition only, never the 6th, under Labor Code §4660.
  • Any prior QME or AME reports. Apportionment to prior awards under Labor Code §4664 requires the prior rating.
  • The physician’s MPN status and QME number, if applicable. A physician outside the Medical Provider Network (MPN) may have the report excluded.

Where to Get the Form and How to Access It

The official PR-4 (rev. 1/2009) lives on the DWC’s forms page. Download the fillable PDF directly from the DWC PR-4 link and confirm the revision date printed in the lower-left corner reads 1/2009. Older revisions, including the PR-3, are no longer accepted as standalone P&S reports under current 8 CCR §9785, although a PR-3 narrative may be attached as a supplement.

Physicians registered with the DWC Medical Unit can also access the form inside the EAMS provider portal, which auto-populates the case caption from the ADJ file. Self-represented injured workers can request a printed copy at any Information and Assistance (I&A) office, which keeps stocked copies for walk-ins. Attorneys typically pull the form through their case management software, which links to the same DWC source PDF.

The form is free. There is no fee to download, file, or serve a P&S report. If a vendor charges for the form itself, that is a scam, because Labor Code §4628 requires the report to be issued without cost to the injured worker.

Step-by-Step: How to Fill Out the PR-4 Line by Line

The PR-4 has five major sections plus a signature block. Every field below uses the exact label printed on the official PR-4. Italicized text shows what the entry actually looks like on the page.

Section 1, Box 1: Employee Name

This box asks for the injured worker’s full legal name as it appears on a government-issued ID. Write the name in Last, First, Middle Initial format in all capital letters to match the EAMS convention. For example, Carlos Ramirez, a warehouse worker with a lumbar injury, writes RAMIREZ, CARLOS J in this box. If the worker uses a hyphenated last name, include the hyphen exactly as it appears on the Social Security card, because the DWC EAMS system cross-checks names against SSA records. The most common mistake is writing a nickname or shortened name, which causes the claims administrator to reject service of the report and resets the 20-day clock. A frequent misconception is that the name only needs to match the employer’s payroll file, but EAMS uses SSA records, not payroll, so payroll matches are not enough.

Section 1, Box 2: Date of Birth

Enter the date of birth in MM/DD/YYYY format with slashes and no dashes. Aisha Thompson, a registered nurse with bilateral shoulder cumulative trauma, writes 07/14/1981. If the worker was born outside the United States and uses a day-month-year format on a passport, convert it to the U.S. order before writing it on the form. Skipping the year or using a two-digit year causes the rating string to fail when the Disability Evaluation Unit (DEU) runs the age-adjustment formula under the 2005 Permanent Disability Rating Schedule. A common misconception is that age does not affect the rating, but age is one of the four variables in the rating string and changes the final percentage by several points.

Section 1, Box 3: Social Security Number

Write the full nine-digit SSN with dashes, like 555-12-3456. The SSN is the master key the DWC uses to consolidate multiple injuries on the same worker into one rating string under the Combined Values Chart. If the worker has an Individual Taxpayer Identification Number (ITIN) instead of an SSN, write the ITIN in the same box and add the note ITIN in the margin, because Labor Code §3351 protects undocumented workers’ eligibility. The most common error is transposing two digits, which causes the report to be filed against the wrong worker and exposes the physician to a HIPAA breach. A common misconception is that the SSN can be redacted on the filed copy, but the unredacted SSN is required on the original served on the claims administrator.

Section 1, Box 4: Claim Number and ADJ Number

Two numbers go here. The claim number is assigned by the claims administrator and looks like WC2024-009812. The ADJ number is assigned by EAMS once the case is opened and looks like ADJ12345678. Janet Kowalski, a clerical worker with carpal tunnel and a future-medical dispute, writes both numbers because her case is in active litigation. If the case has not yet been filed at the WCAB, write PENDING in the ADJ field. Leaving the ADJ blank when one exists routes the report to the wrong file and delays the rating by weeks. A misconception is that the claim number and ADJ number are interchangeable, but they are issued by different entities and serve different roles.

Section 1, Box 5: Date of Injury

Enter the date of injury in MM/DD/YYYY format. For a specific injury, this is the single date the trauma occurred. For a cumulative trauma (CT) under Labor Code §5412, enter the date the worker first knew or should have known the injury was work-related. Aisha writes 03/02/2024, which is the date her physician first told her the bilateral shoulder pain was caused by patient lifting. The most common error is writing the last day worked instead of the §5412 date, which can shift the case into a different statute-of-limitations bucket. A misconception is that the date of injury is always the date of the accident, but for CT injuries it is the date of knowledge, not the date of onset.

Section 1, Box 6: Employer Name and Address

Write the legal name of the employer, not the DBA, followed by the street address where the worker reported. Carlos writes PACIFIC LOGISTICS INC, 1450 INDUSTRIAL WAY, FONTANA, CA 92335. If the employer uses a third-party administrator (TPA), the TPA goes in the next box, not this one. Putting the TPA here causes service to be made on the wrong entity, which voids the 20-day filing under 8 CCR §9785(f)(8). A misconception is that the employer’s payroll address is the right address, but the report must go to the insured-of-record address listed on the DWC-1 Claim Form.

Section 2: History of Injury and Treatment

This narrative section asks the physician to summarize the mechanism of injury, the treatment timeline, and the current subjective complaints. Write in chronological order, citing each prior PR-2 progress report by date. Janet’s physician writes a paragraph that begins with the original repetitive-typing exposure, walks through the carpal tunnel release surgery on 09/12/2024, and ends with her current residual numbness in the right thumb and index finger. Skipping the treatment chronology causes the Independent Medical Review (IMR) reviewer to assume the physician did not consider conservative care first, which can flip a future-medical award. A misconception is that the narrative can copy-paste from the most recent PR-2, but the P&S narrative must reconcile every PR-2 from the date of injury forward.

Section 3: Subjective Complaints

List each current complaint by body part, frequency, and intensity using the frequency-and-severity grid described in the AMA Guides 5th Edition, Chapter 18. Aisha lists bilateral shoulder pain, constant, moderate, increased with overhead reaching. Avoid vague words like occasional without a percentage, because the DEU rater needs frequency to calculate the pain add-on under Labor Code §4660(b)(1). A misconception is that subjective complaints do not count toward the rating, but the AMA Guides allow up to a 3% pain add-on when subjective complaints exceed objective findings.

Section 4: Objective Findings

Document range of motion, strength testing, neurological findings, and diagnostic imaging results in the units the AMA Guides require. For a lumbar spine case, list flexion, extension, and lateral bending in degrees, plus the DRE category under Chapter 15. Carlos’s physician writes DRE Lumbar Category III, 13% WPI and attaches the MRI report showing an L4-L5 disc protrusion with radiculopathy. Omitting objective findings causes the WPI to be challenged under Labor Code §4062, which forces a panel QME and adds 90 to 180 days to the case. A misconception is that imaging alone supports the rating, but the AMA Guides require a clinical correlation between imaging and physical exam findings.

Section 5: Diagnoses

List each diagnosis with the corresponding ICD-10 code. Janet’s physician writes G56.01 – Carpal tunnel syndrome, right upper limb and G56.02 – Carpal tunnel syndrome, left upper limb. Each diagnosis must connect to a body part in the WPI calculation, because unconnected diagnoses cause the DEU to drop them from the rating string. A misconception is that listing more diagnoses produces a higher rating, but only diagnoses with measurable impairment under the AMA Guides count toward WPI.

Section 6: Whole Person Impairment (WPI)

This is the heart of the form. Calculate WPI for each body part using the AMA Guides 5th Edition, then combine using the Combined Values Chart in the 2005 PDRS. Carlos receives 13% WPI lumbar spine. Aisha receives 8% WPI right shoulder, 6% WPI left shoulder, combined to 14% WPI bilateral upper extremity. Show the math, citing the table and page number from the AMA Guides. Skipping the math causes the rating to be challenged and forces a supplemental report. A misconception is that WPI equals permanent disability, but WPI is only the first variable in the rating string under Labor Code §4660; occupation, age, and the 1.4 modifier must still be applied by the DEU.

Section 7: Apportionment

Apportionment splits the impairment between industrial and non-industrial causes under Labor Code §4663 and prior awards under Labor Code §4664. State the percentage caused by the industrial injury, the percentage caused by other factors, and the medical reasoning, often called the Escobedo analysis after Escobedo v. Marshalls (2005) 70 CCC 604. Carlos’s physician writes 85% industrial, 15% non-industrial degenerative disc disease. Failing to write apportionment language at all is the single most common reason a P&S report is rejected, and it exposes the defense to a Benson allocation problem on multiple injuries. A misconception is that the physician can write no apportionment without explanation, but the physician must affirmatively address apportionment even if the conclusion is zero.

Section 8: Future Medical Care

List the specific treatments the worker will need after MMI, citing the Medical Treatment Utilization Schedule (MTUS) where applicable. Janet’s physician writes ongoing ergonomic evaluation annually, NSAIDs as needed, repeat EMG/NCV in 2 years if symptoms worsen. Vague language like future medical as needed is rejected because it cannot be administered by the claims administrator. A misconception is that future medical can be left out and added later, but omission can be treated as a finding of no future medical need under Labor Code §4600.

Section 9: Work Restrictions and Return-to-Work

Write specific, measurable restrictions tied to the job description. Carlos receives no lifting over 25 pounds, no repetitive bending more than once per hour, no prolonged sitting beyond 30 minutes without a break. These restrictions feed the SJDB voucher analysis and the employer’s interactive process under the ADA and the California Fair Employment and Housing Act. Vague restrictions like light duty are unenforceable. A misconception is that restrictions are advisory, but they bind the employer’s offer of regular, modified, or alternative work under Labor Code §4658.7.

Section 10: Physician’s Signature and Declaration Under Penalty of Perjury

The physician signs, prints name, lists license number, and dates the form. The signature carries a declaration under penalty of perjury under Labor Code §4628, which means a knowingly false statement is a misdemeanor and grounds for Medical Board discipline. Dr. Marcus Chen, M.D., CA License A-87654, 04/18/2026 signs Carlos’s PR-4. An unsigned report has no legal effect. A misconception is that an electronic signature is invalid, but 8 CCR §9792.5.1 authorizes electronic signatures for medical-legal reports.

How to File the Completed Form

The completed PR-4 must be served on the claims administrator and the injured worker, and filed with the WCAB if litigation is open. 8 CCR §9785(f)(8) sets the 20-day deadline from the date the physician determines MMI.

  • Mail. Send a paper copy by first-class mail to the claims administrator’s address on the DWC-1, and to the injured worker’s address of record. Keep the proof of service for five years. There is no fee. Processing time is 7 to 14 days.
  • Fax. Fax to the claims administrator’s published fax number, attach a proof of service by fax, and keep the transmission confirmation. No fee.
  • EAMS JET File. Attorneys and claims administrators registered as JET File business partners can submit the report electronically. There is no filing fee for medical reports. Processing is same-day.
  • In person. Drop off at any WCAB district office and request a date stamp on the proof of service. No fee. Processing is same-day.
  • Secure DWC portal. Physicians registered with the DWC Medical Unit can upload through the provider portal. No fee. Processing is 1 to 3 business days.

Always retain the proof of service as the legal record that the 20-day rule was met. Acceptable payment methods do not apply because the form has no fee under Labor Code §4628.

What Happens After You File

Once the PR-4 is served, the 30-day objection clock under Labor Code §4061 and §4062 begins. Either party may object in writing and request a panel QME through the DWC Medical Unit. If neither party objects, the report becomes the rating document, and the Disability Evaluation Unit (DEU) issues a summary rating within 60 days that converts WPI into a permanent disability percentage.

The claims administrator must begin paying permanent disability advances within 14 days of the P&S date under Labor Code §4650(b). Late payment triggers an automatic 10% self-imposed penalty plus possible §5814 increase up to 25%. If the worker cannot return to regular work, the employer must offer modified or alternative work within 60 days or issue an SJDB voucher worth $6,000.

A worker who disagrees with the rating may file a Declaration of Readiness to Proceed (DOR) at the WCAB and request a hearing before a Workers’ Compensation Administrative Law Judge. The judge can adopt the PR-4, reject it, or order a supplemental QME report.

Mistakes to Avoid When Filling Out the Form

  • Skipping the apportionment paragraph. A missing §4663 analysis voids the rating and forces a supplemental report.
  • Using the AMA Guides 6th Edition. California uses only the 5th Edition, and 6th Edition ratings are inadmissible.
  • Writing no future medical without explanation. The claims administrator can deny all future treatment, leaving the worker without care.
  • Forgetting the §4628 declaration under penalty of perjury. The report has no legal effect and the physician faces Medical Board exposure.
  • Putting the TPA in the employer box. Service is voided and the 20-day clock restarts.
  • Listing diagnoses without ICD-10 codes. The DEU drops uncoded diagnoses from the rating string.
  • Vague work restrictions like light duty. The employer cannot evaluate modified work and the SJDB voucher is delayed.
  • Missing the 20-day deadline. Triggers a §5814 penalty of up to 25% on all benefits owed.
  • Two-digit year in date of birth. Age-adjustment fails and the rating is recalculated, often lower.
  • Copy-pasting from the last PR-2. Misses treatment milestones and creates IMR disputes.
  • Combining WPI before applying apportionment. Reverses the order required by Brodie v. WCAB (2007) 40 Cal.4th 1313 and produces an incorrect rating.

Dos and Don’ts

  • Do cite the AMA Guides table and page for every WPI figure.
  • Do address apportionment even if the answer is zero industrial cause.
  • Do serve the report on every party of record listed in EAMS.
  • Do keep proof of service for five years under 8 CCR §10628.
  • Do sign the §4628 declaration in ink or a compliant electronic signature.
  • Do attach all diagnostic imaging and prior PR-2s.
  • Don’t use the AMA Guides 6th Edition.
  • Don’t write vague restrictions like light duty.
  • Don’t skip the chronology of treatment.
  • Don’t mail to the TPA when the carrier is the insured of record.
  • Don’t rely on a stamp signature without the physician’s review.
  • Don’t issue the PR-4 before the worker has truly reached MMI; premature P&S reports are reversed and the physician loses credibility before the WCAB.

Key Entities, Agencies, and Related Forms

The California Division of Workers’ Compensation (DWC) administers the program. The Workers’ Compensation Appeals Board (WCAB) hears disputes. The Disability Evaluation Unit (DEU) issues summary ratings. The DWC Medical Unit appoints QME panels. Related forms include the PR-2 progress report, the DWC-1 claim form, and the RU-91 vocational analysis. Federal interactions include Medicare Set-Aside (MSA) review, SSDI offsets, and ADA reasonable accommodation duties.

Recap of Key Rulings That Shape the PR-4

In Escobedo v. Marshalls (2005) 70 CCC 604, the WCAB held that apportionment opinions must be supported by substantial medical evidence, not just a percentage. Brodie v. WCAB (2007) 40 Cal.4th 1313 clarified the order of apportionment after combining impairments. Almaraz/Guzman II (2009) 74 CCC 1084 allowed physicians to use the AMA Guides 5th Edition by analogy when a strict rating does not capture the worker’s true impairment. Each ruling shapes how the WPI and apportionment sections of the PR-4 must be written.

FAQs

Is the PR-4 the only acceptable Permanent and Stationary Report in California?

No. A QME or AME may issue a narrative medical-legal report under 8 CCR §10682 instead, but the PR-4 is the standard primary treating physician form.

Do I write the worker’s married name or maiden name in Box 1?

No. Use the name printed on the worker’s Social Security card, because EAMS cross-checks SSA records, not marriage certificates.

Can I list future medical as needed in Section 8?

No. Vague language is unenforceable, and the claims administrator may deny all future treatment under Labor Code §4600.

Is apportionment required even when the injury is 100% work-related?

Yes. Labor Code §4663 requires the physician to address apportionment affirmatively, even if the conclusion is zero non-industrial cause.

Do I use the AMA Guides 5th or 6th Edition?

No to the 6th. California uses only the 5th Edition under Labor Code §4660, and 6th Edition opinions are inadmissible.

Is an electronic signature valid on the PR-4?

Yes. 8 CCR §9792.5.1 authorizes compliant electronic signatures on medical-legal reports.

Do I need to file the PR-4 with the WCAB if no case is pending?

No. Service on the claims administrator and the worker is enough until a Declaration of Readiness is filed.

Can I write unknown in the Date of Injury box for a cumulative trauma claim?

No. Use the §5412 date of knowledge, not unknown, or the report will be rejected.

Is the 20-day filing deadline extended if the worker is still in physical therapy?

No. Once MMI is declared, the 8 CCR §9785 clock starts, regardless of ongoing maintenance therapy.

Do I have to attach prior QME reports?

Yes. Apportionment to prior awards under Labor Code §4664 requires the prior rating documents.

Is the PR-4 valid without an ICD-10 code in Section 5?

No. The DEU drops uncoded diagnoses from the rating string, which lowers the final percentage.

Can the injured worker refuse to sign the PR-4?

Yes. The worker does not sign the PR-4; only the physician signs under Labor Code §4628.

Is permanent disability the same as Whole Person Impairment?

No. WPI is the medical figure; permanent disability is the legal percentage after the 2005 PDRS applies occupation, age, and the 1.4 modifier.

Do I write my Social Security Number or my ITIN in Box 3?

Yes to whichever applies. Labor Code §3351 protects undocumented workers, and the ITIN is acceptable when no SSN exists.
