Step 1: Reaching MMI Status
The DEU process cannot begin until a doctor declares that you have reached Maximum Medical Improvement (MMI). This means your condition is stable and not expected to get better or worse. The doctor will then issue a comprehensive report detailing your permanent limitations. This report is the foundational document that the DEU will eventually analyze to create your rating.
Step 2: The Request for Rating
Once the MMI report is ready, a request for a rating is submitted to the DEU. This can be done by your attorney, the insurance claims adjuster, or a judge. There are specific forms (like the “Request for Summary Rating Determination”) that must be filled out accurately. Any error on these forms, such as an incorrect job title, can lead to an inaccurate final rating.
Step 3: Assignment to a Rater
Some people ask some questions: “what is deu?” The file is then assigned to a Disability Evaluation Specialist at one of the DEU district offices. These specialists are experts in the California Rating Schedule. They review the medical report to ensure it meets the “substantial medical evidence” standard. If the report is too vague—for example, if it says “the worker has some pain” without quantifying it—the rater may ask for clarification.
Step 4: Applying the Modifiers
This is where the math happens. The rater starts with the Whole Person Impairment (WPI) from the medical report. They then apply the occupational group code (based on your job duties) and your age at the time of injury. For example, a 60-year-old construction worker will get a different adjustment than a 22-year-old receptionist for the exact same wrist injury.
Step 5: Using the Combined Values Chart
If you have injuries to multiple body parts, the rater doesn’t just add the percentages together (e.g., 10% + 10% does not equal 20%). Instead, they use a “Combined Values Chart” (CVC). This formula accounts for the fact that multiple disabilities overlap. The DEU’s expertise in navigating this chart is essential for getting a mathematically correct total disability percentage.
Step 6: Issuing the Rating Determination
After the calculations are complete, the DEU issues a formal document called a “Rating Determination.” This paper lists the impairment, the adjustments made, and the final permanent disability percentage. It also usually includes a breakdown of the total dollar value of the award and the weekly payment amount you should expect to receive.
Step 7: The Review Period
Once the rating is issued, both the injured worker and the insurance company have a short window to review it. If there is a “clerical error” (like a typo in your age), it can be fixed quickly. However, if you disagree with the doctor’s findings that the rater used, the process becomes more complicated and may require a legal “Declaration of Readiness” to go before a judge.
Step 8: Serving the Rating
The DEU “serves” (delivers) the rating to all parties involved. This officially puts the insurance company on notice regarding their financial liability. In many cases, once this document is received, the insurance company will begin making payments if they haven’t already. It is a major milestone that signifies the end of the medical recovery phase and the beginning of the financial resolution.
Step 9: Integration into the Settlement
The rating is then used to draft the final settlement papers. If you are doing a “Stipulated Award,” the DEU rating is essentially copied into the legal contract. If you are doing a “Compromise and Release,” the rating is used to justify the lump sum amount to the Workers’ Comp Judge who must sign off on the deal to make it official.
Conclusion: A Systematic Journey
The DEU process is a structured, step-by-step journey designed to take the guesswork out of disability benefits. While it can seem slow and overly technical, each step serves a purpose in protecting the rights of the worker. By following this breakdown, you can track where your case is in the pipeline and understand why each piece of medical evidence is so critical.
