The Definition of a DEU Rating
A DEU rating is a numerical value, expressed as a percentage, that represents your level of permanent impairment. In California, this number determines how many weeks of permanent disability benefits you are entitled to. It is the result of a calculation performed by the Disability Evaluation Unit using medical evidence, your age, and your job duties.
When the Rating Happens
A rating does not happen immediately after an injury. It occurs only after you have reached “maximum medical improvement.” This means your condition is unlikely to change significantly with further treatment. At this point, your doctor writes a “Permanent and Stationary” report. This report is the raw material that the DEU uses to construct your final disability rating.
The Role of the AMA Guides
California law requires that ratings be based on the 5th Edition of the AMA Guides to the Evaluation of Permanent Impairment. Doctors must describe your limitations using the specific language found in these guides. If the doctor fails to follow these standards, the DEU may return the report or issue a deu rating that doesn’t reflect your true level of disability.
Age and Occupation Adjustments
One unique aspect of the DEU rating is the adjustment for age and occupation. Younger workers generally receive lower ratings for the same injury because they have more time to adapt to a disability. Conversely, if your job required heavy lifting and you suffered a back injury, your rating will be adjusted upward because the injury has a greater impact on your specific career path.
The Rating Formula
The DEU uses a specific formula: (Impairment) + (Occupation) + (Age) = Final PD Rating. This systematic approach is designed to remove subjectivity from the process. However, the input—the medical report—is where most errors occur. Workers should ensure their doctor fully understands the physical demands of their job before the final report is sent to the DEU for rating.
Permanent Disability Benefits
Once the DEU issues a rating, that percentage is converted into a dollar amount. Each “point” of disability corresponds to a set number of weeks of payments. For example, a 10% rating pays out for fewer weeks than a 30% rating. The weekly rate is also capped by state law, depending on the date of your injury and your average weekly wages.
The Difference Between PD and TD
It is important to distinguish between Temporary Disability (TD) and Permanent Disability (PD). TD is paid while you are recovering and unable to work. PD, which is determined by the DEU rating, is paid after your condition has stabilized. Some workers are surprised to find that their PD payments are lower than their TD payments, making the DEU rating even more critical.
Unrepresented vs. Represented Workers
If you have an attorney, they will often negotiate the rating or hire their own expert to counter the DEU’s assessment. If you are unrepresented, the DEU’s “Summary Rating” is usually the final word. Unrepresented workers should be extra cautious, as they do not have a legal advocate to check the DEU’s math or challenge a doctor’s conservative assessment.
Commutation of Benefits
In some cases, you can request that your PD benefits be paid in a lump sum rather than weekly installments. This is called a commutation. To do this, you usually need an official DEU rating to prove the total value of the award. A judge must approve this to ensure it is in the best interest of the injured worker.
Conclusion: Knowledge is Power
Understanding how the DEU arrives at a rating empowers you to advocate for yourself. If you see a rating that seems low, you can ask questions about how your age or job title was factored in. The DEU rating is the ultimate roadmap for your financial recovery, and knowing how it is drawn is essential for every injured worker in California.
