How is my PD percentage determined?

A doctor rates impairment after P&S or MMI. California then applies a formula using the injury, occupation, and age to set a permanent disability percentage.

How is my PD percentage determined?
A doctor determines your level of impairment after you reach Permanent and Stationary status or Maximum Medical Improvement. That impairment is then used in a rating formula that considers factors such as the injury, occupation, and age to calculate a permanent disability percentage.

Why occupation and age matter

Two workers with the same medical impairment can receive different PD ratings because the formula adjusts for the job’s physical demands and for age. That is why copying a coworker’s rating is rarely a reliable estimate of your own case.

This page is general education about California workers’ compensation—not legal advice. Your facts, dates, and medical reports control. Workplace Rights Advocacy focuses on civil employment claims. Benefit and medical disputes inside the workers’ compensation system are often best handled by a workers’ compensation attorney. If an employer is forcing you out, denying accommodations, or retaliating around a work injury, that may be an employment case we can evaluate.

Common questions

Answers we give on every page before you call. More detail is on our full FAQ page.

Do I have a case?
If you faced discrimination, harassment, retaliation, unpaid wages, wrongful termination, leave denial, or a refused disability accommodation, you may have claims. Whether your facts support a case depends on the evidence, deadlines, and applicable law—we evaluate that in consultation.
How much does it cost?
Initial consultations are typically free. If we take the matter, fees are usually explained in a written agreement before you hire us. Many employment cases are handled on contingency (see below).
Do you work on contingency?
In many employment matters, yes—attorney fees may be collected only if there is a recovery, subject to a signed fee agreement. Costs and fee arrangements can vary by case type; we confirm the terms up front.
How long will my case take?
Some matters resolve in months; contested lawsuits can take a year or longer through discovery, mediation, arbitration, or trial. Timing depends on the claims, court or arbitrator calendars, and whether the other side fights. See how long employment lawsuits take.
What should I bring?
Bring or upload what you have: a short timeline, pay stubs or time records, emails and texts, write-ups or reviews, medical or leave paperwork, and the names of witnesses or managers. See our documentation guide.
Free consultation?
Yes—initial consultations are typically free and confidential. Contacting us does not create an attorney–client relationship until there is a signed written agreement.
What happens after I contact you?
Our intake team reviews what you send, follows up if we need more detail, and screens deadlines and claim types. If the matter may be a fit, we schedule a consultation to discuss options, risks, and next steps—or we let you know promptly if we cannot help.
