Rating String Decoder
Every rated California workers’ compensation case produces a string like
15.03.01.00 – 8 – [1.4]11 – 340G – 13 – 15.
It determines your money. Almost nobody explains how to read it. Paste yours.

These are published examples, not invented ones.
What the six segments are
| Segment | Example | What it is |
|---|---|---|
| 1 | 15.03.01.00 | Impairment number — body part, region, method, condition |
| 2 | 8 | Whole person impairment, from your doctor |
| 3 | [1.4]11 | Statutory modifier and the adjusted figure |
| 4 | 340G | Occupational group and variant letter |
| 5 | 13 | Rating after the occupational adjustment |
| 6 | 15 | Final permanent disability, after age adjustment |
Before you rely on any of this
- This decodes a rating. It does not produce one. Only a physician determines whole person impairment; only the Disability Evaluation Unit or a judge issues a rating.
- Impairment is not disability. Your WPI is not your PD percentage, and the gap between them is most of what this tool exists to explain.
- Apportionment can change everything. Labor Code §§ 4663 and 4664 — and after City of Jackson and Lindh, even an asymptomatic pre-existing or genetic condition can support it.
- Your date of injury controls which law applies. Before 2005, 2005–2012, and 2013 onward are three different systems.
- Multiple body parts do not simply add. The Combined Values Chart applies unless you meet the Vigil standard.
- The rating may be rebuttable — Almaraz/Guzman, Ogilvie/Dahl, and Kite/Vigil can move it in either direction.
- Using this tool does not create an attorney–client relationship.
