Impairment · 2005 PDRS Section 2
Nervous system & nerve injury: PD rating
Brain, spinal cord, and peripheral nerves — including carpal tunnel and other entrapment neuropathies. These arrive directly as a whole-person impairment (WPI) percentage.
WPI → PD rating
Example — a 12% WPI peripheral-nerve impairment: 12 × 1.4 = 17 standard rating (DOI ≥ 2013), before the occupational and age adjustments.
The occupational and age steps and the final dollar figure depend on the specific job and birth date — the calculator computes them exactly.
How nervous-system ratings work: Chapter 13 of the AMA Guides rates the brain and nerves by function — consciousness disorders (13.01.00.00), episodic disorders, motor, sensory, and the cranial nerves each carry their own impairment numbers — while peripheral entrapments like carpal tunnel typically rate through the extremity chapters instead. Reported WPI runs the standard pipeline: the 1.4 adjustment, occupational variant, and age.

Nervous system rating FAQ
How is a nervous system & nerve injury injury rated for permanent disability in California?
These arrive directly as a whole-person impairment (WPI) percentage. The WPI is multiplied by 1.4 to get the standard rating (dates of injury on or after 2013 under SB 863), then adjusted for the worker’s occupation and age, apportioned under Lab. Code §4663, and combined with any other impairments. Example — a 12% WPI peripheral-nerve impairment: 12 × 1.4 = 17 standard rating (DOI ≥ 2013), before the occupational and age adjustments.
What body parts are in the Nervous system & nerve injury section of the PDRS?
The 2005 PDRS lists 34 impairments here. Brain, spinal cord, and peripheral nerves — including carpal tunnel and other entrapment neuropathies.
Does the occupation change a nervous system & nerve injury rating?
Yes — after the ×1.4 step, the occupational group applies a variant that raises or lowers the standard rating. See the occupation pages for how each group treats this region.
Is this a legal PD rating?
No — it’s an estimate for informational use. Confirm every rating against the DEU. RateString rates strict AMA Guides 5th-edition values under the 2005 PDRS.
