Occupational Group 420

In the California 2005 PD Rating Schedule, occupational group 420 covers jobs such as BAKER, BUTCHER, ALL-ROUND, and CANVAS REPAIRER. Your occupational group sets the variant applied to each impairment, which adjusts the standard rating up or down before the age adjustment. Here a physical impairment raises the rating.

How group 420 adjusts a rating

Group 420 rating FAQ

What is occupational group 420 in California workers’ comp?
Occupational group 420 is one of the 45 groups in the 2005 Permanent Disability Rating Schedule. It covers jobs such as BAKER, BUTCHER, ALL-ROUND, and CANVAS REPAIRER. The group number sets the “occupational variant” applied to each impairment, which adjusts the standard rating up or down (PDRS Sections 4 and 5).
Does my occupational group change my permanent-disability rating?
Yes. After the whole-person impairment is converted to a standard rating, the occupational group applies a variant (C–J) that raises or lowers it before age adjustment. For group 420, a physical impairment such as a spine or knee injury raises the rating relative to the standard.
How much does group 420 adjust a 20% standard rating?
Spine: 25% (+5); Shoulder: 22% (+2); Knee: 22% (+2); Wrist / carpal tunnel: 27% (+7); Grip / pinch strength: 25% (+5); Psychiatric: 20% (±0); Hearing loss: 16% (-4); Respiratory / lungs: 22% (+2).
Is this a legal PD rating?
No — it’s an estimate for informational use. Always confirm the occupational variant and final rating against the DEU. RateString rates strict AMA Guides values under the 2005 PDRS.
