California Workers’ Compensation — Permanent Disability Rating Calculator

Case Information

Variant letters (C–J) are looked up automatically from the PDRS Section 4 Occupational Variants table using the selected body part and occupational group. Look up the employee’s group number in PDRS Section 3 (e.g., 470 = furniture assembler, heavy; 111 = general clerical).

Impairments

Pain add-on (AMA Guides Ch. 18): add up to 3% WPI into the body part’s WPI before entry — it is not rated as a separate impairment. Variant defaults to the Section 4 lookup; use the dropdown to override (e.g., per a rater’s instruction or a Section 4 footnote).
