What Is a Workers' Compensation Disability Rating Chart?
A disability rating chart is a standardized table that assigns a percentage to an employee's permanent impairment after a work‑related injury. In West Virginia, the chart translates medical findings into a rating that determines the amount of permanent disability (PD) benefits the worker is entitled to receive.

How West Virginia Calculates Disability Ratings
West Virginia follows the American Medical Association's Guides to the Evaluation of Permanent Impairment (AMA Guides). The process involves:
- Medical evaluation by a qualified physician.
- Assignment of an impairment rating for each affected body part.
- Application of the AMA's Combined Values Table to derive a single overall rating.
The resulting percentage (e.g., 12%) is the worker's disability rating.
Key Components of the WV Disability Rating Chart
The chart is organized by body region and injury type. Each entry lists:
- Injury description (e.g., "fracture of the radius").
- Maximum allowable rating for that injury.
- Modifiers for factors such as age or pre‑existing conditions.
Example Entry
Injury: Complete loss of thumbMaximum rating: 20%Modifier: -2% if the worker is over 55.
How the Rating Translates to Benefits
Once the final rating is set, West Virginia workers' compensation law uses a formula to calculate weekly PD benefits:
| Factor | Calculation | Explanation |
|---|---|---|
| Average Weekly Wage (AWW) | Sum of the worker's wages for the 52 weeks prior to injury ÷ 52 | Base earnings used for all benefit calculations. |
| Disability Percentage | Final rating from the chart (e.g., 12%) | Determines the proportion of the AWW payable. |
| Benefit Rate | AWW × Disability Percentage × 0.66 | West Virginia caps PD benefits at two‑thirds of the AWW. |
The resulting amount is paid weekly for the duration of the disability, which may be a set number of weeks or for life, depending on the rating.
Common Rating Percentages and What They Mean
- 0%–5%: Minor impairment, usually no PD benefits.
- 5%–15%: Low‑level permanent disability; benefits may be limited to a few weeks.
- 15%–30%: Moderate impairment; benefits continue for several years.
- 30%+ : Severe impairment; may qualify for lifetime benefits.
Steps to Contest or Appeal a Rating
If a worker believes the rating is too low, West Virginia law provides a clear appeals process:
Documenting all medical records and maintaining clear communication with the employer and insurer strengthens the case.
