Permanent Disability Ratings 2025: How Comp Calculates Your Award

## When Recovery Stops Short

Many workplace injuries heal completely. Others leave permanent damage, a stiff knee, a weakened back, a lost finger, or chronic pain. When that happens, workers compensation pays a permanent disability award. The amount turns on a number called the permanent impairment rating, expressed as a percentage. Understanding how that percentage is set and turned into dollars is essential because the difference between a 5 percent and a 15 percent rating can be tens of thousands of dollars.

Maximum Medical Improvement Comes First

A permanent rating cannot be assigned until you reach maximum medical improvement, or MMI. MMI is the point where your condition has stabilized and further treatment will not significantly improve it. It does not mean you are pain-free; it means your condition is as good as it is going to get. Once a doctor declares MMI, the rating process begins.

How the Impairment Rating Is Set

A physician evaluates your permanent loss of function and assigns a whole-body or body-part impairment percentage, usually following a standardized guide such as the AMA Guides to the Evaluation of Permanent Impairment. The rating reflects measurable loss, range of motion, strength, nerve function, and similar factors. The doctor's rating is an opinion, and reasonable physicians often disagree, which is why disputes are common.

Two Kinds of Permanent Disability

1. **Permanent partial disability (PPD).** You have lasting impairment but can still work in some capacity. Most permanent ratings fall here.
2. **Permanent total disability (PTD).** You cannot return to any gainful employment. PTD awards are far larger and may pay lifetime benefits.

Scheduled vs Unscheduled Injuries

Many states use a schedule that assigns a set number of weeks of benefits to specific body parts. For example, the loss of a hand might be worth a fixed number of weeks of compensation. An injury not on the schedule, such as a back or a whole-body condition, is unscheduled and valued differently, often based on loss of earning capacity. The distinction matters enormously because the same functional loss can be valued very differently depending on which category applies.

Turning the Percentage into Dollars

The basic formula in many states is impairment percentage multiplied by a number of weeks multiplied by your compensation rate. For example, a 10 percent whole-body rating in a state that allots 400 weeks for total disability yields 40 weeks of benefits, and at a 600 dollar weekly rate that is 24,000 dollars. The actual formulas vary widely by state, but the structure is similar: a higher rating means more weeks and more money.

How to Challenge a Low Rating

Insurers often send you to a doctor who issues a conservative rating. You have options:

• **Get an independent medical examination** from a physician who will evaluate you thoroughly.
• **Provide complete records** so the rating reflects every component of your loss.
• **Ensure all affected body parts are rated**, not just the primary one.
• **Argue for the correct category**, scheduled or unscheduled, whichever values your injury fairly.
• **Hire a [workers comp attorney](/lawyer)** who knows how ratings are inflated and deflated.

Steps in the Rating Process

Step one: complete treatment and reach MMI. Do not rush; a premature rating may understate permanent loss that later becomes apparent.

Step two: obtain a thorough impairment evaluation.

Step three: compare the insurer's rating to an independent one.

Step four: dispute through the comp board if the ratings differ materially.

Step five: consider whether a lump-sum settlement or ongoing payments serves you better.

Realistic Value Ranges

• 5 percent rating on a minor extremity injury: 5,000 to 20,000 dollars.
• 15 percent whole-body back rating: 30,000 to 90,000 dollars depending on state and wage.
• Permanent total disability: often hundreds of thousands of dollars or lifetime benefits.

Frequently Asked Questions

Who decides my rating? A physician assigns it, but you can dispute it, and ultimately a comp judge can decide between competing ratings.

Can my rating change later? In some states a worsening condition can be reopened within a time limit. Confirm your state's reopening rule.

Should I take a lump sum? It depends. A lump sum gives certainty but may close future medical. Get advice before settling.

Does the rating affect my job? The rating values your loss; it does not by itself end your employment, though return-to-work issues are separate.

A permanent disability rating is the financial heart of a serious comp claim. A few percentage points are worth real money, so never accept the first rating without scrutiny.
