What is a Permanent Partial Disability Rating in Missouri?

What Is a Permanent Partial Disability Rating in Missouri?

Quick answer: Quick answer: A permanent partial disability (PPD) rating in Missouri is a percentage used to measure the permanent disability caused by a work-related injury. That percentage, along with the body part affected and the applicable compensation rate, helps determine the amount of PPD compensation an injured worker may receive. 

If you were hurt on the job and your recovery has stalled, you may hear the term “permanent-partial disability rating.” It sounds technical, but it directly affects the money you receive. This rating turns your injury into a number, and that number shapes your disability compensation.

Understanding how the rating works helps you spot a lowball offer and protect what you’re owed. Below, Labovitz Law Firm breaks down how Missouri assigns these ratings, how benefits are calculated, and what to do if you disagree with the number.

What Is a Permanent Partial Disability Rating?

A permanent-partial disability rating is a percentage assigned by a doctor to describe your lasting physical loss. For example, a doctor might rate a wrist injury as a “10% loss of use of the wrist.”

You only receive this rating once you reach Maximum Medical Improvement (MMI). MMI is the point where your condition has stopped improving, even with continued treatment. In other words, your doctor has determined that your body has healed as much as it’s going to.

Waiting for MMI matters. A rating given too early may not reflect the true, permanent extent of your injury.

How Missouri Calculates PPD Ratings

Your doctor plays the central role here. After you reach MMI, the doctor evaluates your permanent physical loss and assigns a disability percentage to the affected body part. Missouri law then sorts injuries into two categories:

  • Scheduled injuries: These affect specific body parts, and each part carries a set statutory week limit. An arm, for instance, is valued at 232 weeks.
  • Non-scheduled injuries: These affect the “body as a whole,” such as a back or spine injury. Non-scheduled injuries carry a maximum of 400 weeks.

The category your injury falls into changes the math behind your disability compensation.

How Are PPD Benefits Calculated in Missouri?

Missouri uses a straightforward formula to convert your rating into a dollar amount:

  • Statutory Weeks x Disability Percentage x Weekly Compensation Rate

Here’s what each piece means:

  • Statutory Weeks: The number tied to your injured body part (such as 232 weeks for an arm).
  • Disability Percentage: The rating your doctor assigned (such as 10%).
  • Weekly Compensation Rate: Set at two-thirds (66.67%) of your average weekly wage, up to state maximum limits.

Say you have a 10% disability rating to your arm. You’d multiply 232 weeks by 10%, which equals 23.2 weeks of benefits. You then multiply that figure by your weekly compensation rate to reach your total payout.

Keep in mind that Missouri caps the weekly rate. Even if two-thirds of your wage is high, the state maximum limits how much you can collect per week.

What Should You Do If You Disagree With Your PPD Rating?

Insurance company doctors often assign lower ratings than independent doctors do. A lower percentage means a smaller payout, which benefits the insurer, not you.

If the offered rating feels too low, you don’t have to accept it. Consider these steps:

  • Get a second opinion. An independent medical evaluation may produce a higher, more accurate rating.
  • Consult an attorney. A workers’ compensation attorney can review your case, challenge an unfair rating, and help you pursue full disability compensation.

Disputing a rating can meaningfully change the amount you receive, so it’s worth taking seriously.

Frequently Asked Questions

What Does a Permanent Partial Disability Rating Mean in Missouri?

It’s a percentage a doctor assigns to reflect the permanent loss of use of an injured body part after a work-related injury. The worker still has some ability to work, which separates a partial rating from a total disability finding.

When Is a PPD Rating Assigned?

A doctor assigns a PPD rating only after the injured worker reaches Maximum Medical Improvement (MMI), the point where the condition has stopped improving with treatment.

How Is PPD Compensation Calculated in Missouri?

Missouri multiplies three figures: statutory weeks for the body part, the disability percentage, and the weekly compensation rate. The weekly rate equals two-thirds (66.67%) of your average weekly wage, subject to state maximum limits.

What Is the Difference Between Scheduled and Non-Scheduled Injuries?

Scheduled injuries affect specific body parts with set week limits, such as 232 weeks for an arm. Non-scheduled injuries affect the body as a whole and carry a 400-week maximum.

Can I Dispute a PPD Rating I Think Is Too Low?

Yes. Insurance company doctors often give lower ratings than independent doctors. You can seek a second opinion and consult an attorney to challenge the rating and pursue fair disability compensation.
