⚖️ What Is Permanent Partial Disability (PPD)?
Permanent Partial Disability refers to a situation where your work injury permanently impairs part of your body or limits your ability to work. However, you are still able to do some work.
Unlike Permanent Total Disability (PTD)—which means you can’t work at all—PPD compensates you for the permanent damage, even if you return to your job.
Examples of Injuries That May Qualify as PPD:
- A torn rotator cuff that limits shoulder mobility
- Carpal tunnel syndrome causes chronic wrist pain
- Back injuries with ongoing stiffness or limited motion
- Knee injuries resulting in difficulty climbing stairs
- Hearing or vision loss affecting only one ear or eye
- Fractures that don’t fully heal or restrict movement
If your injury results in a permanent loss of function, even partially, you may be entitled to PPD compensation under Missouri law.
🏥 The Role of Maximum Medical Improvement (MMI)
Before PPD benefits can be determined, your treating physician must declare you’ve reached Maximum Medical Improvement (MMI). This means your condition is as good as it’s going to get—further treatment won’t improve it.
Once MMI is reached:
- The doctor assigns a permanent disability rating
- That rating determines your PPD compensation
- You can dispute the rating with a second opinion (and you should, if it’s too low)
⚠️ Many injured workers receive lowball ratings from insurance doctors. It’s critical to consult with a workers’ comp attorney who can fight for a fair impairment rating and negotiate a stronger settlement.
📊 How Is PPD Compensation Calculated in Missouri?
Missouri uses a standard formula to calculate PPD benefits:
🧮 PPD Formula:
(Level of disability %) x (Number of weeks assigned to the body part) x (Comp rate)
Let’s break that down:
- Level of disability (%): The percentage of your body part that is permanently impaired
- Weeks assigned: Missouri’s schedule assigns a number of weeks to each body part
- Compensation rate: Two-thirds of your average weekly wage (up to a state max)
🧑💼 PPD Settlement Options: Lump Sum vs Weekly
Once your PPD value is determined, you may receive benefits in two ways:
- Lump Sum Settlement (Stipulation Agreement) 💰
- You agree to a total amount and waive future claims
- Fastest route to close your claim, but may limit future benefits
- Weekly Payments (Award) 📆
- You receive payments over time
- Keeps your case open to possible future benefits
💡 Tip: A lump sum can be convenient—but only if you’re confident your injury won’t worsen. An experienced attorney can negotiate higher payouts and ensure medical care is still available.
🚨 Disputes Over PPD Ratings and Benefits
It’s common for insurance companies to downplay your injury or push for a lower disability rating. They may use their doctor to minimize costs.
Common disputes include:
- Low impairment percentage
- Wrong body part classification (e.g., wrist vs. whole arm)
- Miscalculated weekly wages
- Denied treatment that affects your rating
