Understanding Permanent Disability Ratings: What They Mean for Your Benefits

Law Office of Olivia Devonmille, P.A. May 29, 2025

When a worker in Florida suffers an injury that results in lasting physical impairment, the workers’ compensation system uses a Permanent Disability Rating (PDR) to help determine the level of benefits available. The PDR process can significantly impact a worker’s financial future, particularly when the injury permanently affects their ability to earn a living. 

For those depending on workers’ compensation benefits, knowing how the rating system functions is critical to securing the financial support they deserve after a life-altering injury. At the Law Office of Olivia Devonmille, P.A. I help clients in Vero Beach, Florida, better grasp their rights and benefits when dealing with disability.

What Is a Permanent Disability Rating?

A Permanent Disability Rating is a percentage that reflects the extent of a worker’s permanent impairment following a workplace injury. After reaching what doctors call Maximum Medical Improvement (MMI), meaning further recovery isn’t expected even with continued medical care, an evaluation takes place. 

A qualified physician assesses the lasting effects of the injury and assigns a rating. This percentage plays a major role in deciding the amount and duration of workers’ compensation benefits an injured worker will receive in Florida.

In Florida, this rating not only determines eligibility for permanent impairment benefits but can also influence settlement discussions and future employment options. Since workers’ compensation laws vary from state to state, understanding Florida’s approach is important for anyone who suffers a workplace injury in this state.

How Permanent Disability Ratings Are Calculated

In Florida, the calculation of a Permanent Disability Rating typically follows the guidelines outlined in the Florida Uniform Permanent Impairment Rating Schedule. Physicians trained in evaluating permanent impairments rely on this schedule to maintain consistency across cases.

Several factors contribute to a PDR:

  • Medical evidence: Objective tests, medical imaging, and documented clinical evaluations

  • Type of injury: Different injuries affect people in varying ways, and some body parts are rated differently depending on how critical they are to general physical function

  • Extent of functional loss: How the injury limits daily activities or work tasks

  • Occupational impact: Although not directly part of the rating, the effect on future job prospects often enters later stages of workers’ compensation benefit discussions

Florida requires that only licensed doctors familiar with the impairment rating system perform these evaluations. Once assigned, the Permanent Disability Rating becomes a key figure in calculating permanent impairment benefits.

Why Permanent Disability Ratings Matter

The Permanent Disability Rating has a direct effect on the benefits a worker can receive. In Florida’s workers’ compensation system, the percentage assigned reflects the severity of the injury and helps determine the amount of money and length of time benefits are paid.

Ratings also often influence settlement negotiations if an injured worker and employer’s insurance company decide to resolve the claim through a lump-sum settlement.

Missing work due to injury not only creates immediate financial hardship but can also lead to long-term economic instability. Workers’ compensation benefits based on accurate Permanent Disability Ratings are critical to bridging that gap and providing financial support over the long term.

What Is Maximum Medical Improvement?

Maximum Medical Improvement (MMI) plays a central role in determining a Permanent Disability Rating. Before a physician can assign a rating, the injured worker must reach MMI. This designation means the worker's medical condition has stabilized and further significant improvement is unlikely.

Once MMI is reached, the treating doctor evaluates the worker’s lasting impairments and assigns the rating based on established guidelines. MMI does not mean the worker has fully recovered; rather, it means that their condition is as good as it is likely to get. 

Workers’ compensation benefits related to temporary disability typically end when MMI is reached, making the transition to permanent impairment benefits crucial.

Because the shift from temporary to permanent benefits hinges on MMI and the subsequent rating, workers need to be prepared for this transition and understand how it affects their financial outlook.

Permanent Partial vs. Permanent Total Disability

Florida workers’ compensation law recognizes two types of permanent disability: Permanent Partial Disability (PPD) and Permanent Total Disability (PTD).

  • Permanent Partial Disability: Applies when the worker retains some ability to work but has a lasting impairment. Benefits are calculated based on the assigned disability rating and the worker’s pre-injury wage.

  • Permanent Total Disability: Applies when the injury prevents any meaningful employment. Workers in this category may be eligible for benefits for the rest of their lives, depending on the injury and other circumstances.

The majority of injured workers who qualify for permanent benefits fall under the PPD category. Only the most severe injuries, such as catastrophic brain injuries, paralysis, or total blindness, generally result in a PTD classification under Florida’s workers’ compensation system.

How Benefits Are Calculated Based on the Rating

Once a Permanent Disability Rating is assigned, it is used to calculate benefits under the Florida workers’ compensation statutes. Permanent impairment benefits are generally paid at a rate of 75% of the worker’s Temporary Total Disability (TTD) rate, subject to reductions for any earnings or earning capacity.

For example, if a worker’s TTD rate was $500 per week, their permanent impairment benefits would typically be $375 per week. The duration of payments depends on the percentage assigned:

  • 1% to 10% impairment: 2 weeks per percentage point

  • 11% to 15% impairment: 3 weeks per percentage point

  • 16% to 20% impairment: 4 weeks per percentage point

  • 21% and higher: 6 weeks per percentage point

This tiered approach means that higher disability ratings result not only in higher payments but also longer periods of compensation.

Disputing a Permanent Disability Rating

Disagreements over Permanent Disability Ratings can occur. A worker might feel that the assigned rating does not accurately reflect their level of impairment. Florida workers’ compensation law provides mechanisms to dispute a rating.

An injured worker may request an Independent Medical Examination (IME) from a different doctor. This second opinion can be presented as evidence during any hearings or negotiations over workers’ compensation benefits. If disagreement persists, the matter can be brought before a Judge of Compensation Claims, who will evaluate the evidence and issue a ruling.

Workers facing disputes must be aware of deadlines and procedural rules when challenging a rating, as missing these steps can jeopardize their benefits.

Settlement Considerations Related to Permanent Disability Ratings

Many workers’ compensation cases in Florida are resolved through settlements rather than prolonged court proceedings. A worker’s Permanent Disability Rating often plays a central role during settlement negotiations.

Insurance companies use the PDR as a starting point to calculate the lump-sum value of a case. A higher rating typically results in a larger settlement offer. However, other factors, such as future medical costs, vocational rehabilitation needs, and the worker’s age and career prospects, can also influence the final settlement figure.

Workers should carefully review any settlement offers to determine whether the amount fairly compensates for both the impairment and potential future challenges arising from the injury.

Tips for Protecting Your Rights After Receiving a Permanent Disability Rating

Workers injured on the job in Florida can take steps to protect their rights and maximize their benefits:

  • Stay informed: Learn about Florida workers’ compensation laws and how PDRs affect benefits.

  • Request copies: Obtain and keep copies of all medical evaluations, including the doctor’s written Permanent Disability Rating.

  • Act promptly: Respond quickly if you disagree with a rating to avoid missing important deadlines.

  • Document everything: Keep detailed records of how the injury impacts daily life and work activities.

  • Review settlement offers carefully: Before accepting a lump-sum settlement, fully assess the long-term financial implications.

  • Consider getting an Independent Medical Examination: If there is reason to believe the initial rating is inaccurate, a second opinion can be crucial.

Taking these steps can help injured workers receive the compensation they’re entitled to under Florida’s workers’ compensation system.

How Florida’s Workers’ Compensation System Differs

It’s important to recognize that Florida’s approach to workers’ compensation isn’t identical to other states. Florida places specific caps on benefits and requires strict adherence to timelines. For instance, the maximum number of weeks for impairment income benefits depends closely on the assigned rating, with little flexibility once the rating is finalized.

Florida also imposes tight deadlines for filing claims and challenging decisions. Missing these deadlines can severely limit available benefits, no matter how serious the injury. Therefore, workers need to remain proactive and attentive once they receive a Permanent Disability Rating.
