Permanent Partial Disability (PPD)
Benefits in Nevada

What Is Permanent Partial Disability in Nevada?

Permanent partial disability is a workers' compensation benefit that compensates an injured worker for lasting physical impairment that remains after maximum medical improvement. The word "partial" is the critical distinction: PPD applies when the injury has caused permanent damage, but the worker retains some capacity for gainful employment. If no such capacity remains, the worker may qualify for permanent total disability (PTD) instead.

​

PPD does not compensate for your inability to perform your specific pre-injury job. It compensates for the objective, measurable reduction in your physical function, what Nevada law calls "whole person impairment", regardless of your occupation. A back injury that produces a 15% whole person impairment rating produces the same rating for a construction worker and an office worker. What differs is the monthly benefit amount, because it is tied to each worker's individual average monthly wage.

When Does PPD Begin?

PPD benefits begin after you reach maximum medical improvement (MMI), defined under NRS 616A.065 as the point at which your medical condition has stabilized and further treatment is not expected to produce significant improvement. Your treating physician signals this by noting you are "stable and ratable" in your medical records, which triggers the insurer's obligation to schedule a formal impairment evaluation within 30 days.

​

It is worth understanding that MMI does not mean you have fully recovered. It means your condition has reached a plateau. Many PPD recipients continue to experience symptoms and require ongoing medical treatment, coverage for which continues under the claim even after PPD benefits begin.

How PPD Ratings Are Determined in Nevada

Nevada uses a structured, standardized system for determining PPD impairment percentages. The rating process is governed by specific statutory requirements that protect both workers and insurers from arbitrary evaluations.

​

The AMA Guides, Fifth Edition: Nevada's Mandated Standard

Under NRS 616C.110, Nevada requires the use of the American Medical Association's Guides to the Evaluation of Permanent Impairment, Fifth Edition, for all PPD ratings. While most states have moved to the Sixth Edition, Nevada has retained the Fifth Edition because stakeholders determined it produces fairer compensation for seriously injured workers. This matters in practice: the two editions use different methodologies that can produce meaningfully different impairment percentages for the same injury.

Who Performs the Evaluation

Only physicians and chiropractors on the Nevada Division of Industrial Relations approved rating list are authorized to perform PPD evaluations. The insurer schedules the evaluation and selects the physician from this list. The rating physician performs an objective examination and reviews your medical records to calculate a whole person impairment percentage under the AMA Guides. This percentage forms the foundation of your entire PPD benefit.

Your Right to a Second Opinion

If you disagree with the impairment rating assigned by the insurer's chosen physician, you have the right to request a second evaluation. The DIR assigns the next physician on its approved list to conduct an independent evaluation. If the two ratings differ, the claim may proceed to a hearing where the evidence is weighed. You may also request a third evaluation under certain circumstances.

​

Knowing when to exercise this right, and how to prepare for a second evaluation, is one area where legal guidance makes a concrete, quantifiable difference in outcomes.

What the Rating Physician Assesses

The rating physician examines objective medical findings to assign a whole person impairment percentage. Key factors include:

​

• Range of motion measurements for the affected body part or spinal region

• Neurological deficits, nerve damage, weakness, sensory loss

• Diagnostic imaging findings, MRI, CT, and X-ray results correlating to objective impairment

• Surgical history and outcomes, including the residual effects of procedures performed during treatment

• For spinal injuries: activities of daily living (ADL) adjustments, which may add 1 to 3 percentage points to the rating

KEY: What the rating physician cannot consider.

Nevada law limits the PPD rating to objective physical impairment only.

The physician may not factor in your occupation, earning capacity, difficulty finding work, or subjective pain levels beyond what the AMA Guides methodology accounts for.

This limitation cuts both ways: it prevents inflated ratings based on job loss, but it also means a very physically demanding job that is now impossible does not increase your percentage, even if your practical loss is enormous. Understanding this distinction is important when evaluating your overall claim strategy.
