Understanding AMA Guides 5th Edition
The AMA Guides to the Evaluation of Permanent Impairment, 5th Edition, is the standard reference used in most workers' compensation jurisdictions for rating permanent impairment.
Key Components of Spine Impairment Rating
- Diagnosis-Related Estimate (DRE): Categories I through V based on severity of pathology and surgical intervention
- Range of Motion (ROM): Measured in degrees for each plane of motion when DRE doesn't apply
- Radiculopathy: Additional impairment for nerve root compression with objective findings
- Neurological deficits: Motor, sensory, or reflex loss adds to overall rating
Common Impairment Ranges
- Simple discectomy (successful): Typically 5-8% whole person impairment
- Single-level fusion: Typically 10-13% whole person impairment
- Multi-level fusion: 15-25% depending on levels and neurological involvement
- With radiculopathy: Additional 5-10% depending on severity
These are general ranges; actual ratings depend on specific clinical findings and methodology used.
What Is Evaluated
Neutral, Defensible Opinions
Evidence-Based Methodology: All opinions are grounded in objective clinical findings, peer-reviewed literature, and established medical guidelines—not advocacy.
Equal Treatment: Whether representing plaintiff or defense, each case receives the same rigorous, unbiased analysis focused solely on the medical facts.
Deposition-Ready: Reports are written to withstand scrutiny, with clear rationale and supporting medical evidence for every conclusion.

- Complete medical records documenting the condition
- All spine imaging (MRI, CT, X-rays) with radiology reports
- Surgical reports if applicable
- Physical therapy records showing functional limitations
