1. What is the AMA Guides Combined Values Equation?

The AMA Guides Combined Values Equation calculates the combined effect of multiple impairment values according to the American Medical Association guidelines. This method provides a systematic approach to combine multiple disability ratings into a single comprehensive value.

2. How Does the Calculator Work?

The calculator uses the AMA Guides Combined Values Equation:

Where:

• \( A \) — First impairment value (unitless, 0-1)
• \( B \) — Second impairment value (unitless, 0-1)

Explanation: The equation accounts for the non-additive nature of multiple impairments by considering the remaining capacity after the first impairment is applied.

3. Importance of Combined Values Calculation

Details: Accurate combined values calculation is crucial for disability assessments, workers' compensation cases, and determining appropriate compensation levels for multiple impairments.

4. Using the Calculator

Tips: Enter impairment values A and B as decimal numbers between 0 and 1. Both values must be valid (0 ≤ value ≤ 1).

5. Frequently Asked Questions (FAQ)

Q1: Why use the AMA Guides Combined Values method?
A: This method provides a standardized approach recognized by medical and legal professionals for combining multiple impairment ratings in disability assessments.

Q2: What do the input values represent?
A: Input values represent impairment percentages expressed as decimals (e.g., 0.25 = 25% impairment).

Q3: How are more than two impairments combined?
A: For multiple impairments, combine the first two values, then combine the result with the third value, and so on sequentially.

Q4: Are there limitations to this equation?
A: The equation assumes impairments are independent and may not account for synergistic effects between certain conditions.

Q5: Is this method used internationally?
A: While primarily used in the United States, the AMA Guides methodology is recognized and referenced in many countries for disability assessment.
