Understanding DVA Permanent Impairment (PI) Points
The Department of Veterans' Affairs (DVA) uses a specific methodology to calculate compensation for Permanent Impairment (PI). Unlike standard addition, impairment points are calculated using the "Combined Values Chart" principle. This ensures that the total impairment rating reflects the "Whole Person Impairment" (WPI) and never exceeds 100%.
How the Calculation Works
If you have multiple accepted conditions, the DVA does not simply add the points together (e.g., 20 points + 20 points does not equal 40 points). Instead, they use a formula that combines the effects of multiple injuries on your overall health.
The standard formula used for combining two values is:
Combined Impairment = A + [B × (100 – A) / 100]
Where A is the current highest impairment rating, and B is the next rating to be combined.
Example Calculation
Consider a veteran with three accepted conditions rated at 40 points, 20 points, and 10 points.
Step 1: Start with the highest rating: 40.
Step 2: Combine with the next highest (20). The remaining "whole person" is 60% (100 – 40). We take 20% of that remaining 60%, which is 12. So, 40 + 12 = 52.
Step 3: Combine the new total (52) with the final rating (10). The remaining "whole person" is 48% (100 – 52). We take 10% of 48%, which is 4.8. So, 52 + 4.8 = 56.8.
Final Step: Round the result to the nearest whole number. The final PI score is 57 points.
Why This Matters
Your PI score determines the level of compensation you are eligible for under acts like the MRCA (Military Rehabilitation and Compensation Act) and DRCA (Safety, Rehabilitation and Compensation (Defence-related Claims) Act). Thresholds for Gold Cards or lump sum payments rely heavily on accurate point calculations.
