<h2>What Is Combined Disability?</h2>
<p>When a person suffers from more than one medical condition, the National Insurance Institute (ביטוח לאומי) does not simply add the disability percentages together. Instead, it applies a <strong>staggered (combined) calculation</strong> that always results in a total lower than the arithmetic sum. Understanding this method is critical for anyone expecting their disability level to reflect multiple injuries.</p>
<h2>The Staggered Calculation Method</h2>
<p>The formula works as follows: the highest disability percentage is applied first to 100% of the “healthy” body. The next disability percentage is then applied to the remaining (non-disabled) portion, and so on.</p>
<h3>Example: 50% + 30%</h3>
<ol>
<li>First impairment: 50% of 100 = 50% disabled, leaving 50% healthy</li>
<li>Second impairment: 30% of the remaining 50 = 15% additional disability</li>
<li><strong>Combined total: 65%</strong> — not 80% as a simple addition would suggest</li>
</ol>
<h2>Order of Disability Percentages Matters</h2>
<p>The order in which disabilities are presented to the committee can affect the outcome. Presenting the higher percentage first maximizes the combined result. An experienced attorney ensures the most favourable presentation order.</p>
<h2>Which Injuries Are Excluded?</h2>
<p>Not all medical conditions are included in the combined calculation. Certain injuries or diseases that fall outside the recognized list of the National Insurance Institute’s medical regulations are excluded. This is a common source of errors in committee decisions.</p>
<h2>Common Errors in Committee Calculations</h2>
<ul>
<li>Applying the wrong percentage to a specific injury</li>
<li>Omitting a recognized medical condition from the combination</li>
<li>Incorrect ordering of disability percentages</li>
<li>Arithmetic errors in the staggered formula</li>
</ul>
<p>An attorney can review the committee’s calculation and challenge any error — even a small percentage point difference can translate into tens of thousands of shekels over time.</p>
<h2>How to Prepare for the Medical Committee</h2>
<ul>
<li>Document every recognized condition with recent medical reports</li>
<li>Bring specialist letters that quantify the disability level for each condition</li>
<li>Arrive with a clear list of all conditions to be presented</li>
<li>Consult an attorney before the committee to optimize the presentation order</li>
</ul>
