The problem is because the .expandable elements are li which cannot have the disabled attribute. Use a class on them instead, and use that in the :not selector:

$('.expandable-panel').find('.expandable').each(function() {
  if (!$(this).is('.disabled')) {
    $(this).find('.expand-title').click(function() {
      $(this).parent().toggleClass('expanded');
    });
  }
});
.expandable-panel {
  padding: 0;
  margin: 0;
  list-style: none;
}

li.disabled {
  background: red;
}

.expandable-panel > li {
  border: 1px solid #c7d0d8;
  border-radius: 3px;
  background: #ffffff;
  margin-bottom: 10px;
}
.expandable-panel > li.disabled {
  pointer-events: none;
}

.expandable-panel > li .expand-title {
  background: none;
  font-weight: normal;
  width: 100%;
  text-align: left;
  position: relative;
  padding-right: 36px;
}

.expandable-panel > li .expand-title:after {
  position: absolute;
  right: 16px;
  top: 14px;
  border: 5px transparent solid;
  content: ' ';
  border-top-color: #669BC6;
}

.expandable-panel > li:hover {
  border-color: #99A6B5;
}

.expandable-panel > li:hover .expand-title:after {
  border-top-color: #136FD5;
}

.expandable-panel > li .panel-content {
  visibility: hidden;
  opacity: 0;
  height: 0;
  transition: all 0.3s ease;
}

.expandable-panel > li .panel-content > .content {
  padding: 1.2em;
}

.expandable-panel .expanded {
  border: 1px solid #99A6B5;
}

.expandable-panel .expanded .panel-content {
  visibility: visible;
  opacity: 1;
  height: auto;
}

.expandable-panel .expanded .expand-title {
  border-bottom: 1px solid #99A6B5;
  border-radius: 3px 3px 0 0;
}

.expandable-panel .expanded .expand-title:after {
  top: 8px;
  border: 5px transparent solid;
  content: ' ';
  border-bottom-color: #669BC6;
}

.expandable-panel .expanded:hover .expand-title:after {
  border-top-color: transparent;
}

                  <input type="radio" id="default" name="radio" value="Default">
                  <label for="default">Item to Select</label>
                </li>
                <li>
                  <input type="radio" id="selected" name="radio" value="Selected" checked>
                  <label for="selected">Selected Item</label>
                </li>
                <li>
                  <input type="radio" id="disabled" name="radio" value="Disable">
                  <label for="disabled">Item to Select</label>
                </li>
              </ul>
            </li>
          </ul>
        </form>
      </div>
    </div>
  </li>
</ul>

Also note that I set pointer-events: none on the disabled .expandable so that the click isn't even registered in the UI.
