In Washington, 5-10 cents on the dollar may not be reasonable. Moreover, just because a lawyer asks the Chiropractor to reduce his bills, that doesn't mean the chiropractor will agree to do so. Suggesting such a reduction in bills puts the reader in a position of potentially unreasonable expectations.

It might be reasonable to suggest negotiating the outstanding bills, but giving a percentage like 5% could be misleading.

There are other areas that have potential for negotiations, such as with the PIP carrier, Health Insurance carrier, etc. And of course, although we don't like to entertain it, attorneys' fees and costs are often negotiable.
