A Spokane dermatologist has wrung a $600,000 apology from state health officials who went public with outrageous charges of drug abuse and medical fraud based on a bogus tip from his ex-wife. The pending payout to Dr. William “Phil” Werschler is among the largest settlements in decades by the Washington state Department of Health involving a physician, agency officials say. The public apology might be the first of its kind, they say.
