To hear Health Plan of Nevada's advocates tell it, Dr. Dipak Desai was a master of deception. He was a real sleight-of-hand artist, a veritable David Copperfield of the colonoscopy. The fact Desai and a nurse anesthetist are on trial facing a list of criminal charges including second-degree murder illustrates the fact he's the one at fault. HPN, on the other hand, is a dedicated and charitable servant of nearly 500,000 Nevadans' health care needs. Its reputation has been besmirched by last month's staggering $500 million punitive damage award for its role in the hepatitis C outbreak at Desai's now-closed Endoscopy Center of Southern Nevada.
