... as there was a very similar episode of Quincy in season five.
Dr. Stanley Royce (Jose Ferrer) loses a patient while performing heart surgery on him. Royce at first convincingly argues that the patient died because of calcium in the arteries. But then Quincy finds out that an old technique was used on the dead patient when Royce had perfected a more modern technique that would likely have saved the patient. So Quincy comes to believe that Royce is performing "ghost surgery" - letting residents finish up operations, maybe when Royce isn't even in the OR to supervise so that Royce can do multiple procedures. Royce denies the accusation, but Quincy continues to dig.
This was one of those "issue" episodes that made the last season of Quincy so tiresome. There's no mystery here - You hear Royce discussing with hospital officials that he is indeed doing what Quincy says he is doing, and it's not illegal. Without a mystery and without what most people think of as a traditional crime, this episode just misses the mark.
I give it 6/10 rather than 5/10 for the presence of Jose Ferrer as the surgeon.
