Apparently yes, according to this malpractice lawsuit:
In a unanimous opinion last April, however, the Texas Supreme Court overruled that decision and upheld the trial verdict. While most patients might not be expected to volunteer where the pain began, a physician-patient like Axelrad would be under a greater obligation to report such information, even if the treating doctor didn’t specifically ask about it. Since a jury “must consider a physician’s special knowledge when a doctor is the defendant,” the court held, “it is hard to see why they should not do so when a doctor is the plaintiff.”
