This seems to be quite a long series of messages via text and phone calls. The female patient told his wife and the patient had threatened suicide if he stopped. The doctor is 65 and the patient is 26. 
Strangely enough the doctor treated patients for drug and alcohol addictions and the article also said he had stopped seeing the patient before the phone sex began. Eventually they met in person but never did commit the the act but lot of petting and other items were mentioned here. BD
ALBANY - A Long Island doctor who treated patients with drug addictions got hooked on having phone sex with one - and later told his wife, state health officials say.
A Health Department disciplinary committee found that Dr. Michael Eisenberg, 65, engaged in an "abusive," two-year relationship with a woman sent to him for treatment for alcohol abuse.
The panel declared him morally unfit to practice medicine and stripped him of his license.
"The overwhelming evidence in this case clearly establishes that Dr. Eisenberg engaged in a sexual relationship with a very ill patient and that this act did her harm," the panel said in a report.
Investigators said Eisenberg and the patient - who was 26 when she first saw Eisenberg - exchanged nearly 2,200 "personal and or sexual telephone calls" and approximately 12,000 text messages from January 2007 through September 2009.
