After three hours behind closed doors, Dr. Mark G. Midei made no comment as he emerged from a state office building in Northwest Baltimore. His lawyer, Stephen Snyder, described the talks as confidential and said, "I can't divulge to you the results of the hearing."
C. Irving Pinder, Jr., executive director of the board, did not respond to messages Wednesday.
The board, which licenses doctors in Maryland, charged Midei in June with "gross overutilization of health care services" and "willfully making a false report or record in the practice of medicine." Midei could be fined and lose his medical license if the charges are upheld.
Wednesday's meeting was a "case resolution conference" that in some instances has been used to hammer out a settlement.
Midei, 53, ran the cardiac catheterization lab at St. Joseph Medical Center in Towson until last year and is alleged to have put stents in the arteries of patients who did not need them. He is also accused of falsifying medical records to make it appear patients met criteria for the costly procedure.
St. Joseph has informed 585 of Midei's patients that their stent procedures might have been unwarranted, exposing them to the risk of fatal blood clots and side effects from blood-thinning drugs. The hospital reviewed 2,000 of his cases and revoked his hospital privileges last year.
Midei has said that he expects to be exonerated.
