The shooter was identified as Dr. Henry Bello, two law enforcement officials told CNN.
The suspect has been identified as a former family physician at the hospital where he went on the rampage.
The officials were not authorised to discuss the still-unfolding investigation and spoke on condition of anonymity.
Mayor Bill de Blasio said several doctors were "fighting for their lives" following the incident in the Bronx borough north of Manhattan.
Ultimately, one female doctor was killed and six others wounded - five seriously, according to Police Commissioner James O'Neill.
Two law enforcement officials say the doctor who opened fire at a New York City hospital where he once worked was allowed to resign in 2015 amid sexual harassment allegations.
By the time police found Bello on the 17th floor, he was dead of a self-inflicted gunshot wound, O'Neill said.
The gunman, who was wearing a white lab coat and had ID on him, shot himself on the 16th floor, according to law enforcement officials.
At least one doctor was treated inside the hospital by people who had tied an emergency fire hose as a tourniquet, a fire department official told the New York Times. It was not immediately clear whether police were looking for any other suspects.
The Bronx-Lebanon Hospital Centre is one of the largest health care facilities in the Bronx, and New York City as well.
She said: "What do you do when you hospital has shooter in it", later adding: "Nice start of the weekend".
Francisco Bodon, a patient at Bronx Lebanon, tells NBC New York sister station Telemundo 47 that he was in a room on the 10th floor when three gunshots rang out and then chaos erupted.
Maya said they were eventually led out of the hospital as they followed a group of nurses. Two confirmed shot. Man dressed all in black. Special agents with the New York Bureau of Alcohol, Tobacco, Firearms, and Explosives were also responding to the incident at the hospital, the bureau tweeted. Police could be seen on the roof of the building, at one point, with their guns drawn.
According to ABC7NY, gunfire was reported at the Bronx Lebanon Hospital Center around 3 p.m. local time. Its emergency room is among the busiest in New York City.
Police had no immediate information on whether anyone was killed.
