NEW YORK (CBSNewYork/AP) – Former New York City Mayor Ed Koch is improving but remains hospitalized, spokesman George Arzt said on Wednesday.
Arzt added that it remains unclear when the 88-year-old Koch could be released from NewYork-Presbyterian/Columbia hospital.
The former mayor was readmitted to the hospital on Monday with fluid build-up in his ankles and lungs, two days after he was released. Koch was first hospitalized for water in his lungs and legs on Jan. 19.
Doctors have been working to reduce the fluid, according to Arzt, who also said Koch has an iron deficiency.
On Tuesday night, a new documentary about Koch’s career premiered at the Museum of Modern Art.
Arzt says Koch asked about how many people attended, and who they were.
The three-term mayor has had previous health issues, including a stroke, a heart attack and quadruple bypass surgery.
Koch served as mayor from 1978 to 1989.
