DiLorenzo v Zaso, 2017 NY Slip Op 02402 (2d Dept. 2017)
“[A] medical expert need not be a specialist in a particular field in order to testify regarding accepted practices in that field” (Behar v Cohen, 21 AD3d 1045, 1046-1047 [internal quotation marks omitted]). However, the witness must “be possessed of the requisite skill, training, education, knowledge or experience from which it can be assumed that the opinion rendered is reliable” (id. at 1047 [internal quotation marks omitted]). “Thus, where a physician opines outside his or her area of specialization, a foundation must be laid tending to support the reliability of the opinion rendered” (id.). Where no such foundation is laid, the expert’s opinion is “of no probative value” (Feuer v Ng, 136 AD3d at 707; see Tsimbler v Fell, 123 AD3d 1009, 1009-1010; Shashi v South Nassau Communities Hosp., 104 AD3d at 839; Geffner v North Shore Univ. Hosp., 57 AD3d at 842; Mustello v Berg, 44 AD3d 1018, 1018-1019).”
