However, a plaintiff who claims "serious injury" must offer some reasonable explanation for an extended gap in treatment or cessation of treatment (Id.). This Court has not considered the defendants' contention regarding a gap in treatment, as it was improperly raised for the first time in their reply papers (Carrier v Gleba, 213 A.D.3d 629, 630 [2d Dep't 2023] citing Diaz-Montez v JEA Bus Co., Inc., 175 A.D.3d 1384, 1386 [2d Dep't 2019]; Davis-Hassan v Siad, 101 A.D.3d 932, 933, [2d Dep't 2012]). In any case plaintiff explains she stopped treatment because she was pregnant.
