Lenox Hill Ortho program is modifying its handling of Acting Internship / Away rotations for the 2026-2027 application cycle due to a number of factors. Initial efforts to align regular decision applications to the AOA/CORD schedule have not been successful. Announcements for remaining rotation positions for all 2026 dates will be released on Universal Offer Day 4/13 Noon EST, followed by rolling offers, with each offer carrying a 24 hour expiration.

We apologize for any confusion this may have caused applicants during this cycle. An announcement to all applicants will follow when there are no open blocks remaining.

All current Early Decision / VSLO Confirmed Rotations are verified and may disregard above message.
