The only transcripts you are required to submit are for college courses, and these go to AACOMAS, not to NYCOM or any other osteopathic school directly.
The only reason I could think of where NYCOM would require you to send a HS transcript would be for their BS/DO program, and even then you'd primarily be going through NYIT and not NYCOM.
Hope this helps.
