question on defining one or 2 surgeries

In april of last year I was sent by the VA to have surgery for severe cervical spinal stenosis, I had bulging discs at the C5,C6,C7 levels as well as osteophytes that were abutting and deforming the spinal cord. The original plan was an ACDF at those levels and this was done on the 27th of April. The 29th it was decided that the ACDF had not decompressed the cord enough so a laminectomy was performed at the C6,C7 level. My question is are these considered 2 separate surgeries since only the ACDF had been planned? Or are they considered one due to both being done during the same hospital stay? I know it seems a silly question to some but it could make a difference in some issues of my life. Thank you to anyone who can answer this for me.

As long as the procedures was done in the same operating room at the same time, this is considered "one operation". If the surgeries were performed on different dates then there are "two operations".
