Do regular molar extractions cost the same as wisdom tooth extractions?

I recently had all 4 of my wisdom teeth removed by an oral surgeon plus a regular molar on the top right that was damaged by the wisdom tooth. They charged me the same amount to remove that tooth as they did for the wisdom teeth. On my insurance claim form the procedure was described as "Surgical removal of erupted tooth requiring elevation of mucoperiosteal flap and removal of bone and/or section of tooth" I just wanted an opinion from anyone in the dentistry field before I call them up with accusations of overcharging me.
