Hm that is interesting, i do show that 40810-40816 are currently active/valid CPT codes....
40812 stands for: Excision of lesion of mucosa and submucosa, vestibule of mouth; with simple repair
4110-41114 are as follows:
41110 - Excision of lesion of tongue without closure

41113 - Excision of lesion of tongue with closure; posterior one-third
