I have a group of urologists that have started out on their own. They do a lot of cystoscopies with vaginoscopies when there is some undetermined vaginal bleeding. They do NOT use a colposcope to do the vaginoscopy. There is no actual CPT code that I can find for a vaginoscopy. Can the 57420 be used to bill out a vaginoscopy even if the Dr. does not utilize the colposcope?
They also do pediatric vaginoscopies for the same reason sometimes. Would it be billed as 57420 also?

Any help and guidance would be greatly appreciated!
