A vaginoscope is not the same this as a colopscope (and the cost for the vaginoscope is usually much less) so you are correct there is no colpo code that would fit this scenario for the removal of the cervical polyp. And I agree that the only reason to use the vaginosope was to be able to insert the hysteroscope so it would not be coded separately, but if time had been included as part of the op note to indicate how much longer it took to perform this procedure you might qualify for a modifier -22. The clinical vignette for 58558 includes an examination of the endocervical canal for lesions. Although the code does not go on to mention a cervical lesion in addition to possible endometrial lesions being sampled or removed, the interpretation by the payer could go with way. If you do not have a confirmed fibroid, your only choice for the lesions removal inside the uterus is 58558. You would not add a modifier -52 in this case because one lesion was removed and there is no requirement that more than one or even a complete lesion be removed to use this code. As to the cervical polyp, there is no code specific to removal via a hysteroscope so your only option is to bill 57500 as a additional code and see what happens. If you decided to try using a modifier -22, on the other hand, you would not bill separately for the cervical lesion, but count it as part of the additional significant work. The payer, of course, will have have last word on this.
