skin biopsy

What is the difference between codes 11100 nad 11300. CPT says 11300 can be a punch 11100 not inclusive of punch biopsy?

11100 is for a separate biopsy. Often, the physician takes the punch biopsy to fully remove a lesion. He still sends the specimen for pathology (hence we think a biopsy as in 11100) but in these cases 11100 is considered part of 11300.

OK so if the biopsy is not taking the full lesions then we should code 11100. In this case part of lesions were left until path report came back. Is this correct?

yes. When the doctor is doing only a biopsy and then waiting for the report to decide whether to remove the lesion, then you code the biopsy. If the patient has to come back in after the report and then have the lesion removed, you would then code the removal, punch, shave, etc, as appropriate.
