Diagnosis code
Hi,
I think the reason for the procedure would determine the correct code. IF the reason for the procedure was "removal of the lesion" then 11300 would be appropriate, biopsy (11100) would not be reported separately. On the other hand, the reason for the procedure was to obtain the tissue to be sent to path, 11100 would be appropriate, shaving (11300) would not be reported separately. I hope this would help.
Please find below the coding guideline on Biopsy as given in ICD - 9 - CM Manual:
"During certain surgical procedures in the integumentary system, such as excision, destruction, or shave removals, the removed tissue is often submitted for pathologic examination. The obtaining of tissue for pathology during the course of these procedures is a routine component of these procedures. This obtaining of tissue is not considered a separate biopsy procedure and is not separately reported. The use of Biopsy procedure code (eg. 11100, 11101) indicates that the procedure to obtain tissue for pathologic examination was performed independently, or was unrelated or distinct from other procedures/services provided at that time."
Please do correct me if I am wrong
