Question:

If my physician excises a lesion and the pathologist says it is a diagnosis that is considered “uncertain behavior” by ICD-9, do I use the benign excision of skin lesion CPT code or the malignant CPT code when I bill?

Answer:

Good question! When the diagnosis is categorized with an “uncertain behavior” ICD-9 code, then you will use the excision of benign skin lesion CPT code for the removal.
