What is the difference between codes 10021 and 10160?

I think there is no big difference between these two codes. For me, the main difference is needle size and it is totally depend upon the nature of the cyst with size of the needle insertion. For 10021, surgeon uses FN means fine gauge needle (usually 18 to 25 gauge sizes) and a syringe to sample fluid or remove clusters of cells from a solid mass. Sometimes surgeon may make several passes to obtain an adequate tissue specimen and it is usually an aspirate, which is a mixture of fluid and cells. Whereas in 10160, surgeon uses a knife or a large bore needle to pierce a fluid filled cavity (such as bulla, cyst, hematoma, abscess etc.) and then withdraw the fluid using a syringe or suction device.
