I am trying to code an I&D - Abscess Perineum. Code 56405 matches this but directly above the code in the CPT book if says for incision and drainage of sebaceous cyst, furuncle, or abscess see 10040, 10060, 10061. Can anyone tell me which code i should be using? Why is there a code for this it it tells you to use something else. I am unclear on the difference. Thanks
