I am trying to figure out if I can use a procedure code for I & D, or if this would be considered part of the E/M service.

"left forearm with 1 cm round nodule with central black coloring. Under sterile technique the area was explored with 22 gauge needle, no foreign body found, pus and blood drained and culture obtained"

Maybe there is a different code that better describes this procedure. This is a pediatric patient and not something we commonly code. Any help would be appreciated.

Thank you!
