There is an initial phase coded as "cellulitis" or "preabscess cellulitis" without pus formation or microabscess; the second phase is the "abscess" formation with macroscopic collection of pus; the third phase is the presence of "abscess cavity" with necrosis and clots, and finally, the endothelialized cavity without pus coded as "pseudoaneurysm."
