About coding wound abscess
The ICD-10-CM code for wound abscess is T81.49 (Infection following a procedure, other surgical site).
Within T81.4, choose T81.49 (other surgical site) only when documentation doesn't support a more specific option: unspecified (T81.40), superficial incisional surgical site (T81.41), deep incisional surgical site (T81.42), organ and space surgical site (T81.43) and sepsis following a procedure (T81.44).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).
