Post–Dental Extraction Tooth Infection Coding
A tooth infection that develops after a dental extraction is most directly reported as infection following a procedure (surgical site infection) when the infection is documented as postoperative/procedural. [1]
The ICD-10-CM code for infection following a procedure, superficial incisional surgical site, initial encounter is T81.41XA. [1]
Alternative Dental Infection Code When Not Classified as Postprocedural
When the infection is documented as a periapical abscess rather than a postoperative/procedural infection, the ICD-10-CM code K04.7 (Periapical abscess without sinus) is reported. [2]
