Official Coding Guidelines
Postprocedural wound/obstetric wound infection sequencing with sepsis(b) Sepsis due to a postprocedural infection For sepsis following a postprocedural wound (surgical site) infection, a code from T81.41 to T81.43, Infection following a procedure, T81.49, Infection following a procedure, other surgical site, or a code from O86.00 to O86.03, Infection of obstetric surgical wound, or code O86.09, Infection of obstetric surgical wound, other surgical site, that identifies the site of the infection should be sequenced first, if known. Assign an additional code for sepsis following a procedure (T81.44) or sepsis following an obstetrical procedure (O86.04). Use an additional code to identify the infectious agent. If the patient has severe sepsis, the appropriate code from subcategory R65.2 should also be assigned with the additional code(s) for any acute organ dysfunction.
