Infct fol a procedure, organ and space surgical site, subs

This code signifies an infection that develops in the organ or deep tissue spaces accessed during a surgical procedure. It specifically applies to encounters where the patient is receiving follow-up care for this established infection, rather than the initial diagnosis or treatment.

Use this code when a patient presents for ongoing management, such as wound care, antibiotic therapy adjustments, or monitoring, of a previously diagnosed post-procedural organ or space surgical site infection. This includes scenarios where the infection was identified during an earlier encounter and the patient is now returning for subsequent treatment.

• Requires an additional code to identify the specific infection (e.g., bacterial, fungal).
• Always sequence this code after the primary diagnosis for the infection itself.
• Distinguish from T81.43XA (initial encounter) and T81.43XS (sequela) based on the patient's stage of care for the infection.
