Infection following a procedure, unspecified, sequela

This code signifies a past infection that occurred as a complication of a medical or surgical procedure, where the specific type of infection is not documented. It is used when the patient is presenting for treatment of a residual effect or condition that is a direct consequence of that prior procedural infection, rather than the active infection itself.

Apply this code when a patient is seen for a long-term complication or sequela directly attributable to a previously resolved, but unspecified, post-procedural infection. This would include conditions like chronic pain, scarring, organ damage, or functional impairment resulting from the infection. Do not use this code for an active infection.

• Requires documentation of a prior procedural infection and a current condition directly linked as a sequela.
• Always sequence this code after the code(s) for the specific sequela being treated.
• Avoid using if the specific type of infection is known; instead, use a more specific T81.4- code.
