Unsp comp fol infusion and theraputc injection, sequela

This code signifies a long-term or residual effect of an unspecified complication that occurred after an infusion or therapeutic injection. It indicates that the acute phase of the complication has resolved, but the patient continues to experience a related issue. The specific nature of the original complication is not documented or is unknown.

Use this code when a patient presents with a current condition that is a direct consequence of a past, unspecified complication from an infusion or therapeutic injection. This applies to situations where the initial complication is no longer active but has left a lasting impact requiring ongoing management or documentation.

• Always sequence this code after the code(s) for the specific sequela or residual condition being treated.
• Ensure documentation clearly links the current condition to a past complication of an infusion or injection, even if the original complication's nature is unspecified.
• Avoid using this code for acute complications; instead, use the appropriate acute complication code from the T80 series.
