Unsp comp following infusion and therapeutic injection, subs

This code signifies an unspecified adverse event or problem that arises after a patient has received an infusion or therapeutic injection, and the patient is presenting for follow-up care related to this complication. The nature of the complication is not documented with enough specificity to assign a more precise code.

Use this code when a patient returns for management of a complication from an infusion or injection, and the specific type of complication (e.g., infection, hemorrhage, allergic reaction) is not clearly identified in the medical record. This is appropriate for subsequent visits where the initial complication has already been addressed or is being monitored.

• Always strive for a more specific complication code if documentation allows.
• Ensure the encounter is clearly documented as a "subsequent encounter" for the complication.
• Do not use for complications of blood transfusions, as these have separate codes.
