Adverse effect of thrombolytic drugs, subsequent encounter

This code describes a harmful or unintended reaction to a thrombolytic medication that occurs during a follow-up visit or hospitalization. It indicates that the patient is experiencing ongoing complications from a previously administered "clot-busting" drug.

Use this code when documenting a patient's adverse reaction to a thrombolytic agent, such as bleeding, allergic reaction, or re-occlusion, during any encounter after the initial treatment. This applies to follow-up appointments, subsequent hospital admissions for managing the adverse effect, or ongoing outpatient care.

• Always sequence this code after the code for the specific adverse effect (e.g., hemorrhage, anaphylaxis).
• Ensure the documentation clearly links the adverse effect to the thrombolytic drug and indicates a subsequent encounter.
• Do not use this code for poisoning, underdosing, or initial adverse reactions; those require different seventh characters.
