Adverse effect of enzymes, subsequent encounter

This code signifies a harmful or unintended reaction experienced by a patient due to the therapeutic use of an enzyme, occurring during a follow-up visit after the initial treatment. It indicates that the patient is still being managed for the negative consequences of the enzyme administration.

Apply this code when a patient presents for ongoing care related to an adverse effect from an enzyme, such as pancreatic enzymes, thrombolytics, or other therapeutic enzymes. This would include follow-up appointments for monitoring, managing symptoms, or adjusting treatment for conditions like allergic reactions, gastrointestinal disturbances, or bleeding complications attributed to enzyme therapy.

• Ensure documentation clearly states the adverse effect is due to an enzyme and that this is a subsequent encounter.
• Always code the specific manifestation of the adverse effect first, followed by this code.
• Verify the encounter type to differentiate between initial, subsequent, and sequela encounters.
