Adverse effect of stimulant laxatives, subsequent encounter

This code indicates a patient is experiencing an unintended and undesirable reaction to a stimulant laxative, such as bisacodyl or senna, during a follow-up visit for the adverse effect. These reactions can range from abdominal cramping and electrolyte imbalances to more severe issues like cathartic colon.

Apply this code when a patient presents for ongoing management or evaluation of an adverse effect caused by a stimulant laxative, and this is not the initial encounter for the problem. This includes situations where the patient is being monitored for resolution of symptoms or for complications arising from the initial adverse reaction.

• Always sequence this code after the code(s) for the specific adverse effect(s) manifested (e.g., K59.00 for constipation, E87.6 for hypokalemia).
• Ensure documentation clearly states the stimulant laxative as the cause of the adverse effect and that this is a subsequent encounter.
• Do not use this code for poisoning, underdosing, or initial encounters for adverse effects.
