Adverse effect of antidiarrheal drugs, sequela

This code signifies a long-term or residual condition resulting from a past adverse reaction to an antidiarrheal medication. This adverse effect is no longer acute but has left a lasting impact on the patient's health. Examples include chronic constipation or persistent electrolyte imbalance due to prior antidiarrheal drug toxicity.

Apply this code when documenting a condition that is a direct consequence of a previous adverse effect from an antidiarrheal drug, and the acute phase of the adverse effect has resolved. This is appropriate for follow-up encounters where the patient is being treated for the lasting complications. Do not use for acute adverse effects or poisoning.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past adverse effect of an antidiarrheal drug.
• A "sequela" code implies the acute event has passed, and the current condition is a residual effect.
