Adverse effect of digestants, sequela

This code signifies a long-term or residual condition resulting from a previous adverse reaction to a digestant medication. These are effects that persist after the acute phase of the adverse event has resolved, indicating a lasting impact on the patient's health.

This code is appropriate when a patient presents with a chronic or permanent health problem directly attributable to an adverse effect of a digestant, and the acute phase of the reaction has passed. Examples include persistent esophageal stricture following caustic injury from a digestant, or chronic malabsorption due to long-term damage from a digestant.

• Always use this code as a secondary diagnosis, following the code for the specific sequela.
• Ensure documentation clearly links the current condition to a past adverse effect of a digestant.
• Do not use this code for acute adverse effects; refer to the appropriate acute adverse effect code for initial encounters.
