Adverse effect of emetics, sequela

This code signifies a long-term or residual condition resulting from a past adverse reaction to an emetic agent. It indicates that the patient is experiencing a lasting health problem directly attributable to the previous use of a substance intended to induce vomiting.

Use this code when documenting a chronic or permanent sequela, such as persistent esophageal damage or neurological deficits, that developed as a consequence of an adverse effect from an emetic. This applies when the acute adverse effect has resolved, but its lasting impact remains.

• Always sequence this code after the code for the specific sequela (e.g., K22.1 for esophagitis).
• Ensure documentation clearly links the current condition to a past adverse effect of an emetic.
• Do not use for acute adverse effects; use the appropriate acute adverse effect code (e.g., T47.7X5A) for initial encounters.
