Adverse effect of tricyclic antidepressants, sequela

This code indicates a long-term or residual health problem resulting from a past adverse reaction to a tricyclic antidepressant medication. These are conditions that persist after the acute phase of the adverse effect has resolved, such as chronic neurological deficits or organ damage.

Use this code when documenting a patient presenting with a lasting health issue directly attributable to a previous adverse effect from a tricyclic antidepressant. This applies to conditions that are no longer acute but represent a permanent or chronic consequence of the drug reaction.

• Always sequence this code after the code for the specific sequela (e.g., chronic kidney disease, persistent neuropathy).
• Ensure documentation clearly links the current condition to a past adverse effect of a tricyclic antidepressant.
• Do not use for acute adverse effects; refer to the appropriate acute adverse effect code for those situations.
