Adverse effect of unspecified antidepressants, sequela

This code signifies a long-term or residual health problem resulting from a past adverse reaction to an antidepressant medication, where the specific type of antidepressant is not documented. It indicates that the patient experienced an undesirable effect from the drug, and now, after the acute phase has passed, they are dealing with a lasting consequence.

This code is appropriate when a patient presents with a chronic condition or permanent impairment directly attributable to an adverse effect of an antidepressant, and the medical record does not specify which antidepressant caused the reaction. Examples include persistent neurological deficits, chronic organ damage, or lasting psychological sequelae.

• Always sequence this code after the code for the specific sequela (e.g., chronic kidney disease, persistent tremor).
• Ensure documentation clearly links the current condition to a past adverse effect of an antidepressant.
• Avoid using this code if the specific antidepressant is known; instead, use a more specific code from the T43.2- subcategory.
