Adverse effect of other antidepressants, sequela

This code signifies a long-term or residual condition resulting from an adverse reaction to an antidepressant medication not specifically classified elsewhere. These are persistent health problems that manifest after the initial acute adverse effect has resolved, or are chronic conditions directly attributable to the past antidepressant exposure.

Apply this code when documenting a chronic or permanent sequela, such as tardive dyskinesia or persistent sexual dysfunction, that is definitively linked to a past adverse effect of an antidepressant. This is used when the patient is no longer experiencing the acute adverse effect, but rather a lasting consequence.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., G24.0 for drug-induced tardive dyskinesia).
• Ensure thorough documentation explicitly links the current chronic condition to a past adverse effect of an antidepressant.
• Distinguish from acute adverse effects (use 5th or 6th character A or D) or poisoning (T36-T50 with 5th or 6th character 1-4).
