Adverse effect of other narcotics, sequela

This code describes a long-term or residual condition resulting from a previous adverse reaction to a narcotic medication not otherwise specified. These are persistent effects that remain after the acute phase of the adverse drug event has resolved. Examples include chronic pain, organ damage, or neurological deficits directly attributable to the past narcotic adverse effect.

Use this code when documenting a patient presenting with a chronic condition or permanent impairment that is a direct consequence of an adverse effect from a narcotic medication (excluding opium, heroin, and other specified narcotics) that occurred in the past. This code is appropriate when the acute adverse effect has resolved, but its lasting impact requires ongoing management.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past adverse effect of an "other narcotic."
• Do not use for acute adverse effects; refer to the appropriate acute adverse effect code for the initial event.
