Adverse effect of antipruritics, sequela

This code signifies a long-term or residual health problem resulting from an adverse reaction to a medication used to relieve itching. The initial adverse effect has resolved, but a lasting consequence or complication persists. This could include chronic skin changes, organ damage, or other persistent issues directly attributable to the antipruritic.

Use this code when documenting a patient presenting with a chronic condition or permanent damage that is a direct and lasting consequence of a previous adverse effect from an antipruritic medication. This applies even if the original acute adverse reaction has passed. Examples include persistent dermatitis, scarring, or organ dysfunction that developed after an adverse drug event with an anti-itch agent.

• Always sequence this code after the code for the specific sequela (e.g., chronic dermatitis, renal failure).
• Ensure documentation clearly links the current chronic condition to a past adverse effect of an antipruritic.
• Do not use for acute adverse effects; those require codes from the initial encounter or active treatment phase.
