Poisoning by antivaricose drugs, including sclerosing agents

This code signifies an adverse reaction or overdose specifically due to medications used to treat varicose veins, including substances like sclerosing agents. It covers systemic toxic effects resulting from the ingestion, injection, or absorption of these drugs.

Apply this code when documentation clearly indicates a patient presenting with signs and symptoms of poisoning or adverse effects directly attributable to antivaricose drugs. This includes accidental overdose, intentional self-harm, or therapeutic misadventure involving these specific agents.

• Always sequence this code as a primary diagnosis when it is the reason for the encounter.
• Document the specific antivaricose drug involved, if known, to support the code selection.
• Distinguish between poisoning (adverse effect due to incorrect use or overdose) and adverse effect in therapeutic use (correctly prescribed and administered drug causing an unexpected reaction).
