Poisoning by oth nonsteroid anti-inflam drugs, acc, init

This code signifies an accidental overdose or adverse reaction to a non-specified nonsteroidal anti-inflammatory drug (NSAID) other than salicylates, pyrazolones, propionic acid derivatives, or acetic acid derivatives. The patient's symptoms are a direct result of unintentional exposure to the medication. This code is used for the initial phase of treatment for such an event.

Apply this code when a patient presents with symptoms of poisoning due to an accidental ingestion or exposure to an NSAID not specifically classified elsewhere in T39.3. Examples include an adult mistakenly taking too many doses of an unknown NSAID or a child accidentally ingesting an NSAID medication. This code is appropriate for the emergency department visit or initial hospitalization for managing the acute poisoning.

• Ensure the poisoning is explicitly documented as accidental or unintentional.
• Verify the specific NSAID involved is not classifiable to a more specific T39.3 subcategory.
• Confirm this is the initial encounter for the poisoning event; subsequent care would use a different seventh character.
