Poisn by unsp nonopi analgs/antipyr/antirheu, assault, init

This code signifies a deliberate act of harm involving an unspecified non-opioid pain reliever, fever reducer, or anti-inflammatory medication. The patient has been intentionally poisoned by another individual using one of these drug types, and this encounter represents the initial presentation for treatment.

Apply this code when documentation clearly indicates an assault involving an unknown or unspecified non-opioid analgesic, antipyretic, or antirheumatic drug. This is appropriate for the first visit where the poisoning is diagnosed and treatment initiated.

• Always sequence this code first if it is the primary reason for the encounter.
• Ensure the documentation explicitly states "assault" as the intent of the poisoning.
• Do not use if the specific drug class (e.g., salicylates, NSAIDs) is known; use a more specific T39 subcategory instead.
