Tox eff of nitro & oth nitric acids & esters, slf-hrm, init

This diagnosis code signifies a patient presenting with adverse health effects resulting from the deliberate ingestion or exposure to nitroglycerin, nitric acids, or related esters, with the explicit intent of self-harm. The patient is in the initial phase of treatment for these toxic effects.

Apply this code when documenting an emergency department visit or initial hospitalization for a patient who has intentionally overdosed on medications like nitroglycerin or other nitrate compounds. This includes cases where the patient explicitly states their intent to self-harm or evidence strongly suggests such intent.

• Always confirm the intent of self-harm through physician documentation.
• Ensure the encounter is the initial treatment for this specific toxic event. Subsequent care would use different encounter characters.
• Specify the exact substance if known and documented, though this code covers a class of substances.
