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

This code signifies a patient presenting with adverse health effects resulting from the deliberate self-poisoning with nitroglycerin or related nitric acid compounds. The encounter being coded is not the initial presentation for this event, but rather a follow-up or subsequent visit for ongoing management or complications.

Apply this code for follow-up visits where a patient is being monitored or treated for the sequelae of an intentional overdose of nitroglycerin, isosorbide dinitrate, or similar substances. This includes appointments for managing cardiac complications, hypotension, or other systemic effects after the initial acute phase.

• Ensure documentation clearly states "intentional self-harm" and that it's a subsequent encounter.
• Always code the specific manifestation of the toxic effect (e.g., hypotension, arrhythmia) in addition to this code.
• Do not use for accidental exposures or therapeutic misadventures; those require different intent codes.
