Tox eff of corrosv alkalis & alk-like substnc, slf-hrm, init

This code signifies a patient presenting with adverse health effects resulting from exposure to corrosive alkaline or alkali-like substances, such as lye or strong cleaning agents. The exposure is determined to be intentional self-harm, indicating a deliberate act to cause injury. The "initial encounter" designation means this code is used for the first time the patient is receiving active treatment for this specific injury.

Apply this code when documenting the initial treatment for a patient who has ingested, inhaled, or had skin contact with a corrosive alkali in a suicide attempt or other self-injurious behavior. This includes emergency department visits, initial hospital admissions, or the first outpatient visit for this specific event. Subsequent encounters for the same injury would require a different seventh character.

• Always confirm the intent (intentional self-harm) and the substance type (corrosive alkali) from the medical record.
• Remember to also code any specific manifestations of the toxic effect, such as esophageal burns or respiratory distress.
• Do not use this code for accidental exposures or assault; those scenarios have different seventh characters or base codes.
