Toxic effect of smoke, intentional self-harm, subs encntr

This code signifies a toxic reaction to smoke exposure resulting from a deliberate act of self-harm, where the patient is receiving follow-up care for the initial injury. It indicates that the patient is beyond the acute phase of treatment but still requires ongoing management related to the smoke inhalation.

Apply this code for patients presenting for subsequent visits, such as follow-up appointments, medication adjustments, or therapy sessions, after an initial admission or encounter for intentional smoke inhalation. This includes situations where the patient is being monitored for long-term respiratory effects or psychological sequelae of the self-harm attempt.

• Always sequence this code after the primary mental health diagnosis (e.g., depression, suicidal ideation) if applicable.
• Ensure documentation clearly states the intentional nature of the smoke exposure and that the encounter is not for the initial acute treatment.
• Verify that the "D" seventh character is appropriate for subsequent care, not initial or sequela.
