Asphyx d/t being trap in a (discarded) refrig, slf-hrm, subs

This code signifies a subsequent encounter for an injury resulting from intentional self-harm by asphyxiation due to being trapped inside a refrigerator. The patient has previously received initial treatment for this specific self-inflicted injury.

Use this code when documenting follow-up care, such as wound checks, psychological evaluations, or management of complications, for a patient who intentionally asphyxiated themselves by being trapped in a refrigerator. This applies after the initial treatment for the acute injury has been completed.

• Always assign an external cause code (X71.-) to identify the intent and mechanism of injury.
• Ensure the "D" seventh character is appropriate for a subsequent encounter, indicating ongoing care after the initial treatment.
• Consider additional codes for any associated physical injuries or mental health diagnoses.
