Blizzard (snow)(ice), sequela

This code signifies a health condition or injury that is a long-term or delayed consequence of exposure to a blizzard. It indicates that the patient's current medical issue is a direct result of the severe weather event, even if the onset of symptoms was not immediate. This could encompass a range of physical or psychological sequelae.

Use this code when documenting a patient's current medical condition that is a direct, lingering effect of a past blizzard. This applies to situations where the initial acute phase of the blizzard's impact has passed, but the patient is still experiencing related health issues. Examples include chronic frostbite complications, persistent musculoskeletal pain from falls during the blizzard, or psychological trauma.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., T34.111A for frostbite of right hand, initial encounter).
• Ensure the medical record clearly documents the causal link between the blizzard and the current condition.
• The "S" in the 7th character indicates sequela, meaning the patient is seen for complications or conditions that arise as a direct result of the initial injury or condition.
