Hypothermia, sequela

This code signifies a condition or complication that arises as a long-term consequence of a past episode of hypothermia. It indicates that the patient is currently experiencing a health problem directly attributable to the physiological damage or changes caused by their previous exposure to dangerously low body temperatures. This is not for an acute hypothermic event, but rather for its lasting effects.

Use this code when documenting conditions such as frostbite sequelae (e.g., chronic pain, numbness, tissue loss), neurological deficits (e.g., cognitive impairment, peripheral neuropathy) or cardiovascular complications that are directly linked to a prior hypothermic episode. This code is appropriate when the initial hypothermia has resolved, but its residual effects persist and require ongoing treatment or management.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past hypothermic event.
• Do not use this code for acute hypothermia; refer to codes in the T68 category for current hypothermia.
