Superfic frostbite of abd wall, low back and pelvis, sequela

This code signifies the long-term effects or complications arising from a superficial frostbite injury to the abdominal wall, lower back, or pelvic region. These sequelae can include persistent skin changes, altered sensation, or chronic pain in the affected areas, occurring after the initial acute injury has resolved.

Apply this code when documenting conditions directly attributable to a past superficial frostbite episode affecting the specified body regions. This is appropriate for follow-up encounters addressing residual symptoms or complications, such as scarring, dysesthesia, or chronic discomfort, that are a direct result of the original frostbite.

• Always use this code as a secondary diagnosis, following a code for the specific sequela being treated (e.g., chronic pain, scar).
• Ensure documentation clearly links the current condition to a previous superficial frostbite injury of the abdominal wall, lower back, or pelvis.
• Do not use for acute frostbite injuries; refer to the appropriate acute frostbite codes (T33.3XXA, T33.3XXD) for initial and subsequent encounters.
