Abrasion of left thumb, sequela

This code signifies a superficial injury to the skin of the left thumb, characterized by scraping or rubbing off of the epidermis, where the injury itself is no longer acute but has resulted in a long-term consequence or late effect. This could include scarring, chronic pain, or functional impairment directly attributable to the original abrasion.

Apply this code when documenting a patient presenting with a current condition or complication that arose as a direct result of a previously sustained abrasion to the left thumb. This is appropriate for follow-up encounters addressing the residual effects of the original injury, not the initial acute injury itself.

• Always ensure documentation clearly links the current condition to the past abrasion of the left thumb.
• Do not use this code for the initial treatment of an acute abrasion; instead, use the appropriate acute injury code.
• Consider additional codes for specific sequelae (e.g., scar formation, chronic pain) if documented.
