Burn third degree of unsp mult fngr (nail), inc thumb, subs

This code signifies a full-thickness burn affecting the skin and underlying tissues of an unspecified number of fingers, including the thumb, where the burn has progressed beyond the initial healing phase. This type of burn results in permanent tissue destruction and typically requires surgical intervention. The "subsequent encounter" indicates that the patient is receiving follow-up care for this previously diagnosed injury.

Apply this code when documenting ongoing treatment, such as wound care, debridement, skin grafting, or physical therapy, for a third-degree burn to multiple fingers (including the thumb) that was initially treated in a prior encounter. This is appropriate for patients returning for scheduled follow-up appointments or complications arising during the healing process.

• Ensure documentation clearly specifies "third degree" and involvement of "multiple fingers" (including thumb) for accurate code assignment.
• Confirm the encounter is for follow-up care, not the initial treatment of the burn, to justify the "D" seventh character.
• Always review the medical record for laterality (left, right, bilateral) if specified, as more specific codes may be available.
