Corros third degree of unsp mult fngr, not inc thumb, subs

This code signifies a severe, full-thickness burn injury affecting multiple fingers, excluding the thumb, where the damage extends through all layers of skin and potentially into underlying tissue. The injury is characterized by charring, eschar formation, and a lack of sensation in the affected area. This specific code is used for follow-up care after the initial treatment of such an injury.

Apply this code when documenting subsequent encounters for patients receiving ongoing care for third-degree corrosion of multiple fingers (excluding the thumb). This includes scenarios like wound care, debridement, skin grafting procedures, or monitoring for complications during the healing phase. It is appropriate for any visit after the initial acute treatment.

• Ensure the documentation clearly specifies "third degree" and involves "multiple fingers" excluding the thumb.
• Verify that the encounter is for follow-up care, indicated by the "D" seventh character.
• Always review the medical record for laterality if specified, though this code is for unspecified laterality.
