Burn of first degree of unsp thumb (nail), subs encntr

This code signifies a superficial burn affecting only the outermost layer of skin on an unspecified thumb. It indicates the burn is in the healing phase, following the initial treatment. There is no blistering, broken skin, or deeper tissue involvement.

Apply this code for follow-up visits where a first-degree burn of the thumb is being monitored or treated after the initial encounter. This would include scenarios like dressing changes, wound checks, or patient education regarding continued care for a previously diagnosed first-degree thumb burn.

• Ensure the documentation specifies "first degree" and clearly identifies the thumb as the affected site.
• Verify the encounter is indeed a "subsequent encounter" and not the initial treatment for the burn.
• Confirm no laterality (right/left) is specified for the thumb in the medical record.
