Superficial frostbite of unspecified finger(s), init encntr

This code signifies a first-time diagnosis of superficial frostbite affecting one or more fingers, without specifying which finger(s) are involved. Superficial frostbite, also known as frostnip, involves freezing of the skin and subcutaneous tissue, but not deeper structures. It typically presents with numbness, tingling, and pale or waxy skin that may feel firm to the touch.

Apply this code when documentation confirms superficial frostbite of the fingers, and the specific digit(s) affected are not identified. This is appropriate for the initial visit for this condition. Examples include patients presenting to the emergency department after cold exposure with symptoms consistent with mild finger frostbite.

• Ensure the documentation explicitly states "superficial" or "first-degree" frostbite.
• Only use this code for the initial encounter for this specific frostbite episode.
• If the specific finger(s) are documented (e.g., left index finger), a more specific code from the T33.5- series should be used.
