Superficial foreign body, left ankle, initial encounter

This code signifies the presence of a foreign object embedded superficially in the skin or subcutaneous tissue of the patient's left ankle. This typically involves objects that have not penetrated deeper structures like muscle, tendon, or bone.

Use this code when a patient presents for initial evaluation and treatment of a foreign body, such as a splinter, glass shard, or metal fragment, located just under the skin of the left ankle. This applies to the first encounter for this specific injury.

• Ensure the foreign body is explicitly documented as "superficial" and located on the "left ankle."
• Verify that this is the patient's first visit for this particular injury to justify the "initial encounter" seventh character.
• Do not use for foreign bodies that have penetrated deeper tissues or for follow-up care.
