Contusion of unsp little finger w/o damage to nail, init

This diagnosis code signifies a bruise to the little finger where the nail itself is not injured. It indicates a blunt force trauma resulting in superficial tissue damage, such as discoloration and swelling, without an open wound or fracture. This is the first time the patient is being treated for this specific injury.

Use this code for patients presenting with a closed injury to the little finger, exhibiting signs of a contusion like ecchymosis or tenderness, and where the nail plate and nail bed are confirmed to be intact. This code is appropriate for the initial visit for this specific injury.

• Ensure documentation explicitly states "little finger" and confirms the absence of nail damage.
• Verify that this is the patient's first encounter for this specific injury; subsequent encounters would require a different seventh character.
• If an open wound, fracture, or nail damage is present, a more specific code should be selected.
