Pnctr w foreign body of thmb w/o damage to nail, init

This code describes a penetrating injury to an unspecified thumb, where an object has broken through the skin and remains embedded. Importantly, this injury does not involve damage to the thumbnail or nail bed. It signifies the initial presentation of such a wound.

Use this code for patients presenting with a foreign body embedded in their thumb, such as a splinter, thorn, or piece of glass, where the specific thumb (left or right) is not documented. This code is appropriate for the first time the patient is seen for this particular injury.

• Ensure documentation explicitly states "foreign body" and "puncture wound."
• Verify that there is no mention of nail damage (e.g., avulsion, laceration of nail bed).
• Confirm this is the initial encounter for this specific injury; subsequent care would use a different encounter character.
