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

This code signifies a cut or tear to the skin of an unspecified thumb that does not involve a foreign object. The injury is superficial, meaning it does not extend deep enough to damage the nail structure itself. This is the initial visit for this specific injury.

Apply this code when documenting a patient's first presentation for a simple laceration on their thumb, where no foreign material is embedded in the wound and the nail plate or bed remains intact. Examples include minor cuts from paper, knives, or other sharp objects that only affect the skin.

• Ensure documentation explicitly states "without foreign body" and "without damage to nail."
• Verify this is the patient's first encounter for this specific injury to justify the "A" (initial encounter) seventh character.
• If a foreign body is present or nail damage occurred, a different code should be selected.
