Pnctr w/o fb of right thumb w/o damage to nail, init

This code signifies a penetrating injury to the right thumb, caused by a sharp object, that does not involve a retained foreign body. The wound specifically excludes any damage to the nail or nail bed, indicating a superficial puncture.

Apply this code when a patient presents with a fresh puncture wound to the right thumb, and clinical examination confirms no foreign material is embedded and the nail structure is intact. This is appropriate for the initial treatment of such an injury.

• Ensure documentation explicitly states "without foreign body" and "without damage to nail."
• Verify the encounter is the initial treatment for this specific injury.
• Later encounters for follow-up care would require a different seventh character (e.g., D for subsequent, S for sequela).
