Contusion of left thumb without damage to nail, init encntr

This code signifies a bruise to the left thumb, indicating soft tissue injury without any associated damage to the fingernail or nail bed. It represents a closed injury resulting from blunt force trauma, such as being struck or crushed.

Apply this code for initial evaluations and treatments of a patient presenting with a contusion of their left thumb. This includes scenarios like a patient hitting their thumb with a hammer or catching it in a door, where the nail remains intact.

• Ensure documentation explicitly states "left thumb" and confirms the absence of nail damage.
• Verify this is the patient's first encounter for this specific injury; subsequent encounters will require a different seventh character.
• Distinguish from sprains, fractures, or open wounds, which would necessitate different codes.
