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

This code signifies a puncture injury to an unspecified thumb that occurred in the past and is now presenting with a residual effect or complication. The wound did not involve a foreign body and the nail was not damaged at the time of the initial injury. This code is used when the patient is being treated for a long-term consequence of the original puncture.

Use this code for encounters where a patient is being managed for a sequela (e.g., chronic pain, scar tissue, limited range of motion) resulting from a previously sustained puncture wound to an unspecified thumb. This applies when the initial injury has healed but its lasting effects are the focus of the current treatment. Do not use for the initial acute injury.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the original injury, if known.
• Ensure documentation clearly indicates the encounter is for a sequela and not the acute injury.
• Verify that the puncture wound was indeed without a foreign body and without nail damage.
