Pnctr w fb of left great toe w damage to nail, sequela

This code signifies a past puncture injury to the left great toe where a foreign object was embedded, resulting in lasting damage to the toenail. This is not an acute injury but rather a long-term consequence or complication arising from the original wound.

Apply this code when documenting a patient presenting with chronic nail deformity, discoloration, or other persistent issues on the left great toe, directly attributable to a previously sustained puncture wound with a retained foreign body. This code is appropriate for follow-up care related to the sequelae, not the initial injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., onychodystrophy).
• Ensure documentation clearly links the current nail damage to a prior puncture wound with a foreign body.
• Verify the laterality (left) and specific digit (great toe) are accurately reflected in the medical record.
