Pnctr w fb of unsp great toe w/o damage to nail, sequela

This code describes a puncture wound to an unspecified great toe that includes a foreign body, such as a splinter or glass. Importantly, there is no associated damage to the toenail. The "S" at the end indicates that this is a sequela, meaning it's a late effect or complication of an earlier injury.

Use this code for documentation of a chronic or residual condition resulting from a puncture wound to the great toe with a retained foreign body, where the initial injury occurred in the past. This would apply when a patient presents for treatment of ongoing issues directly attributable to the foreign body from a prior puncture, such as chronic pain, infection, or granuloma formation.

• Ensure documentation clearly states the presence of a foreign body and that the toenail is intact.
• The "S" seventh character indicates a sequela; verify that the encounter is for a late effect of the original injury.
• Always code the specific type of foreign body if known, using an additional external cause code (e.g., W45.0XXA for needle, W45.1XXA for splinter).
