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

This code describes a puncture wound to an unspecified finger, where a foreign object remains embedded in the tissue, and there is no associated damage to the fingernail or nail bed. The "sequela" designation indicates that this code is used for the late effects or complications of an initial injury, after the acute phase has passed.

This code is appropriate for documenting a patient presenting for follow-up care or treatment of persistent issues related to an old puncture wound of the finger, where a foreign body was retained. This includes situations where the foreign body was not initially removed, or where complications such as chronic pain, infection, or granuloma formation are being addressed long after the initial injury.

• Always ensure documentation clearly states the presence of a retained foreign body and the absence of nail damage.
• The "S" seventh character mandates this code be used for sequelae, meaning the acute injury has already been treated or resolved.
• Do not use this code for initial encounters or acute care of the puncture wound; instead, refer to the acute injury codes.
