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

This code describes a persistent complication or late effect stemming from a puncture wound to the left little finger, where a foreign body was present at the time of the initial injury, and the nail was not damaged. The "sequela" designation indicates that the current encounter is for a condition directly resulting from that past injury, rather than the acute injury itself.

Use this code when documenting a patient encounter for a long-term issue, such as chronic pain, nerve damage, scar tissue formation, or infection, that is a direct consequence of a previously sustained puncture wound with a foreign body in the left little finger. This applies when the original wound has healed, but its lasting effects are being addressed.

• Always assign a sequela code (ending in "S") as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past puncture wound with foreign body in the specified digit.
• Do not use this code for the initial treatment of the acute puncture wound; instead, use the appropriate acute injury code.
