Pnctr w fb of r little finger w damage to nail, sequela

This code signifies a past injury to the right little finger involving a puncture wound that introduced a foreign object, specifically affecting the nail structure. The "sequela" indicates that this code is used for complications or conditions arising directly from the initial injury, after the acute phase has passed.

This code is appropriate when a patient presents with a chronic issue, such as persistent pain, infection, deformity, or functional impairment, directly attributable to a puncture wound with a retained foreign body in the right little finger's nail area. It should be used for follow-up encounters addressing these long-term effects, not for the initial acute injury.

• Always ensure documentation clearly links the current condition to the past puncture wound and retained foreign body.
• Verify that the injury specifically involved the right little finger and the nail structure.
• Do not use this code for the initial acute injury; instead, use the appropriate acute injury code with the 7th character "A" (initial encounter).
