Puncture wound with foreign body of right upper arm, sequela

This code describes a puncture wound in the right upper arm that occurred in the past and left a foreign body embedded in the tissue. The "sequela" designation indicates that this code is used to report a late effect or complication of the original injury, rather than the acute injury itself. The foreign body is still present and causing ongoing issues.

Use this code when a patient presents with a chronic issue or complication stemming from a puncture wound to the right upper arm where a foreign body was retained. This applies to situations where the initial injury has healed, but the retained foreign body is now causing symptoms or requiring intervention. Examples include chronic pain, infection, or nerve impingement due to the foreign body.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, infection).
• Ensure documentation clearly states the presence of a foreign body and that the current encounter addresses a late effect of the original puncture wound.
• Do not use this code for the initial acute puncture wound or if the foreign body has been removed.
