Major laceration of right external jugular vein, sequela

This code signifies a long-term complication or late effect stemming from a significant tear or cut to the right external jugular vein. This could include chronic pain, scarring, nerve damage, or persistent circulatory issues directly attributable to the original injury. The "sequela" indicates that the acute injury has resolved, but its lasting impact is still present.

Apply this code when documentation clearly indicates a current condition that is a direct consequence of a previously sustained major laceration of the right external jugular vein. This is appropriate for follow-up encounters where the patient is being treated for the chronic effects, not the acute injury itself. Physician notes should explicitly link the current complaint to the past external jugular vein trauma.

• Always sequence the sequela code first, followed by any codes for the specific manifestation of the sequela (e.g., chronic pain, scar formation).
• Ensure documentation specifies "right" external jugular vein; laterality is crucial for accurate coding.
• Distinguish between an acute injury (S15.221A-D) and a sequela; the "S" seventh character is key for sequela coding.
