Contusion of abdominal wall, sequela

This code signifies a bruise or contusion of the abdominal wall, indicating a past injury that is now causing a residual effect or complication. It is used when the acute phase of the contusion has passed, and the patient is experiencing a long-term consequence directly attributable to the original trauma.

Apply this code when documenting a patient presenting with persistent pain, scarring, nerve damage, or other chronic issues stemming from a previously sustained abdominal wall contusion. This is appropriate for follow-up encounters where the original injury is no longer acute but its lasting impact is being addressed.

• Requires a seventh character of 'S' for sequela, indicating a late effect.
• Always link to an external cause code (V00-Y99) if known, to describe the original incident that caused the contusion.
• Do not use for acute contusions; those require an 'A' (initial encounter) or 'D' (subsequent encounter) seventh character.
