Contusion of unspecified part of colon, sequela

This code signifies a bruise to an unspecified portion of the colon, indicating a past injury that is still causing symptoms or requiring ongoing care. It represents the long-term effects or complications arising from an initial colonic contusion, rather than the acute injury itself.

Use this code when documenting a patient presenting with persistent symptoms (e.g., pain, altered bowel habits) directly attributable to a previously sustained colonic contusion. It is appropriate for follow-up encounters where the sequela of the initial injury is the focus of treatment or evaluation.

• Always link this sequela code to an external cause code (V00-Y99) if known, to describe the circumstances of the original injury.
• Ensure documentation clearly supports the "sequela" nature of the condition, indicating it's not an acute injury.
• Do not use this code for acute contusions; instead, use the appropriate acute contusion code (e.g., S36.529A).
