Contusion of head of pancreas, sequela

This code signifies a long-term or late-developing complication resulting from a blunt force injury to the head of the pancreas. It indicates that the initial contusion has resolved, but its lasting effects, such as chronic pain, pancreatic insufficiency, or pseudocyst formation, are now being addressed.

Apply this code when documenting the residual effects or complications of a previously sustained contusion to the head of the pancreas. This is appropriate for follow-up encounters where the acute injury has healed, but the patient continues to experience issues directly attributable to that past trauma.

• Requires a seventh character "S" to indicate sequela.
• Do not use for the initial acute injury; that would require an "A" (initial encounter) or "D" (subsequent encounter) seventh character.
• Always link with an external cause code (V00-Y99) to describe the circumstances of the original injury, if known.
