Injury of peritoneum, sequela

This code signifies a long-term or late-effect condition resulting from a previous injury to the peritoneum. It is used when the initial acute injury has resolved, but the patient continues to experience symptoms or complications directly attributable to that past peritoneal trauma.

Apply this code when documenting conditions such as adhesions, chronic pain, or functional impairment that are a direct consequence of a prior injury to the peritoneum. This is appropriate for follow-up encounters where the sequela of the original injury is being treated or evaluated, rather than the acute injury itself.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., peritoneal adhesions).
• Ensure documentation clearly links the current condition to a past peritoneal injury.
• The "S" in the 7th character indicates a sequela and should be used for encounters after the initial treatment of the acute injury.
