Unsp opn wnd abd wall, unsp q w/o penet perit cav, sequela

This code describes a healed or residual condition resulting from a past open injury to the abdominal wall. The original wound's specific location within the abdomen was not documented, and it did not extend into the peritoneal cavity. The "sequela" designation indicates that this code is used for complications or conditions arising long after the initial injury has resolved.

Use this code when documenting a patient presenting with a long-term consequence of a previously sustained, unspecified open wound to the abdominal wall that did not penetrate the peritoneum. This could include chronic pain, scar tissue, or functional limitations directly attributable to the old injury. It is appropriate when the acute phase of the injury has passed, and the patient is being treated for a residual effect.

• Always ensure the "S" (sequela) seventh character is appropriate for the encounter, indicating a late effect.
• Verify documentation clearly states the original wound did not penetrate the peritoneal cavity.
• If the specific abdominal quadrant is known, a more precise code without "unspecified quadrant" should be used.
