Unsp opn wnd abd wall, r flank with penet perit cav, sqla

This code signifies a chronic or late-effect open injury to the right flank of the abdominal wall that has breached the peritoneal cavity. This type of wound is characterized by a break in the skin and underlying tissues, extending into the abdominal lining, with the specific nature of the wound not documented. The "sequela" designation indicates that this code is used for complications or conditions arising directly from an initial injury that has already healed or is in its late stages.

Use this code when documenting a patient presenting with a long-term complication, scar, or persistent issue directly attributable to a past open wound of the right flank that penetrated the peritoneal cavity. This would apply to scenarios where the initial acute injury has resolved, but the patient is now being treated for a residual effect. Examples include chronic pain, adhesions, or a persistent fistula stemming from the original penetrating trauma.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic pain, adhesions).
• Ensure documentation clearly links the current condition to a previous penetrating open wound of the right flank.
• Avoid using this code for acute injuries; instead, select an appropriate acute injury code from the S31.6 series without the "S" seventh character.
