Open bite of abd wall, periumb rgn w/o penet perit cav, init

This code describes an open wound in the periumbilical area of the abdomen that does not extend into the abdominal cavity. This type of injury involves a break in the skin and underlying tissues, but the peritoneum remains intact.

Use this code for initial encounters involving a laceration, puncture, or other open wound to the abdominal wall specifically around the navel, where diagnostic imaging or exploration confirms no penetration of the peritoneal lining. This applies to injuries such as a stab wound or deep cut that affects only the superficial layers.

• Ensure documentation explicitly states "without penetration into peritoneal cavity" for accurate code assignment.
• Verify the wound location is specifically periumbilical; other abdominal wall regions have different codes.
• This "A" initial encounter suffix is used for the period of active treatment for the injury.
