A positive diagnostic peritoneal lavage (DPL) indicates an accumulation of fluid in the peritoneal cavity, which often suggests the presence of intra-abdominal injury or bleeding. In coding practices, particularly in the context of trauma injuries, a positive DPL is not considered a standalone injury. Instead, it serves as a diagnostic tool that might lead to the identification of underlying injuries, such as organ lacerations or hematomas, necessitating further coding based on the specific findings or injuries that it uncovers.

When coding for trauma or injuries, it's essential to document the actual injuries or conditions that are revealed through diagnostic procedures like DPL. Therefore, without an accompanying diagnosis or identification of an injury, a positive DPL itself does not meet the criteria for coding as an independent injury. This distinction is critical for accurate medical coding and for ensuring that all relevant procedures and injuries are appropriately captured in clinical documentation.
