Injury of intra-abdominal organs (S36) ICD-10-CM

About the S36 Code Range

The ICD-10 code section S36 covers injuries to intra-abdominal organs, including the spleen, liver, gallbladder, bile duct, pancreas, stomach, intestines, colon, rectum, peritoneum, and other abdominal structures. These codes describe a variety of trauma types such as contusions, lacerations, unspecified injuries, and primary blast injuries.

This section is used to precisely document internal organ injuries resulting from trauma or accidents. For example, codes like S36.00XA capture unspecified spleen injuries, including closed injuries or those with an open wound into the abdominal cavity. The code S36.112A is used for initial encounters of liver contusions, which might also be called liver hematoma or traumatic liver hemorrhage. Injuries to the pancreas are categorized by location and severity, with terms such as traumatic injury or tear of the pancreas linked to codes like S36.200A for head of pancreas injuries. Lacerations of intestines and colon cover a range of injuries, from serosal tears to perforations, and the use of seventh characters indicates initial, subsequent, or sequela encounters. These detailed codes allow medical coders to select the appropriate ICD-10 code for conditions often referred to as blunt abdominal trauma, traumatic rupture, or internal organ injury in the abdomen.
