Multiple fractures of ribs, unsp side, init for clos fx

This code signifies the initial diagnosis of multiple rib fractures where the specific side (left or right) is not documented. It indicates a closed fracture, meaning the skin remains intact over the injury site. This diagnosis typically results from significant blunt force trauma to the chest.

Apply this code for patients presenting with multiple rib fractures following an acute injury, where imaging confirms the fractures but the laterality is not specified in the documentation. This is appropriate for the initial treatment phase of a closed, unspecified multiple rib fracture.

• Ensure documentation clearly states "multiple" rib fractures and specifies "closed" and "initial encounter."
• If laterality (left or right) is documented, use a more specific code from the S22.4- series.
• Do not use this code for subsequent encounters or for open fractures.
