Other, multiple and ill-defined fractures of lower limb, open

This code signifies an open fracture involving multiple or unspecified locations within the lower limb. An open fracture indicates that the skin and soft tissues overlying the fracture site have been compromised, exposing the bone to the external environment. This can include various bones of the leg, ankle, or foot, where the exact fracture site or number of fractures is not precisely documented.

Use this code when documentation clearly states an open fracture of the lower limb, but the specific bone(s) involved are not detailed, or multiple fractures are present without precise anatomical localization. This code is appropriate when the physician's notes describe an "open fracture of the lower leg, site unspecified" or "multiple open fractures of the foot."

• Always seek clarification from the provider if a more specific fracture site can be identified to allow for a more precise code.
• Distinguish carefully between open (compound) and closed (simple) fractures; this code is exclusively for open fractures.
• Avoid using this code if a more specific ICD-9-CM code for an open fracture of a particular lower limb bone (e.g., tibia, fibula, femur) is available and supported by documentation.
