Fat embolism

This code signifies the presence of fat globules in the bloodstream, which can obstruct blood flow and lead to organ damage, particularly in the lungs and brain. It is a serious complication often associated with trauma or orthopedic procedures.

Assign this code when documentation clearly indicates a diagnosis of fat embolism, typically following long bone fractures, orthopedic surgery (e.g., total joint replacement), or other significant trauma. Supporting documentation should detail the clinical presentation, such as respiratory distress, neurological changes, or petechial rash, and a confirmed diagnosis.

• Differentiate from pulmonary embolism (415.1x) which involves blood clots, not fat globules.
• Always sequence this code as a secondary diagnosis when it is a complication of an underlying condition or procedure.
• Ensure the medical record specifies "fat embolism" rather than a general term like "embolism" to justify its use.
