Personal history of pulmonary embolism

This code signifies that a patient has a documented history of having experienced a pulmonary embolism (PE) in the past. While the acute event has resolved, the patient remains at an increased risk for future embolic events or may have residual effects from the prior PE.

This code is appropriate for patients who have a confirmed prior diagnosis of pulmonary embolism, regardless of the cause or how long ago it occurred. It should be used when the patient is no longer experiencing the acute PE but their medical history is relevant to current care, such as for risk assessment or management of long-term sequelae.

• Do not use this code for an active or acute pulmonary embolism; use the appropriate I26.x code instead.
• Always sequence this code as a secondary diagnosis when the history is relevant to the current encounter.
• Ensure documentation clearly states a "history of" or "previous" pulmonary embolism to support its use.
