Thromboembolism in the puerperium

This code signifies the occurrence of a thromboembolic event, such as deep vein thrombosis (DVT) or pulmonary embolism (PE), specifically during the puerperium. This period encompasses the six weeks following childbirth, a time of increased risk for thrombotic complications due to physiological changes.

Apply this code when documentation clearly indicates a diagnosis of thromboembolism in a patient who is within 42 days postpartum. Supporting documentation should include diagnostic imaging (e.g., ultrasound for DVT, CT angiogram for PE) confirming the thrombus, along with the patient's postpartum status.

• Ensure the documentation explicitly states the thromboembolic event occurred during the puerperium; otherwise, a general thromboembolism code may be more appropriate.
• Code any specific type of thromboembolism (e.g., DVT of lower extremity, PE) as a secondary diagnosis.
• Verify the timeframe; if the event occurs outside the puerperium, even if pregnancy-related, this code is not applicable.
