|---|---|
| Blockage in lung artery, often from a blood clot. | Sudden shortness of breath, chest pain, cough, confirmed by CT or V/Q scan. |
| Clot in deep leg vein, can lead to pulmonary embolism. | Leg pain, swelling, redness, use when PE suspected but not confirmed, or isolated DVT. |
| Chronic lung blood vessel changes after multiple PEs. | Long-term breathing difficulties, pulmonary hypertension after confirmed prior PE. |
Best-practice checklist
- ✓Acute Pulmonary Embolism (PE) diagnosis documentation:
- ✓Confirm PE diagnosis with objective evidence.
- ✓Document symptom onset, duration, and severity.
- ✓Specify location and size of embolus if known.
- ✓Include Wells score or Geneva score assessment.
- ✓Detail diagnostic tests (e.g., CTPA, V/Q scan) and results.
Common pitfalls to avoid
Coding for acute PE requires specifying if it's saddle, segmental, subsegmental, etc. for accurate reimbursement.
Presence or absence of right heart strain impacts severity and must be clearly documented for proper coding (e.g., ICD-10-CM I26.01, I26.02).
Discrepancies between imaging results and clinical findings can lead to coding errors. CDI specialists must clarify discrepancies for accurate code assignment.
Best-practice tips
- 01Document PE risk factors: immobility, surgery, prior VTE
- 02Specify PE location: saddle, lobar, segmental, subsegmental
- 03Code PE laterality: right, left, or bilateral for ICD-10
- 04Correlate DVT and PE diagnoses for accurate reimbursement
- 05Document thrombolysis rationale for compliance and CDI

Ready-to-paste narrative
Patient presents with sudden onset of shortness of breath (dyspnea), pleuritic chest pain, and tachycardia. Symptoms began acutely approximately two hours prior to presentation. Risk factors for pulmonary embolism (PE) include recent prolonged immobility due to a long car trip, as reported by the patient. Differential diagnosis includes acute coronary syndrome, pneumonia, pneumothorax, and pleurisy. Physical examination reveals tachypnea, oxygen saturation of 92% on room air, and a normal cardiac exam with no murmurs, rubs, or gallops. Electrocardiogram (ECG) shows sinus tachycardia with nonspecific T-wave changes. D-dimer level is elevated. Computed tomography pulmonary angiography (CTPA) was performed and confirms the diagnosis of acute pulmonary embolism, demonstrating a filling defect in the right lower lobe pulmonary artery. The patient is hemodynamically stable. Treatment plan includes initiation of anticoagulation therapy with intravenous heparin, followed by transition to oral anticoagulants such as apixaban, rivaroxaban, or warfarin. Patient education provided regarding the risks and benefits of anticoagulation, including bleeding precautions. Follow-up appointment scheduled for monitoring of INR levels and assessment of treatment response. Prognosis for complete resolution with appropriate anticoagulation is good. ICD-10 code I26.9 for pulmonary embolism without acute cor pulmonale is documented. Medical necessity for CTPA justified by high clinical suspicion based on patient presentation and risk factors.
Common questions and answers
What are the most reliable clinical signs and symptoms for diagnosing acute pulmonary embolism in a hemodynamically stable patient?+
While no single symptom or sign definitively diagnoses acute pulmonary embolism (APE) in a hemodynamically stable patient, some are highly suggestive and warrant further investigation. Dyspnea (especially sudden onset) and pleuritic chest pain are the most common presenting complaints. Tachypnea, tachycardia, and low-grade fever may also be present. Signs of deep vein thrombosis (DVT), such as leg swelling, pain, or tenderness, can be a valuable clue, as APE often arises from DVT. However, many patients present with nonspecific symptoms or even remain asymptomatic. Therefore, clinical suspicion based on risk factors (recent surgery, immobilization, active malignancy, etc.) coupled with suggestive symptoms and signs should prompt further diagnostic testing, such as a D-dimer assay and CT pulmonary angiography (CTPA). Explore how implementing a standardized risk assessment and diagnostic algorithm can improve early detection and management of acute PE.
How do I differentiate acute pulmonary embolism from other causes of chest pain and shortness of breath in the emergency department?+
Differentiating acute pulmonary embolism (APE) from other causes of chest pain and shortness of breath in the emergency department requires a systematic approach. The differential diagnosis includes myocardial infarction, pneumonia, pneumothorax, pericarditis, and aortic dissection, among others. Begin with a thorough history and physical exam, focusing on risk factors for APE (e.g., recent surgery, long-haul flight, personal or family history of venous thromboembolism) and characteristic symptoms like pleuritic chest pain and sudden onset dyspnea. Electrocardiogram (ECG) findings can help differentiate APE from myocardial infarction, while chest X-ray can identify pneumonia, pneumothorax, or other pulmonary pathology. D-dimer testing can be helpful in ruling out APE in low-risk patients. However, CTPA remains the gold standard for diagnosing APE and can often distinguish it from other conditions. Consider implementing the PERC rule (Pulmonary Embolism Rule-out Criteria) for patients at low risk to reduce unnecessary CTPA scans. Learn more about the latest guidelines for risk stratification and diagnosis of APE.
What are the recommended anticoagulation strategies for treating acute pulmonary embolism in patients with and without cancer?+
Anticoagulation is the cornerstone of treatment for acute pulmonary embolism (APE). For patients *without* active cancer, direct oral anticoagulants (DOACs), such as apixaban, rivaroxaban, and edoxaban, are generally preferred over vitamin K antagonists (VKAs) like warfarin due to their ease of use and lack of routine monitoring. However, for patients *with* active cancer, low molecular weight heparin (LMWH), such as enoxaparin or dalteparin, followed by a DOAC or LMWH for extended treatment, is often recommended. LMWH has demonstrated superior efficacy in reducing recurrent venous thromboembolism (VTE) in cancer patients. The duration of anticoagulation depends on the patient's individual risk factors and the nature of the provoking event. For provoked APE, a minimum of three months of anticoagulation is typically recommended. Consider implementing strategies for optimizing patient adherence to anticoagulation therapy and exploring the role of thrombolytic therapy in specific patient populations with massive or submassive PE.
