ICD-10 Code Families
Complete code families applicable to I26.99
When to use each related code
| Description | When to use |
|---|---|
| Blood clots in both lungs. | Confirmed bilateral pulmonary embolism on imaging (e.g., CTPA). |
| Blood clot in one lung. | Confirmed unilateral pulmonary embolism on imaging. Specify affected side (right/left). |
| Suspected but unconfirmed PE. | Clinical suspicion of PE but imaging inconclusive or pending. Follow up with definitive diagnosis. |
Best-practice checklist
- ✓Document PE symptoms: dyspnea, chest pain, tachypnea
- ✓Confirm bilateral PE with CTPA or VQ scan results
- ✓Specify location and size of emboli in both lungs
- ✓Assess risk factors: DVT, immobility, recent surgery
- ✓Note Wells score or Geneva score for PE probability
Common pitfalls to avoid
Coding for "bilateral" PE requires distinct documentation of emboli in BOTH lungs. Unilateral or unspecified documentation leads to inaccurate coding (e.g., I26.99 vs. I26.02).
A saddle PE (I26.03) is a specific type of bilateral PE. Accurate coding requires clear physician documentation to differentiate and avoid coding errors.
Distinguishing between acute (I26) and chronic (I27) PE is crucial for proper coding and reimbursement. Documentation must clearly specify the chronicity.
Best-practice tips
- 01Document PE location, size, and acuity for accurate ICD-10 coding (I26.92).
- 02Capture thrombus characteristics for complete CDI and risk stratification.
- 03Query physician for DVT association to ensure appropriate VTE treatment.
- 04Ensure documentation supports medical necessity for anticoagulation therapy.
- 05Regularly review and update clinical guidelines for VTE prophylaxis and management.
Step-by-step checklist
- 1
Verify DVT risk factors (recent surgery, immobility)
- 2
Confirm bilateral PE on CTPA or VQ scan imaging
- 3
Assess for right heart strain (ECG, echo)
- 4
Check for respiratory distress (tachypnea, hypoxia)
- 5
Review for prior PE or thrombophilia history
Ready-to-paste narrative
Patient presents with acute onset of dyspnea and chest pain, suggestive of pulmonary embolism. Symptoms include shortness of breath, pleuritic chest pain, and increased heart rate. The patient reports no recent surgery or prolonged immobility, but does have a family history of thromboembolic disease. Physical examination reveals tachycardia and mild tachypnea. Lung auscultation reveals clear breath sounds bilaterally. D-dimer levels are elevated. Computed tomography angiography (CTA) of the chest demonstrates bilateral pulmonary emboli, confirming the diagnosis of bilateral pulmonary embolism. Differential diagnoses considered included pneumonia, myocardial infarction, and pleurisy. Given the patient's presentation and imaging findings, the diagnosis of bilateral PE is established. Treatment plan includes initiation of anticoagulation therapy with heparin, followed by transition to oral anticoagulants such as warfarin or a direct oral anticoagulant (DOAC). Patient education provided regarding risks, benefits, and potential side effects of anticoagulation. Follow-up appointment scheduled for monitoring of INR levels and assessment of treatment response. Prognosis for recovery is good with appropriate anticoagulation therapy. ICD-10 code I26.92, Pulmonary embolism without acute cor pulmonale, is assigned. CPT codes for the CTA chest and subsequent physician services will be documented appropriately for medical billing and coding purposes. Patient advised to return to the emergency department if symptoms worsen.
Common questions and answers
How does the clinical presentation of bilateral pulmonary embolism differ from unilateral PE, and what specific signs should I look for in a suspected bilateral PE patient?+
While both unilateral and bilateral pulmonary embolism (PE) can present with dyspnea, chest pain, and tachycardia, bilateral PE often presents with more severe symptoms due to increased obstruction of pulmonary vasculature. Specifically, clinicians should be highly suspicious of bilateral PE in patients presenting with acute onset severe dyspnea, hypoxemia disproportionate to the chest x-ray findings, signs of right heart strain (e.g., elevated jugular venous pressure, right ventricular heave), or syncope. The presence of these signs should prompt immediate further investigation, including a CT pulmonary angiography (CTPA) or ventilation/perfusion (V/Q) scan. Explore how risk stratification tools, such as the Wells Score or Geneva Score, can aid in assessing the probability of PE in these patients.
What are the recommended anticoagulation treatment strategies for acute bilateral pulmonary embolism, and what factors should influence the choice between DOACs and LMWH/warfarin?+
Current guidelines recommend direct oral anticoagulants (DOACs) such as rivaroxaban, apixaban, or edoxaban as the preferred initial treatment for most patients with acute bilateral pulmonary embolism, given their ease of administration and comparable efficacy to low molecular weight heparin (LMWH) followed by warfarin. However, factors that favor LMWH/warfarin over DOACs include severe renal impairment (creatinine clearance < 30 mL/min), active cancer, or patient inability to afford DOACs. For hemodynamically unstable patients with bilateral PE, thrombolytic therapy may be considered in consultation with a specialist. Consider implementing a structured follow-up plan to monitor treatment efficacy and potential bleeding complications. Learn more about the latest guidelines for PE management from reputable sources like the American College of Chest Physicians (CHEST).
When is a vena cava filter indicated in a patient with confirmed bilateral pulmonary emboli, and what are the potential risks and benefits of IVC filter placement in this context?+
An inferior vena cava (IVC) filter is indicated in patients with confirmed bilateral pulmonary embolism (PE) when anticoagulation is contraindicated (e.g., active bleeding, recent surgery) or when recurrent PE occurs despite adequate anticoagulation. The benefits of IVC filter placement include reducing the risk of further pulmonary emboli; however, the risks include complications related to filter placement (e.g., bleeding, infection) and the potential for long-term complications such as IVC thrombosis. The decision to place an IVC filter should be made on a case-by-case basis after careful consideration of the risks and benefits, in consultation with a vascular specialist. Learn more about the appropriate use and management of IVC filters in the context of bilateral PE to optimize patient outcomes.
