Encompasses venous thromboembolisms not elsewhere classified.
Follow this step-by-step guide to choose the correct ICD-10 code.

No
This decision tree is for left lower extremity DVT only. Re-evaluate diagnosis.
When to use each related code
| Description |
|---|
| Left leg DVT: blood clot in a deep vein. |
| Right leg DVT: blood clot in a deep vein. |
| Pulmonary embolism: blood clot in lung artery. |
Missing or incorrect laterality (left) can impact reimbursement and quality metrics. Ensure proper coding for left leg DVT.
Unspecified acuity (acute, chronic, or sequelae) can lead to coding errors. Document and code the DVT's temporal status.
Failing to document and code any underlying conditions contributing to the DVT (e.g., malignancy, trauma) can affect severity and risk adjustment.
Q: What are the most reliable diagnostic imaging modalities for confirming suspected deep vein thrombosis of the left lower extremity in a symptomatic patient?
A: When a patient presents with symptoms suggestive of left leg deep vein thrombosis (DVT), such as swelling, pain, and redness, confirming the diagnosis accurately and efficiently is crucial. Compression ultrasonography (CUS) is generally the first-line imaging modality due to its high sensitivity and specificity for proximal DVT, non-invasive nature, and widespread availability. If the CUS is inconclusive, particularly for suspected distal DVT or isolated calf vein thrombosis, alternative imaging like venography (contrast or magnetic resonance venography - MRV) may be considered. D-dimer testing, while useful for ruling out DVT in low-risk patients, is not specific enough to confirm a diagnosis in symptomatic individuals. The choice of imaging modality should be based on the individual patient's clinical presentation, risk factors, and local resource availability. Consider implementing a standardized diagnostic pathway for DVT evaluation to ensure consistent and evidence-based practice. Explore how different imaging techniques compare in sensitivity and specificity for various DVT locations.
Q: How do I differentiate between cellulitis and left leg deep vein thrombosis (DVT) in a patient presenting with lower extremity swelling and erythema?
A: Differentiating between cellulitis and DVT in the left lower extremity can be challenging as both conditions present with overlapping symptoms like swelling, erythema, and pain. However, distinguishing features can aid in accurate diagnosis. In DVT, the swelling is often more pronounced and may involve the entire leg, while cellulitis usually presents with localized swelling and more defined borders of erythema. Palpable tenderness along the affected vein, a positive Homan's sign (although not highly reliable), and the presence of risk factors for DVT (e.g., recent surgery, immobility, family history) further increase suspicion for DVT. Cellulitis, on the other hand, often exhibits increased warmth and localized tenderness, and may be accompanied by fever or lymphadenopathy. A detailed patient history, physical examination focusing on the distribution and characteristics of the swelling and erythema, and targeted diagnostic imaging (CUS for DVT) are essential for accurate diagnosis. Learn more about the clinical features and diagnostic algorithms for differentiating these conditions to avoid misdiagnosis and ensure appropriate treatment.
Patient presents with complaints consistent with possible deep vein thrombosis (DVT) in the left lower extremity. Presenting symptoms include left leg pain, swelling, and tenderness to palpation along the calf and thigh. The patient reports the onset of symptoms was approximately [duration] ago and describes the pain as [character of pain, e.g., aching, throbbing, sharp]. The patient denies any history of trauma to the left leg. Physical examination reveals [objective findings, e.g., edema, erythema, warmth, palpable cord]. Differential diagnosis includes muscle strain, cellulitis, Baker's cyst, and superficial thrombophlebitis. To confirm the diagnosis of left leg DVT, a venous duplex ultrasound of the left lower extremity has been ordered. Assessment includes left lower extremity DVT, and pending ultrasound results. Plan includes anticoagulation therapy with [medication name and dosage] pending ultrasound confirmation, patient education regarding DVT risk factors, signs and symptoms of pulmonary embolism, and importance of medication compliance. Follow-up appointment scheduled in [duration] to review ultrasound results and discuss further management. ICD-10 code I80.22 (deep vein thrombosis of left lower extremity) is documented for billing and coding purposes. Patient advised to return to the clinic or seek emergency care if symptoms worsen or new symptoms develop, such as shortness of breath or chest pain.
