2025 ICD-10-CM code I27.24
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Pulmonary heart disease and diseases of pulmonary circulation - Other secondary pulmonary hypertension Diseases of the circulatory system (I00-I99) Feed
Chronic thromboembolic pulmonary hypertension; a type of secondary pulmonary hypertension caused by blood clots in the lungs.
Medical necessity for coding I27.24 is established by the presence of clinical symptoms and diagnostic evidence of chronic thromboembolic disease and associated pulmonary hypertension.The severity of symptoms and hemodynamic findings should support the diagnosis and justify the need for treatment and monitoring.
Diagnosis and management of chronic thromboembolic pulmonary hypertension typically involves a cardiologist or pulmonologist. This includes detailed patient history, physical examination, diagnostic testing (e.g., echocardiography, pulmonary angiography, CT pulmonary angiography), and appropriate treatment, which may include anticoagulation therapy, pulmonary thromboendarterectomy, or other interventions.
In simple words: This code describes a type of high blood pressure in the blood vessels of the lungs caused by long-term blood clots.These clots block the flow of blood, causing pressure to build up in the lungs and making the heart work harder.
I27.24, Chronic thromboembolic pulmonary hypertension, is an ICD-10-CM code representing a form of secondary pulmonary hypertension resulting from chronic blood clots (thromboemboli) obstructing pulmonary arteries.This condition leads to increased pressure in the pulmonary circulation, placing strain on the right side of the heart.The diagnosis requires evidence of chronic thromboembolic disease and associated hemodynamic changes characteristic of pulmonary hypertension.
Example 1: A 60-year-old female with a history of deep vein thrombosis presents with progressive shortness of breath and chest pain.Pulmonary angiography confirms chronic thromboembolic disease, and right heart catheterization reveals elevated pulmonary artery pressure.The diagnosis of I27.24 is established., A 72-year-old male with a history of recurrent pulmonary emboli undergoes a CT pulmonary angiogram showing multiple chronic thromboembolic lesions.He experiences exertional dyspnea and reduced exercise tolerance.I27.24 is assigned., A 45-year-old female with antiphospholipid syndrome develops recurrent pulmonary emboli resulting in chronic thromboembolic pulmonary hypertension.Right heart catheterization confirms elevated pulmonary vascular resistance.I27.24 is used in conjunction with codes reflecting her underlying condition.
Complete history and physical examination, including symptoms (dyspnea, chest pain, syncope), risk factors (prior DVT/PE, inherited clotting disorders), and relevant past medical history.Diagnostic imaging studies (e.g., CTPA, pulmonary angiography), echocardiography to assess right ventricular function, and right heart catheterization to confirm diagnosis with hemodynamic measurements are crucial.Treatment details should also be documented.
** The diagnosis of chronic thromboembolic pulmonary hypertension requires correlation of clinical findings, imaging evidence of chronic thromboemboli, and hemodynamic confirmation of pulmonary hypertension.Consider using additional codes to describe associated conditions or comorbidities.
