icd 10 code for pulmonary artery hypertension

Pulmonary arterial hypertension (PAH) is a type of cardiovascular disease classified under the ICD-10 code I27.0. It is marked by an abnormal elevation in pulmonary artery pressure, which can lead to increased strain on the right ventricle and potentially result in heart failure. The diagnosis of PAH primarily depends on clinical symptoms, physical examinations, and supportive diagnostic tests including electrocardiograms and echocardiograms.

PAH can be categorized based on its severity and underlying causes. Primary pulmonary arterial hypertension, also referred to as idiopathic pulmonary arterial hypertension, is the most prevalent form, with its etiology being largely unknown but potentially linked to genetic and autoimmune factors. Secondary pulmonary arterial hypertension arises from other diseases or conditions, such as chronic obstructive pulmonary disease, sleep apnea syndrome, and pulmonary infections.

Patients with PAH should avoid strenuous activities and excessive fatigue in their daily lives, maintain a positive mental attitude, and minimize significant emotional fluctuations. Regular monitoring of blood pressure and heart rate is essential, and they must adhere to the prescribed treatment regimen without discontinuing medication or altering dosages without medical advice. In the event of symptoms like shortness of breath, chest pain, or syncope, prompt medical attention is crucial.
