Pulmonary hypertension, unspecified
ICD-10 I27.20 is a billable code used to indicate a diagnosis of pulmonary hypertension, unspecified.
Pulmonary hypertension (PH) is a condition characterized by elevated blood pressure in the pulmonary arteries, which can lead to right heart failure and other serious complications. The anatomy involved includes the right ventricle, pulmonary arteries, and the pulmonary circulation system. Clinically, patients may present with symptoms such as dyspnea, fatigue, chest pain, and syncope, which can be mistaken for other respiratory or cardiac conditions. Disease progression can vary widely; in some patients, it may remain stable for years, while in others, it can rapidly worsen, leading to significant morbidity and mortality. Diagnostic considerations for pulmonary hypertension include echocardiography, right heart catheterization, and various imaging studies to assess the severity and underlying causes. The unspecified nature of I27.20 indicates that the specific etiology of the pulmonary hypertension is not documented, which may include idiopathic, heritable, or secondary causes such as left heart disease or chronic lung disease.

I27.20 covers pulmonary hypertension that is unspecified, meaning the underlying cause is not documented. This may include idiopathic pulmonary hypertension or secondary forms without specific identification.
I27.20 should be used when the specific cause of pulmonary hypertension is unknown or not documented. If the etiology is known, more specific codes such as I27.21 or I27.29 should be utilized.
Documentation should include clinical findings, results from echocardiograms or right heart catheterization, and any relevant patient history that indicates the presence of pulmonary hypertension without specifying the cause.
