  • I27.2 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2020 edition of ICD-10-CM I27.2 became effective on October 1, 2019.
  • This is the American ICD-10-CM version of I27.2 - other international versions of ICD-10 I27.2 may differ.

Type 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as I27.2. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • Secondary pulmonary hypertension
  • Secondary pulmonary hypertension (htn)
Clinical Information
  • A disorder characterized by an increase in pressure within the pulmonary circulation due to lung or heart disorder.
  • Increased pressure with the pulmonary circulation, usually secondary to cardiac or pulmonary disease.
  • Increased pressure within the pulmonary circulation due to lung or heart disorder.
  • Increased vascular resistance in the pulmonary circulation, usually secondary to heart diseases or lung diseases.
  • Pulmonary hypertension is high blood pressure in the arteries to your lungs. It is a serious condition for which there are treatments but no cure. If you have it, the blood vessels that carry oxygen-poor blood from your heart to your lungs become hard and narrow. Your heart has to work harder to pump the blood through. Over time, your heart weakens and cannot do its job and you can develop heart failure. There are two main kinds of pulmonary hypertension. One runs in families or appears for no known reason. The other kind is related to another condition, usually heart or lung disease. Treating pulmonary hypertension involves treating the heart or lung disease, medicines, oxygen and sometimes lung transplantation.
