Code Classification

  • Diseases of the circulatory system
    (I00–I99)
    • Pulmonary heart disease and diseases of pulmonary circulation
      (I26-I28)
      • Other pulmonary heart diseases
        (I27)

I27.20 is a billable diagnosis code used to specify a medical diagnosis of pulmonary hypertension, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The code is commonly used in cardiology medical specialties to specify clinical concepts such as hypertension.

Unspecified diagnosis codes like I27.20 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Episodic pulmonary hypertension
  • Hyperuricemia, pulmonary hypertension, renal failure, alkalosis syndrome
  • Mild pulmonary hypertension
  • Moderate pulmonary hypertension
  • Precapillary pulmonary hypertension
  • Progressive pulmonary hypertension
  • Pulmonary arterial hypertension
  • Pulmonary hypertension
  • Pulmonary hypertensive venous disease
  • Severe pulmonary hypertension

Clinical Classification

Clinical Information

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Replacement Code

I2720 replaces the following previously assigned ICD-10-CM code(s):

  • I27.2 - Other secondary pulmonary hypertension

Convert I27.20 to ICD-9-CM

  • ICD-9-CM Code: 416.8 - Chr pulmon heart dis NEC
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Pulmonary Hypertension

Pulmonary hypertension (PH) is high blood pressure in the arteries to your lungs. It is a serious condition. If you have it, the blood vessels that carry 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.

Symptoms of PH include:

  • Shortness of breath during routine activity, such as climbing two flights of stairs
  • Tiredness
  • Chest pain
  • A racing heartbeat
  • Pain on the upper right side of the abdomen
  • Decreased appetite

As PH worsens, you may find it hard to do any physical activities.

There are two main kinds of PH. One runs in families or appears for no known reason. The other kind is related to another condition, usually heart or lung disease.

There is no cure for PH. Treatments can control symptoms. They involve treating the heart or lung disease, medicines, oxygen, and sometimes lung transplantation.
