I27.0 is a billable ICD code used to specify a diagnosis of primary pulmonary hypertension. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code I270 is used to code Pulmonary hypertension

Pulmonary hypertension (PH) is an increase of blood pressure in the pulmonary artery, pulmonary vein, or pulmonary capillaries, together known as the lung vasculature, leading to shortness of breath, dizziness, fainting, leg swelling and other symptoms. Pulmonary hypertension can be a severe disease with a markedly decreased exercise tolerance. It was first identified by Ernst von Romberg in 1891. According to the most recent classification, it can be one of six different types.

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)

416.0
Primary pulmonary hypertension (exact match)

This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 416.0 was previously used, I27.0 is the appropriate modern ICD10 code.
