AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2017 Quarter 4; New/Revised ICD-10-CM Diagnosis Codes
Pulmonary Hypertension
Subcategory I27.2 , Other secondary pulmonary hypertension, has been expanded and new codes created to differentiate the various types of pulmonary hypertension (PH). Secondary PH is caused by other conditions. Pulmonary hypertension is defined as increased pressure in the pulmonary arteries, and is clinically classified into five groups: Group 1: Pulmonary arterial hypertension (PAH) is the most widely recognized category of PH, and includes primary pulmonary hypertension ( I27.0 ) and secondary pulmonary arterial hypertension ( I27.21 ). Idiopathic and inheritable PAH are other terms that refer to primary pulmonary hypertension, as well. Some other secondary causes...

Article Overview
This article explains the pulmonary hypertension topic as reflected in ICD-10-CM, with emphasis on how the condition is clinically grouped and how the subcategory structure was expanded to distinguish different forms of secondary pulmonary hypertension. It is relevant to coders, CDI staff, and clinicians working with cardiovascular, pulmonary, and related secondary-condition documentation. The discussion covers the broad classification of pulmonary hypertension, associated conditions, and general coding context for the related ICD-10-CM codes.
Why This Topic Matters
Pulmonary hypertension can arise from multiple underlying conditions, and the article helps readers understand the updated code structure used to reflect those different clinical scenarios. That matters for accurate documentation review, code selection, and consistent reporting across encounters involving secondary causes or associated conditions.
