The ATS is petitioning the ICD-10 Coding Update and Coordination Committee to revise the existing ICD-10 for pulmonary hypertension. The current ICD-10 codes use the terms primary and secondary to delineate different categories of pulmonary hypertension, however, the terms primary and secondary have been largely superseded by a more recent terminology based on WHO classifications.
These categories are:
Group 1: Pulmonary Arterial Hypertension
Group 2: Pulmonary Hypertension due to left heart disease
Group 3: Pulmonary Hypertension due to lung disease and/or hypoxia
Group 4: Chronic Thromboembolic Pulmonary Hypertension
Group 5: Pulmonary Hypertension with unclear multifactorial mechanisms
At a recent meeting of the ICD-10 Update and Coordination Committee, ATS member Scott Manaker MD presented the rationale for revising ICD-10 codes to follow the more current nomenclature. In his presentation to the committee, Dr. Manaker noted that both drug treatment and surgical interventions rely on the WHO categories.
While the outcome of the edit process is not yet complete, the ATS expects that the ICD-10 Update and Coordination Committee will accept most of our recommendation. Assuming the pulmonary hypertension codes are amended, the revised codes would be available for use starting October 1, 2017.
