Pulmonary eosinophilia, not elsewhere classified

In Other respiratory diseases principally affecting the interstitium (J80-J84), chapter 10: Diseases of the Respiratory System

4 billable codes under J82: all are a CC; 1 map to HCC 280 (Chronic Obstructive Pulmonary Disease, Interstitial Lung Disorders, and Other Chronic Lung Disorders).A CC or MCC (major CC) is a secondary diagnosis that raises the MS-DRG payment. An HCC counts toward a Medicare Advantage patient's risk score.

About the condition

Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.

Eosinophilic Disorders

Eosinophils are a type of white blood cell. They help fight off infections and play a role in your body's immune response. They can also build up and cause inflammation.

Lung Diseases

When you breathe, your lungs take in oxygen from the air and deliver it to the bloodstream. The cells in your body need oxygen to work and grow. During a normal day, you breathe nearly 25,000 times. People with lung disease have difficulty breathing. Millions of people in the U.S. have lung disease. If all types of lung disease are lumped together, it is the number three killer in the United States.

Code history

Valid since FY2016, when ICD-10-CM took effect on October 1, 2015.

FY2021: Subcodes were added, so J82 is no longer billable on its own. New codes for cases coded here before: J82.81 (Chronic eosinophilic pneumonia), J82.82 (Acute eosinophilic pneumonia), J82.83 (Eosinophilic asthma), J82.89 (Other pulmonary eosinophilia, not elsewhere classified).
