0.000What This Code Means
Long-term lung inflammation characterized by an abnormal increase in a specific type of white blood cell (eosinophils) in the lungs.
Coding Tips
- •Document any known underlying cause (drug reaction, parasitic infection, malignancy) if identified
- •Confirm eosinophilic infiltration through pathology or imaging findings documented in the medical record
Clinical Significance
Chronic eosinophilic pneumonia is a rare but clinically important condition characterized by progressive respiratory symptoms with peripheral and pulmonary eosinophilia. It is significant for risk adjustment because it requires long-term corticosteroid therapy, frequently relapses when steroids are tapered, and maps to COPD HCCs reflecting its chronic nature and resource intensity.
Documentation Requirements
- ✓Peripheral blood eosinophilia with documentation of levels
- ✓Chest imaging showing characteristic peripheral 'photographic negative of pulmonary edema' pattern
- ✓Bronchoalveolar lavage showing eosinophilic predominance if performed
- ✓Exclusion of other causes (parasitic infections, drug reactions, ABPA, eosinophilic granulomatosis with polyangiitis)
- ✓Duration and chronicity of symptoms
- ✓Treatment plan including corticosteroid regimen and taper schedule
- ✓Relapse history if applicable
Commonly Confused Codes
J82.83 (Eosinophilic asthma) — eosinophilic asthma is primarily an airway disease; chronic eosinophilic pneumonia is an interstitial/alveolar processJ82.89 (Other pulmonary eosinophilia) — use J82.81 specifically when the chronic eosinophilic pneumonia pattern is documentedM30.1 (Eosinophilic granulomatosis with polyangiitis) — systemic vasculitis with eosinophilia vs. isolated pulmonary eosinophiliaJ84.89 (Other specified interstitial pulmonary diseases) — use J82.81 when eosinophilic pattern is confirmed
