0.000What This Code Means
Emphysema that does not fit into the standard categories of unilateral, panlobular, or centrilobular types, or a combination of different emphysema patterns.
Coding Tips
Clinical Significance
Other emphysema captures emphysema types not classified as unilateral, panlobular, or centrilobular, including paraseptal (distal acinar) emphysema and bullous emphysema. Paraseptal emphysema involves the distal alveoli adjacent to the pleura and septa, and is associated with spontaneous pneumothorax in young adults.
Documentation Requirements
- ✓CT imaging describing the specific type of emphysema (paraseptal, bullous, etc.)
- ✓Documentation confirming the emphysema does not fit centrilobular (J43.2) or panlobular (J43.1) classification
- ✓Pulmonary function testing if available
- ✓Clinical impact assessment: symptoms, functional limitations, complications (e.g., pneumothorax history)
- ✓Treatment plan and monitoring strategy
