Visceral and Parietal Pleural Invasion
Notes
**Note 1:** Physician statement of Visceral and Parietal Pleural Invasion can be used to code this data item when no other information is available. **Note 2:** A surgical resection must be done to determine if the visceral and/or parietal pleural is involved. **Note 3:** Do not use imaging findings to code this data item **Note 4:** Code 9 when + A FNA only is performed. A FNA is not adequate to assess pleural layer invasion + Surgical resection of the primary site is performed and there is no mention of visceral and/or parietal pleural invasion| Code | Description |
