PD-L1 is recommended by treatment guidelines for lung cancer to determine if the patient may benefit from checkpoint inhibitor drugs (immunotherapy). It is a new data item for cases diagnosed 1/1/2025+.
| 0.0 | No PD-L1 expression identified Tumor Proportion Score (TPS) = 0% |
| 0.1-100.0 | 0.1-100.0 PD-L1 expression Tumor Proportion Score (TPS) = 0.1%-100.0% |
| XXX.2 | PD-L1 expression absent AND Tumor Proportion Score (TPS) stated as negative |
| XXX.3 | PD-L1 expression present AND Tumor Proportion Score (TPS) stated as low |
| XXX.4 | PD-L1 expression present AND Tumor Proportion Score (TPS) stated as high/positive |
| XXX.7 | Test ordered, results not in chart |
| XXX.8 | Not applicable: Information not collected for this case (If this item is required by your standard setter, use of code 8 will result in an edit error) |
