Challenges and Promise of Advanced Diagnostics 3 Nearly 30% of MDx claims paid incorrectly Lack of test specificity and identification makes it difficult to determine coverage or analyze what is being paid The MDx market is exploding, over 3000 MDx tests exist now Molecular Diagnostics (MDx) are rapidly growing: Diagnostics have significant downstream cost impact Tests and their processes are complex and the science is progressing rapidly Nearly 30% of MDx claims paid incorrectly 1 Lack of test specificity and identification makes it difficult to determine coverage or analyze what is being paid The number, type, and complexity of MDx tests are growing rapidly 10,000 2 and counting Impact Problem Cause Source: 1.

Tier 1 Codes are gene specific but not test specific  Example: is used for the following specific tests Alpha thalassemia targeted mutation analysis of HBA1 Alpha thalassemia targeted mutation analysis of HBA2 Alpha thalassemia sequence analysis of HBA1 Alpha thalassemia sequence analysis of HBA2 Alpha thalassemia known family-specific mutation analysis Tier 2 Codes are methodology specific but not test specific  Example: (Level 2) is used for these disparate tests (germline & somatic) Achondroplasia Mutation Analysis ColoVantage® (methylated Septin 9) Huntington Disease Mutation Analysis Mantle Cell Lymphoma, bcl-1/JHt(11;14), Real-time PCR, Cell based Need for Greater Granularity 4
