Secondary ID 
A test code used for billing and in test definitions created prior to November 2011
Useful For Suggests clinical disorders or settings where the test may be helpful
Diagnosis and management of patients with gastrointestinal stromal tumors or other related tumors
Identification of a mutation in exon 9 of the KIT gene
Additional Tests Lists test(s) that are always performed, at an additional charge, with the initial test(s)
| Test ID | Test Number | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|---|
| 20422 | 20422 | DNA/RNA Extraction, MAP Lab | No | Yes |
| 60254 | 60254 | AP Special Studies Review | No | Yes |
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
This test is performed in conjunction with 60254 Anatomic Pathology Special Studies Review and 20422 DNA/RNA Extraction, Molecular Anatomic Pathology Lab. The DNA/RNA extraction will only be charged once (unless all of the extracted DNA is used in initial testing and the Mayo Medical Laboratories client or Mayo Clinic attending physician requests additional tests, it is then appropriate to charge for a second extraction). Additional testing may be performed after review by pathologist. After review by the consultant, 60254 Anatomic Pathology Special Studies Review could be changed to 5439 Surgical Pathology Consultation, if they determine this is more appropriate.
