Fluorescence in situ Hybridization (FISH), Oncology
CPT:
Contact CPT coding department at 800-222-7566, ext 6-8400.
Special Instructions
Call for additional probes not listed above. Pertinent clinical diagnosis, previous cytogenetic studies, and probe of interest should be included with the specimen (Call for a list of available probes or see online list.).
This test number is used for tracking oncology FISH specimens to the laboratory. Bill codes will be added when testing is complete, based on the processes performed in the laboratory.
Please provide targeted FISH probe and diagnosis. This test is essentially a tracking code, and the test will only be performed after the probes and diagnosis is provided. Absence of this information will delay turnaround time.
Expected Turnaround Time
3 - 5 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
