CS Site-Specific Factor 12
HER2: Chromogenic In Situ Hybridization (CISH) Lab Value
Notes
**Note 1**: Record the results of only the Chromogenic In Situ Hybridization (CISH) test for Human Epidermal Growth Factor Receptor 2 (HER2) in this field. The test determines whether there are additional copies of the HER2/neu gene in the tumor cells. The results are reported as the mean number of copies of the HER2/neu gene on either 30 or 60 tumor cells. **Note 2**: Record the actual mean if given. Enter the stated mean to two decimal places. Use a trailing zero if needed. **Note 3**: The same laboratory test should be used to record information in CS Site-Specific Factors 12 and 13. **Note 4**: If the test is done but the actual mean is not stated, use code 997. **Note 5**: If the test is not mentioned in the medical record, code to 999 unless there are circumstances under which the test isn't performed, for example, no histologic specimen.Default
