Post-Orchiectomy Lactate Dehydrogenase (LDH) Range


**Note 1**: Of the three tumor markers, lactate dehydrogenase (LDH) is the least specific for testicular cancer and is more of a determinant of bulky or disseminated disease. Although recommended to be tested, LDH may not be routinely performed, especially if the primary is localized. **Note 2**: Record the range of the LDH test as documented in the patient record after orchiectomy and prior to further treatment. **Note 3**: If the initial post-orchiectomy LDH test remains elevated, review the subsequent tests until normalization or plateau occurs and use that test to code this field. See Part I for further explanation of serum tumor marker half life. **Note 4**: If the post-orchiectomy LDH test is unknown but the preorchiectomy LDH test was normal, use code 990. **Note 5**: If the post-orchiectomy LDH test is unavailable but a physician's statement of the result is documented, use codes 991-993. **Note 6**: For rare cases that are treated prior to orchiectomy or an orchiectomy is not performed, code the initial LDH range in this field and not in CS Site-Specific Factor 10.
