LDH (Lactate Dehydrogenase) Post-Orchiectomy Range
Notes
**Note 1:** Physician statement of the LDH (Lactate Dehydrogenase) Post-Orchiectomy Range can be used to code this data item when there is no other information available. **Note 2:** Record the range of the LDH test as documented in the medical record **after orchiectomy** but prior to adjuvant therapy. The lab value may be documented in a lab report, history and physical, or clinical statement in the pathology report. **Note 3:** If the initial post-orchiectomy LDH remains elevated, review subsequent tests and record the lowest LDH value (normalization or plateau) prior to adjuvant therapy or before the value rises again. **Note 4:** Of the three tumor markers, lactate dehydrogenase (LDH) is the least specific for testicular cancer. The magnitude of LDH elevation directly correlates with Testis tumor burden. **Note 5:** If the pre-orchiectomy LDH was normal, a post-orchiectomy LDH may not be performed. In this case, code 5 should be recorded.| Code | Description |
|---|---|
| 0 | Within normal limits |
| 1 | Less than 1.5 x N (Less than 1.5 times the upper limit of normal for LDH) |
| 2 | 1.5 to 10 x N (Between 1.5 and 10 times the upper limit of normal for LDH) |
| 3 | Greater than 10 x N (Greater than 10 times the upper limit of normal for LDH) |
| 4 | Post-Orchiectomy lactate dehydrogenase (LDH) range stated to be elevated |
| 5 | Post-Orchiectomy lactate dehydrogenase (LDH) unknown or not done but pre-orchiectomy LDH was normal |
| 7 | Test ordered, results not in chart |
| 8 | Not applicable: Information not collected for this case (If this information is required by your standard setter, use of code 8 may result in an edit error.) |
| 9 | Not documented in medical record No orchiectomy performed LDH (Lactate Dehydrogenase) Post-Orchiectomy Range not assessed or unknown if assessed |
