White Blood Cell Count
Notes
**Note 1:** This SSDI is effective for diagnosis years 2024+
* For cases diagnosed 2018-2023, leave this SSDI blank
**Note 2:** Physician statement of WBC (White Blood Cell Count) Pretreatment Lab Value can be used to code this data item when no other information is available.
* Record the lab value of the highest WBC test result documented in the medical record **prior to treatment**. The lab value may be recorded in a lab report, history and physical, or clinical statement in the pathology report
* Record to the nearest cells per microliter (cells/uL) the highest WBC lab value documented in the medical record **prior to treatment**.
* A known lab value takes priority over codes XXXXX.2-XXXXX.4
- The lab value takes priority even if the physician documents the interpretation
*Example:* Patient noted to have a WBC count of 60,000. Physician notes that the value is elevated.
Code 60,000 instead of XXXXX.4 (elevated)
**Note 3:** The most common measurement of white blood cells is cells/mm3. If your facility has a different measurement, here are the conversions
* ***Example:*** 4250 cells/mm3
* Kul: 4.25 (divide cells/mm3 by 1000)
* 10^3/ul: 4.25 (divide cells/mm3 by 1000)
* K/mm3: 4.25 (divide cells/mm3 by 1000)
* cells/uL: 4250 (same as cells/mm3)
