        Description
            Thrombocytopenia is defined by a deficiency of platelets in the blood. In staging of Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL), thrombocytopenia is defined as Platelets (Plt) less than 100,000/μL.
        Rationale
                Thrombocytopenia is a prognostic factor required for staging of Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL) in AJCC 8th edition, Chapter 79 _Hodgkin and Non-Hodgkin Lymphomas_.
            Codes
                | 0 | Thrombocytopenia not present Platelets (Plt) = 100,000/µL Physician states Rai Stage 0-III | 
| 1 | Thrombocytopenia present Platelets (Plt) \< 100,000/µL | 
| 5 | Not applicable: Primary site is not C421 | 
| 6 | Lab value unknown, physician states thrombocytopenia is present Physician states Rai Stage IV | 
| 7 | Test ordered, results not in chart | 
| 9 | Not documented in medical record Thrombocytopenia not assessed or unknown if assessed No Rai stage is documented in the record and there is no documentation of thrombocytopenia |
