B Symptoms


**Note 1:** Physician statement of B Symptoms can be used to code this data item when no other information is available. **Note 2:** Each stage should be classified as either A or B according to the absence or presence of defined constitutional symptoms, such as: * Fevers: Unexplained fever with temperature above 38 degrees C; * Night sweats: Drenching sweats that require change of bedclothes; * Weight loss: Unexplained weight loss of more than 10% of the usual body weight in the six months prior to diagnosis. **Note 3:** Pruritus alone does not qualify for B classification, nor does alcohol intolerance, fatigue, or a short, febrile illness associated with suspected infections. **Note 4:** Code 9 if there is no mention of B symptoms.
