ICD Code C85.90

ICD code C85.90 is used to classify a diagnosis of non-Hodgkin lymphoma when the specific type and site of the lymphoma are not specified. This code is typically used when the healthcare provider has identified the presence of non-Hodgkin lymphoma but lacks detailed information about its subtype or the exact location in the body. This code helps in the documentation and billing processes by providing a standardized way to record this diagnosis in medical records and insurance claims.

1. Presence of Lymphadenopathy: Swelling of lymph nodes that is persistent and unexplained, often found in the neck, armpits, or groin.

2. Unexplained Weight Loss: Significant and unintended weight loss over a short period, typically more than 10% of body weight within six months.

3. Fever: Recurrent fevers that are not attributed to infections or other identifiable causes.

4. Night Sweats: Profuse sweating during the night that may require changing bedclothes, not related to environmental factors.

5. Fatigue: Persistent and unexplained fatigue that does not improve with rest and affects daily activities.

6. Itching (Pruritus): Generalized itching without an apparent rash or skin condition.

7. Abdominal Pain or Swelling: Discomfort or swelling in the abdomen due to enlarged lymph nodes or organs such as the spleen or liver.

8. Chest Pain or Breathing Difficulties: Symptoms such as chest pain, coughing, or difficulty breathing, potentially due to enlarged lymph nodes in the chest area.

9. Blood Test Abnormalities: Abnormal results in blood tests, such as low red blood cell count (anemia), low white blood cell count (leukopenia), or low platelet count (thrombocytopenia).

10. Biopsy Confirmation: Histological confirmation of lymphoma through a biopsy of affected tissue, showing the presence of malignant lymphocytes.

11. Imaging Studies: Evidence from imaging studies such as CT, MRI, or PET scans showing masses or enlarged lymph nodes consistent with lymphoma.

12. Bone Marrow Involvement: Detection of lymphoma cells in the bone marrow through a bone marrow biopsy.

These criteria and symptoms should be evaluated by healthcare professionals to determine the appropriate use of the ICD code for diagnostic and billing purposes.
