ICD Code D72.819

ICD code D72.819 is used to indicate a condition where there is a lower than normal count of white blood cells in the blood, but the specific type or cause of the decrease is not specified. This code is often used when the healthcare provider has identified a reduction in white blood cells but has not determined the underlying reason or type of white blood cell affected.

1. Routine Blood Tests: Use the ICD code when a routine complete blood count (CBC) test reveals a decreased white blood cell count without a specific diagnosis.

2. Infection Symptoms: When a patient presents with symptoms such as fever, chills, or recurrent infections, and blood tests confirm a decreased white blood cell count.

3. Fatigue and Weakness: If a patient reports unexplained fatigue or weakness, and subsequent blood work indicates a decreased white blood cell count.

4. Unexplained Weight Loss: In cases where a patient experiences significant, unexplained weight loss, and laboratory results show a decreased white blood cell count.

5. Bleeding or Bruising: When a patient exhibits unusual bleeding or bruising, and a CBC reveals a decreased white blood cell count.

6. Chronic Illness Monitoring: For patients with chronic illnesses where regular monitoring of blood cell counts is necessary, and a decrease in white blood cells is observed.

7. Post-Treatment Evaluation: After treatments such as chemotherapy or radiation therapy, if a decreased white blood cell count is detected during follow-up blood tests.

8. Autoimmune Disorders: When evaluating patients with suspected or diagnosed autoimmune disorders, and a decreased white blood cell count is part of the clinical picture.

9. Exposure to Toxins: In cases where a patient has been exposed to certain chemicals or toxins, and blood tests show a decreased white blood cell count.

10. Nutritional Deficiencies: When investigating potential nutritional deficiencies, such as vitamin B12 or folate deficiency, that may result in a decreased white blood cell count.

For the ICD code D72.819, which pertains to a decreased white blood cell count, unspecified, the relevant CPT codes that may be applicable for treatment or diagnostic purposes include:

1. 85025 - Complete blood count (CBC) with automated differential white blood cell count.
2. 85027 - Complete blood count (CBC), automated (Hgb, Hct, RBC, WBC, and platelet count).
3. 85048 - Leukocyte (WBC), automated count.
4. 85049 - Automated differential white blood cell count.
5. 85007 - Blood count; blood smear, microscopic examination with manual differential WBC count.

These CPT codes are typically used for laboratory tests that help in diagnosing and monitoring conditions related to white blood cell counts. It's important for healthcare providers to select the appropriate CPT code based on the specific services rendered and the clinical context.
