ICD Code D72.818

ICD code D72.818 is used to indicate a diagnosis of other decreased white blood cell count, which means the patient has a lower than normal number of white blood cells for reasons not specified by other codes.

1. Laboratory results indicate a decreased white blood cell count that does not meet criteria for specific leukopenias such as neutropenia, lymphopenia, or agranulocytosis.

2. The patient presents with nonspecific symptoms potentially related to decreased immune function, such as recurrent or unusual infections, but without a definitive diagnosis of a specific white blood cell disorder.

3. The decreased white blood cell count is not attributable to chemotherapy, radiation, or other clearly defined causes that have their own specific codes.

4. The clinical context requires documentation of a decreased white blood cell count as a significant finding, but further classification is not possible based on available data.

5. The decreased white blood cell count is persistent or recurrent, and other causes have been ruled out or are not specified.
