The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) is a crucial system in medical diagnosis and coding. Within this system, each code represents a specific medical condition, symptom, or diagnosis. For professionals in healthcare and related fields, understanding these codes is paramount for accurate record-keeping, billing, and ultimately, patient care. One such code is D72.829, which refers to a specific condition related to white blood cell counts.

This code, D72.829, is officially designated as the Diagnosis Code For Leukocytosis, unspecified, or more plainly, Elevated white blood cell count, unspecified. It’s essential to understand what this means in a clinical context. Leukocytosis itself is not a disease but rather a condition characterized by an increase in the number of white blood cells (leukocytes) in the blood. These cells are a vital part of the immune system, fighting off infections and other diseases.
Within the ICD-10-CM system, code D72.829 falls under the category of “Other specified disorders of white blood cells”. It is a billable and specific code, meaning it is precise enough for reimbursement purposes. The code became effective on October 1, 2015, marking its inclusion in the non-draft ICD-10-CM for the year 2016. It is important to note that D72.829 is the American version of this ICD-10 code, and international versions might have slight variations.
Synonyms for D72.829 include simply “Leukocytosis” or “Leukocytosis (increase white blood cells in blood)”, highlighting the core meaning of the code. Clinically, leukocytosis is described as a “transient increase in the number of leukocytes in a body fluid”. This elevation is a sign that the body is responding to some form of stress, which could range from infection and inflammation to certain medications or underlying conditions.
While D72.829 specifies an elevated white blood cell count, it is termed “unspecified” because it doesn’t pinpoint the exact cause or type of leukocytosis. Further diagnostic evaluations are typically required to determine the underlying reason for the increased white blood cell count. This may involve additional blood tests to differentiate the types of white blood cells that are elevated (such as neutrophils, lymphocytes, eosinophils, basophils, or monocytes), as well as considering the patient’s symptoms, medical history, and other clinical findings.
In summary, diagnosis code D72.829 is a crucial entry point in the diagnostic process when an elevated white blood cell count is detected. It signals the presence of leukocytosis, prompting further investigation to identify the root cause and guide appropriate medical management. For accurate medical coding and billing, especially within the US healthcare system, understanding the specificity and application of ICD-10-CM code D72.829 is indispensable.
