Leukocytosis is a medical condition that occurs when there is an increase in the number of white blood cells (leukocytes) in the blood. It is a common finding in many medical conditions, including infections, inflammation, and cancer. The International Classification of Diseases (ICD) is a standardized system for coding medical diagnoses and procedures.
What is ICD-10?
ICD-10 is the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD), which is a medical classification system used by healthcare providers worldwide. ICD-10 is used to classify and code diagnoses, symptoms, and procedures for medical billing and statistical purposes.
What is Leukocytosis?
Leukocytosis is a medical condition that occurs when there is an increase in the number of white blood cells (leukocytes) in the blood. The normal range of white blood cells in the blood is between 4,500 and 11,000 cells per microliter (mcL) of blood. When the number of white blood cells exceeds this range, it is called leukocytosis.
Causes of Leukocytosis Leukocytosis can be caused by many medical conditions, including:
- Infections: Bacterial, viral, and fungal infections can cause leukocytosis.
- Inflammation: Inflammatory conditions, such as rheumatoid arthritis, can cause leukocytosis.
- Cancer: Some types of cancer, such as leukemia and lymphoma, can cause leukocytosis.
- Medications: Certain medications, such as corticosteroids, can cause leukocytosis.
ICD-10 Code for Leukocytosis The ICD-10 code for leukocytosis is R79.89. This code falls under Chapter 18 of the ICD-10, which deals with “Symptoms, signs, and abnormal clinical and laboratory findings, not elsewhere classified.”
The code R79.89 is used to classify and code leukocytosis when it is not due to a specific medical condition. If leukocytosis is due to a specific medical condition, the code for that condition should be used instead.
For example, if leukocytosis is due to a bacterial infection, the code for bacterial infection should be used. If leukocytosis is due to a medication, the code for adverse effects of that medication should be used.
It is important to use the correct ICD-10 code for leukocytosis to ensure accurate medical billing and statistical analysis.
