Understanding Febrile Neutropenia
Definition of Febrile Neutropenia
Febrile neutropenia is a medical emergency defined by the presence of fever, typically greater than 38.3°C (101°F), combined with neutropenia, a significant reduction in neutrophil count. Neutrophils are a type of white blood cell vital for fighting infections. When their levels drop below normal, patients become highly susceptible to bacterial and fungal infections.
Causes and Risk Factors
Febrile neutropenia primarily occurs among patients receiving chemotherapy for cancer, especially hematologic malignancies such as leukemia and lymphoma. Other causes include:
- Bone marrow suppression due to chemotherapy or radiation therapy
- Stem cell transplantation
- Certain medications that suppress immune function
- Infections that cause neutropenia
- Underlying immunodeficiency disorders
Risk factors increase the likelihood of developing febrile neutropenia and include high-dose chemotherapy, prolonged neutropenia duration, and pre-existing infections.
Clinical Significance
Rapid identification and treatment of febrile neutropenia are vital because the condition can rapidly progress to severe sepsis or septic shock. It is associated with increased morbidity, mortality, and healthcare costs. Therefore, accurate coding and documentation are essential for effective patient management and reporting.

ICD-10 Coding for Febrile Neutropenia
Overview of ICD-10 System
The International Classification of Diseases, Tenth Revision (ICD-10), is a standardized system used globally to classify diseases and health conditions. It provides specific codes to document diagnoses accurately for clinical, billing, and research purposes.
ICD-10 Code for Febrile Neutropenia
The primary ICD-10 code for febrile neutropenia is:
- D70.9 – Neutropenia, unspecified
However, specific coding for febrile neutropenia is often detailed by combining codes for neutropenia and fever, or through use of supplementary codes that specify the context.
Key codes include:
- D70.0 – Agranulocytosis
- D70.1 – Other neutropenia
- D70.8 – Other specified neutropenia
- D70.9 – Neutropenia, unspecified
- R50.9 – Fever, unspecified (used when fever is documented but not otherwise specified)
Note: When coding for febrile neutropenia specifically, healthcare providers often use a combination of codes:
- D70.9 (Neutropenia, unspecified)
- R50.9 (Fever, unspecified)
or, if more specific documentation exists:
- D70.8 (Other specified neutropenia)
- R50.81 – Fever presenting with neutropenia

Coding Guidelines and Best Practices
Documenting the Condition Accurately
Accurate documentation is crucial for correct coding. Clinicians should specify:
- Presence of neutropenia (with laboratory values)
- Presence of fever (with temperature readings)
- Underlying cause if known (e.g., chemotherapy, infection)
- Severity and duration of neutropenia
Using Combination Codes
While ICD-10 often requires combining codes to represent complex conditions, the guidelines recommend:
- Using the most specific code available
- Avoiding unspecified codes unless necessary
- Including additional codes for complications or underlying causes
Examples of Coding Scenarios
1. Patient with chemotherapy-induced febrile neutropenia:
- Code for neutropenia: D70.9 (Neutropenia, unspecified)
- Code for fever: R50.81 (Fever presenting with neutropenia)
- Additional codes for underlying disease or treatment as applicable
2. Patient with neutropenia due to infection:
- Code for neutropenia: D70.8
- Code for infection: based on the specific pathogen or site (e.g., Bacterial infection: A49.9)

Importance of Correct ICD-10 Coding in Febrile Neutropenia
Billing and Reimbursement
Correct coding ensures healthcare providers receive appropriate reimbursement for services rendered. Misclassification can lead to denied claims, reduced payments, or compliance issues.
Data Collection and Epidemiology
Accurate ICD-10 coding allows for reliable data collection, which is essential for understanding the prevalence, outcomes, and resource utilization associated with febrile neutropenia.
Quality of Care and Research
Proper documentation and coding facilitate quality improvement initiatives and clinical research by providing precise data on patient populations and treatment outcomes.

Additional Considerations
Use of Z-Codes
In some instances, Z-codes (for factors influencing health status) may be used to document underlying causes or circumstances influencing the condition, such as:
- Z51.11 – Chemotherapy session
- Z16.2 – Resistance to antimicrobial drugs
Coding in Different Settings
- Inpatient settings: More detailed coding is often necessary, including comorbidities and complications.
- Outpatient settings: Focus on the primary diagnosis and relevant codes for symptoms or underlying causes.
International Variations and Updates
While ICD-10 codes are standardized, some countries or healthcare systems may have slight variations or updates. Always consult the latest coding manuals or local guidelines.

Conclusion
Febrile neutropenia ICD 10 coding plays a vital role in ensuring precise diagnosis documentation, appropriate treatment, and accurate data collection. Healthcare providers must be familiar with the relevant codes, documentation requirements, and coding guidelines to optimize patient care, facilitate reimbursement, and contribute to epidemiological understanding. As medical practices evolve and new research emerges, staying updated with the latest coding standards ensures that febrile neutropenia is accurately represented in health records worldwide.

Frequently Asked Questions
What is the ICD-10 code for febrile neutropenia?
The ICD-10-CM code for febrile neutropenia is D70.9, which stands for 'Neutropenia, unspecified'. However, specific coding may vary depending on the clinical context, often requiring combination codes or additional documentation.
How is febrile neutropenia classified in ICD-10?
Febrile neutropenia is classified under codes related to neutropenia (D70.0–D70.9) combined with fever (R50.9). The most specific code often used is D70.9 for 'Neutropenia, unspecified', with additional coding for fever if documented.
Are there specific ICD-10 codes for chemotherapy-induced febrile neutropenia?
Yes, chemotherapy-induced febrile neutropenia can be coded using D70.0 for neutropenia with additional documentation indicating it is due to chemotherapy. Accurate coding depends on detailed clinical documentation.
What are the common ICD-10 codes associated with febrile neutropenia complications?
Common related ICD-10 codes include D70.9 for neutropenia, R50.9 for fever, and additional codes for infections or sepsis if present, such as A41.9 for sepsis, unspecified organism.
How can I differentiate between neutropenia and febrile neutropenia in ICD-10 coding?
Neutropenia is coded as D70.0–D70.9, while febrile neutropenia requires documentation of fever (R50.9) in addition to neutropenia. Often, a combination of codes is used to specify both conditions.
Is there a specific ICD-10 code for infectious complications of febrile neutropenia?
Infectious complications are coded separately, such as B95-B96 for bacterial infections, or A41.9 for sepsis, depending on the infection site and organism involved. The primary febrile neutropenia code remains D70.9.
What coding considerations are important for billing febrile neutropenia treatment?
Accurate documentation of neutropenia and fever is essential. Use D70.9 for neutropenia and R50.9 for fever, along with any infection codes. Additional codes for underlying conditions or causes, like chemotherapy, may be necessary.
How does the ICD-10 classification impact clinical documentation for febrile neutropenia?
Clear documentation specifying neutropenia and associated fever ensures accurate coding. Precise coding impacts reimbursement, epidemiological tracking, and patient care documentation.
Are there updates or changes in ICD-10 codes related to febrile neutropenia?
ICD-10 codes are periodically updated; however, as of now, D70.9 remains the primary code for unspecified neutropenia, with supplementary codes for fever and related infections. Always refer to the latest ICD-10-CM updates for accuracy.
Can febrile neutropenia be coded based solely on clinical suspicion without lab confirmation?
Coding should be based on documented diagnosis in the medical record. If febrile neutropenia is suspected but not confirmed, it is best to code the supporting diagnoses and document the clinical suspicion for accurate coding.
