Find information on Immunodeficiency Due to Conditions Classified Elsewhere, including clinical documentation requirements, medical coding guidelines, and healthcare resources. This page covers ICD-10 codes related to secondary immunodeficiency, immune deficiency documentation, differential diagnosis considerations, and managing immunodeficiencies caused by other conditions. Learn about diagnostic criteria, treatment implications, and best practices for documenting immunodeficiency secondary to other diseases for accurate coding and reimbursement.
Also known as
Disorders of the immune mechanism
Includes various immunodeficiencies like common variable immunodeficiency.
Human immunodeficiency virus [HIV] disease
Covers HIV infection, a major cause of acquired immunodeficiency.
Endocrine, nutritional and metabolic diseases
Certain conditions in this range can lead to secondary immunodeficiency.
Neoplasms
Cancers and related disorders can suppress the immune system.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the immunodeficiency due to a specific condition classified elsewhere?
Yes
Is it due to drug/medicinal effects?
No
Do not code D80-D89. The immunodeficiency is not due to a classified elsewhere condition. Review documentation for alternative diagnosis.

Coding D84.8 without documented underlying cause lacks specificity, impacting reimbursement and quality metrics. CDI crucial for clarification.
Misclassifying secondary immunodeficiencies (e.g., due to chemo) as D84.8 leads to inaccurate reporting and potential compliance issues.
Insufficient documentation linking the immunodeficiency to the underlying condition makes accurate D84.8 coding difficult, increasing audit risk. CDI can bridge the gap.
Patient presents with [signs and symptoms, e.g., recurrent infections, opportunistic infections, failure to thrive, chronic diarrhea] suggestive of immunodeficiency. Clinical evaluation reveals [specific findings, e.g., lymphadenopathy, hepatosplenomegaly, skin rashes, abnormal laboratory results such as low immunoglobulin levels, lymphopenia, or impaired lymphocyte function]. Based on the patient's history, physical examination, and laboratory findings, a diagnosis of Immunodeficiency Due to Conditions Classified Elsewhere is suspected. The underlying condition contributing to the immunodeficiency is identified as [specific underlying condition, e.g., malnutrition, protein-losing enteropathy, nephrotic syndrome, burns, malignancy, iatrogenic immunosuppression due to chemotherapy or radiation therapy, viral infection such as HIV]. Differential diagnoses considered include [list relevant differentials, e.g., primary immunodeficiency disorders, other secondary immunodeficiencies]. Further investigations may include [list planned investigations, e.g., specific immunological assays, genetic testing, imaging studies]. The patient's immunodeficiency severity is classified as [mild, moderate, or severe] based on [specific criteria, e.g., frequency and severity of infections, impact on growth and development]. Initial management plan includes [specific interventions, e.g., treatment of the underlying condition, prophylactic antibiotics, immunoglobulin replacement therapy, nutritional support, patient education regarding infection prevention strategies]. Patient education regarding the diagnosis, prognosis, and management plan was provided. Follow-up care with [relevant specialists, e.g., immunologist, infectious disease specialist, dietitian] is scheduled. ICD-10 code D84.89, Other specified immunodeficiencies, is documented for medical billing and coding purposes. Continued monitoring of immune function and overall health status is recommended.
