Other immunodeficiencies
Chapter 3:Diseases of the blood and blood-forming organs
ICD-10 D84 is a billable code used to indicate a diagnosis of other immunodeficiencies.
D84 encompasses a variety of immunodeficiency disorders that do not fall under the more specific categories of primary or secondary immunodeficiencies. These conditions can result from genetic defects, environmental factors, or other underlying health issues that compromise the immune system's ability to function effectively. Patients with D84 may experience recurrent infections, autoimmune disorders, or malignancies due to their impaired immune response. The classification includes conditions such as common variable immunodeficiency (CVID), specific antibody deficiency, and other rare syndromes that lead to inadequate immune function. Diagnosis often involves a combination of clinical evaluation, laboratory tests to assess immune function, and genetic testing. Management may include immunoglobulin replacement therapy, prophylactic antibiotics, and treatment of associated complications, making it essential for coders to understand the nuances of each patient's condition and treatment plan.
Detailed immunological assessment results, patient history, and treatment plans.
Patients presenting with recurrent infections, autoimmune disorders, or unexplained lymphadenopathy.
Ensure that all laboratory tests and clinical evaluations are documented to support the diagnosis.
Complete blood counts, bone marrow biopsy results, and any relevant genetic testing.
Patients with hematologic malignancies or cytopenias associated with immunodeficiency.
Document any co-existing hematologic conditions that may complicate the immunodeficiency.
Used for laboratory tests to assess immune function.
Document the reason for blood draw and any relevant clinical history.
Ensure that the specialty performing the test is noted.
D84 includes a variety of immunodeficiencies that do not fall under more specific categories, such as common variable immunodeficiency and specific antibody deficiency.
Accurate coding for D84 requires detailed documentation of the patient's clinical history, laboratory results, and treatment plans to support the diagnosis.
