Other immunodeficiencies
ICD-10 D84.89 is a billable code used to indicate a diagnosis of other immunodeficiencies.
D84.89 refers to a category of immunodeficiencies that do not fall under the more specific classifications of primary or secondary immunodeficiencies. These conditions can arise from various etiologies, including genetic mutations, environmental factors, or as a consequence of other diseases. Patients with D84.89 may present with recurrent infections, autoimmune disorders, or malignancies due to their compromised immune systems. The immunodeficiency can affect various components of the immune system, including humoral immunity, cell-mediated immunity, and innate immune responses. Clinicians must conduct thorough evaluations to identify the underlying causes, which may include hematologic disorders such as lymphoproliferative diseases or bone marrow pathologies. Treatment often involves managing infections, immunoglobulin replacement therapy, or addressing the underlying condition contributing to the immunodeficiency. Accurate coding is essential for proper reimbursement and to ensure that patients receive appropriate care.
Detailed history of hematologic conditions, laboratory results, and treatment plans.
Patients with unexplained recurrent infections or hematologic malignancies.
Ensure that all relevant lab results and clinical findings are documented to support the diagnosis.
Comprehensive immunological assessments, including specific antibody responses and T-cell function tests.
Patients presenting with autoimmune disorders or severe allergies alongside immunodeficiency.
Document any genetic testing or family history of immunodeficiency to clarify the diagnosis.
Used for laboratory tests to evaluate immune function.
Document the reason for blood draw and any relevant clinical history.
Ensure that the specialty performing the test is noted in the documentation.
D84.89 can be caused by genetic mutations, environmental factors, or secondary to other diseases such as malignancies or autoimmune disorders.
D84.89 is used when no more specific immunodeficiency code applies. It is essential to review the clinical documentation to identify the underlying cause.
