Common variable immunodeficiency, unspecified
ICD-10 D83.9 is a billable code used to indicate a diagnosis of common variable immunodeficiency, unspecified.
Common variable immunodeficiency (CVID) is a primary immunodeficiency disorder characterized by a significant reduction in serum immunoglobulin levels and an increased susceptibility to infections. Patients with CVID often experience recurrent bacterial infections, particularly of the respiratory and gastrointestinal tracts, due to impaired antibody production. The condition can also lead to autoimmune disorders, lymphoproliferative diseases, and an increased risk of malignancies. The etiology of CVID is heterogeneous, with both genetic and environmental factors contributing to its development. Diagnosis typically involves measuring serum immunoglobulin levels, assessing specific antibody responses, and ruling out other causes of hypogammaglobulinemia. The unspecified designation indicates that the specific subtype or underlying cause of the immunodeficiency has not been determined, which can complicate management and treatment strategies. Treatment often includes immunoglobulin replacement therapy and prophylactic antibiotics to prevent infections, along with monitoring for associated complications.
Detailed immunological testing results, treatment plans, and follow-up notes.
Patients presenting with recurrent infections, autoimmune symptoms, or family history of immunodeficiency.
Ensure clear documentation of immunoglobulin levels and response to therapy.
Complete blood counts, bone marrow biopsy results, and any hematological complications.
Patients with CVID presenting with cytopenias or lymphoproliferative disorders.
Document any hematological manifestations and their management.
Used for obtaining blood samples to measure immunoglobulin levels.
Document the reason for blood draw and any relevant clinical history.
Immunology specialists should ensure proper lab requisition forms are completed.
The unspecified designation indicates that the specific subtype or underlying cause of the common variable immunodeficiency has not been determined, which can affect treatment and management strategies.
