ICD-10 Code D83.2 – Common variable immunodeficiency with autoantibodies to B- or T-cells (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D83.2 – Common variable immunodeficiency with autoantibodies to B- or T-cells
What it is
This code identifies a form of common variable immunodeficiency in which the immune system makes autoantibodies against B- or T-cells. It reflects an immune deficiency with autoimmune features, not a general infection code.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include recurrent infections, low immunoglobulin levels, and evidence of autoantibodies affecting B- or T-cell populations.
When to use this code
Use D83.2 when the provider documents common variable immunodeficiency specifically associated with autoantibodies to B- or T-cells. Code it when the diagnosis is confirmed or clearly stated in the record.
Choose this code only when the autoimmune component is documented, not for CVID alone. If the chart is unclear about the subtype, check documentation before assigning the code.
Do not use for
Do not use this code for unspecified common variable immunodeficiency or for other antibody deficiencies without the documented B- or T-cell autoantibodies. Check documentation.
Coding tip
Code the most specific CVID subtype documented, and verify that autoantibodies to B- or T-cells are explicitly stated.
