ICD-10 Code D83.8 – Other common variable immunodeficiencies (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D83.8 – Other common variable immunodeficiencies
What it is
D83.8 identifies other forms of common variable immunodeficiency that do not fit a more specific CVID category. Use it for documented antibody deficiency disorders when the record supports a common variable immunodeficiency pattern.
Clinical signs
Clinical features vary; refer to documentation. Common references describe recurrent infections, poor antibody response, and possible low immunoglobulin levels, but you should code only what is clearly documented.
When to use this code
Use D83.8 when the provider documents a CVID variant or another specified common variable immunodeficiency that is not captured by a more exact code. It may appear in specialist notes, problem lists, or discharge summaries. If the diagnosis is uncertain, check documentation before coding.
Do not use for
Do not use this code for isolated hypogammaglobulinemia or other immunodeficiencies that are documented separately. If the chart names a different primary immune disorder, choose the more specific code instead.
Coding tip
Code from the provider’s exact wording and confirm whether the record says CVID, a related subtype, or a different immunodeficiency.
