ICD-10 Code D80.7 – Transient hypogammaglobulinemia of infancy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D80.7 – Transient hypogammaglobulinemia of infancy
What it is
Transient hypogammaglobulinemia of infancy is a temporary delay in normal antibody development during early childhood. It means the child has lower-than-expected immunoglobulin levels for age, but the condition usually improves over time.
Clinical signs
Clinical features vary; refer to documentation. Common references describe recurrent minor infections, delayed maturation of immunoglobulin levels, and otherwise normal immune development. Diagnosis is generally made after evaluation excludes more persistent immunodeficiency.
When to use this code
Use D80.7 when the record specifically documents transient hypogammaglobulinemia of infancy or an equivalent diagnosis. It is appropriate for pediatric encounters where the provider notes temporary low immunoglobulins with expected recovery. Check documentation if the chart only says “low IgG” or “immunodeficiency.”
Do not use for
Do not use this code for unspecified hypogammaglobulinemia, congenital immunodeficiency, or other primary antibody disorders unless the provider clearly states transient hypogammaglobulinemia of infancy. Check documentation for the exact diagnosis.
Coding tip
Code only when the provider links the finding to this specific transient condition, not when low immunoglobulins are noted alone.
