ICD-10 Code D71.1 – Leukocyte adhesion deficiency (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D71.1 – Leukocyte adhesion deficiency
What it is
D71.1 identifies leukocyte adhesion deficiency, a rare inherited disorder where white blood cells cannot move normally to sites of infection. This causes impaired immune response and recurrent infections.
Clinical signs
Typical findings include recurrent bacterial infections, poor wound healing, and delayed separation of the umbilical cord in infancy. Clinical features vary; refer to documentation.
When to use this code
Use D71.1 when the clinician documents leukocyte adhesion deficiency or a confirmed diagnosis of this specific immunodeficiency. It may also apply when the record clearly states the inherited adhesion defect causing recurrent infections. If the note only says “immunodeficiency,” check documentation.
Do not use for
Do not use this code for general neutropenia, nonspecific recurrent infections, or other primary immunodeficiency disorders. Check documentation if the diagnosis is uncertain or not specifically named.
Coding tip
Code D71.1 only when the provider identifies leukocyte adhesion deficiency by name or equivalent confirmed wording.
