ICD-10 Code D76 – Other specified diseases with participation of lymphoreticular and reticulohistiocytic tissue (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D76 – Other specified diseases with participation of lymphoreticular and reticulohistiocytic tissue
What it is
D76 is a broad ICD-10-CM category for uncommon disorders involving lymphoreticular and reticulohistiocytic tissue that do not fit a more specific code. Use it when the diagnosis is documented as an other specified condition in this group.
Clinical signs
Clinical features vary; refer to documentation. Findings may reflect involvement of reticuloendothelial or histiocytic tissue, but the record should name the specific disorder when possible.
When to use this code
Use D76 when the provider documents a specified disease of lymphoreticular or reticulohistiocytic tissue and no more precise ICD-10-CM code applies. It is appropriate for charted “other specified” conditions in this disease family. Check documentation for the exact diagnosis and any available subtype.
Do not use for
Do not use D76 if the record supports a more specific diagnosis code from the same chapter or another body system. Avoid it when the condition is unspecified or when documentation does not clearly identify lymphoreticular or reticulohistiocytic involvement.
Coding tip
Code the most specific documented disorder first; use D76 only when the provider’s wording leaves no better option.
