ICD-10 Code E75.02 – Tay-Sachs disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E75.02 – Tay-Sachs disease
What it is
E75.02 identifies Tay-Sachs disease, an inherited lysosomal storage disorder that causes harmful buildup of GM2 ganglioside. Use it when the record documents this specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include progressive neurologic decline, loss of developmental milestones, hypotonia, and vision or hearing impairment.
When to use this code
Use E75.02 when the clinician documents Tay-Sachs disease by name or clearly confirms GM2 gangliosidosis, Tay-Sachs type. It may appear in pediatric neurology, genetics, or metabolic disorder records. Code it from confirmed documentation, not from family history or carrier status alone.
Do not use for
Do not use this code for Tay-Sachs carrier status, family history, or other GM2 gangliosidoses unless Tay-Sachs disease is specifically documented. Check documentation if the record only says “lysosomal storage disorder.”
Coding tip
Confirm whether the provider documented the disease itself, because carrier screening and affected-disease coding are not the same.
