ICD-10 Code E75.10 – Unspecified gangliosidosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E75.10 – Unspecified gangliosidosis
What it is
E75.10 identifies gangliosidosis when the specific subtype is not documented. It refers to a lysosomal storage disorder involving abnormal ganglioside accumulation, but the exact form is not named in the record.
Clinical signs
Clinical features vary; refer to documentation. Typical references describe progressive neurologic decline, developmental delay, hypotonia, and organ involvement, but you should code only what is clearly supported in the chart.
When to use this code
Use this code when the provider documents gangliosidosis without specifying GM1, GM2, or another subtype. It is appropriate for confirmed cases where the record remains nonspecific after evaluation. If later notes identify a more precise diagnosis, update the code accordingly.
Do not use for
Do not use E75.10 when the subtype is documented, such as a specific GM1 or GM2 gangliosidosis. Also avoid it if the diagnosis is only suspected or if the record names a different metabolic disorder. Check documentation.
Coding tip
Query the provider for the exact gangliosidosis type before assigning an unspecified code.
