ICD10 code of Sly Syndrome and ICD9 code

Sly syndrome, also known as Mucopolysaccharidosis type VII (MPS VII), is identified by the ICD-10 code E76.29 (Other mucopolysaccharidoses) and the ICD-9 code 277.5 (Mucopolysaccharidosis). These classification codes are essential for medical billing, clinical documentation, and accessing specialized care for patients navigating this rare metabolic condition.

What is the clinical significance of Sly syndrome?

Sly syndrome is a rare lysosomal storage disorder caused by a deficiency of the enzyme beta-glucuronidase. Because this enzyme is necessary to break down complex sugar molecules called glycosaminoglycans (GAGs), their accumulation in various tissues leads to the multi-systemic symptoms characteristic of Sly syndrome. Clinical presentation is highly variable, ranging from severe neonatal hydrops fetalis to milder forms that may not be diagnosed until late childhood or adolescence.

How are ICD codes utilized for Sly syndrome?

Accurate coding is vital for patients with Sly syndrome to ensure proper insurance coverage for enzyme replacement therapy (ERT) and multidisciplinary support. Healthcare providers use these specific codes to track the prevalence of Sly syndrome and to facilitate the coordination of care across specialties including genetics, cardiology, and orthopedics.

What are the key clinical features of Sly syndrome?

The progression of Sly syndrome often involves a combination of skeletal, neurological, and physical manifestations. Common clinical findings include:

• Hepatosplenomegaly (enlarged liver and spleen)


• Skeletal abnormalities known as dysostosis multiplex


• Clouding of the cornea and retinal degeneration


• Developmental delay or cognitive impairment in certain phenotypes


• Distinctive coarse facial features and short stature

Next steps

• Consult with a board-certified clinical geneticist to confirm the diagnosis via enzyme assay or molecular genetic testing.


• Discuss the availability of Mepsevii (vestronidase alfa), an FDA-approved enzyme replacement therapy specifically for Sly syndrome.


• Connect with the Sly syndrome community at DiseaseMaps.org to share experiences and find emotional support.


• Request a referral to a metabolic center of excellence for comprehensive long-term management.
