Sulfatase deficiency

This code identifies a rare, inherited metabolic disorder characterized by the deficiency of the enzyme sulfatase. This deficiency leads to the accumulation of sulfated compounds in various tissues, causing progressive neurological deterioration, developmental delay, and other systemic symptoms. The most common form is metachromatic leukodystrophy (MLD).

Assign this code for patients diagnosed with any form of sulfatase deficiency, including metachromatic leukodystrophy (MLD), multiple sulfatase deficiency (MSD), or other specific sulfatase enzyme deficiencies. Documentation should clearly state the diagnosis of sulfatase deficiency, often confirmed by enzyme assays or genetic testing.

• Ensure the medical record specifies a confirmed diagnosis of sulfatase deficiency, not just suspected or rule-out.
• Consider additional codes for specific manifestations or complications of the disease, such as neurological impairments or developmental delays.
• Do not confuse with other lysosomal storage disorders unless sulfatase deficiency is explicitly documented.
