| ICD-10 from 2011 - 2016

E77.1 is a billable ICD code used to specify a diagnosis of defects in glycoprotein degradation. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code E771 is used to code Alpha-mannosidosis

Alpha-mannosidosis is a lysosomal storage disorder caused by deficient activity of the enzyme alpha-D-mannosidase. In humans it is known to be caused by an autosomal recessive genetic mutation. In livestock it is caused by chronic poisoning with swainsonine from locoweed.
