Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the E76 range.

Mucopolysaccharidoses

Group of lysosomal storage diseases each caused by an inherited deficiency of an enzyme involved in the degradation of glycosaminoglycans (mucopolysaccharides). The diseases are progressive and often display a wide spectrum of clinical severity within one enzyme deficiency.

About the E76 Code Range

The ICD-10 code section E76 covers disorders of glycosaminoglycan metabolism, including various types of mucopolysaccharidoses (MPS). These conditions are rare inherited metabolic diseases characterized by enzyme deficiencies affecting the breakdown of glycosaminoglycans.

Codes like E76.0 through E76.3 specify different mucopolysaccharidosis types. For example, E76.01 refers to Hurler's syndrome, also known as MPS-I-H or dysostosis multiplex, while E76.1 represents MPS-II, commonly called Hunter's syndrome. The section further categorizes variants including Morquio syndromes (codes E76.210 and E76.211) and Sanfilippo syndrome (E76.22). Specific distinctions among these codes help medical coders accurately identify the exact disorder, such as differentiating between Morquio A and B forms. Unspecified or other mucopolysaccharidoses and glucosaminoglycan metabolism disorders are captured under codes like E76.3 and E76.9. Using these codes correctly supports precise documentation and treatment planning for these complex metabolic diseases.
