Other disorders of glucosaminoglycan metabolism

This code signifies rare metabolic conditions characterized by abnormal synthesis, degradation, or storage of glycosaminoglycans (GAGs) that do not fall into other specified categories. These disorders can lead to a wide range of systemic manifestations affecting skeletal, connective, and organ systems due to the accumulation of GAGs in tissues.

Apply this code when documentation specifies a disorder of GAG metabolism that is not a mucopolysaccharidosis (E76.0-E76.3) or a mucolipidosis (E76.5). This typically includes conditions like multiple sulfatase deficiency or other unclassified GAG storage diseases. Supporting documentation should clearly identify the specific GAG metabolism defect or the clinical diagnosis of an "other" specified GAG disorder.

• Do not use this code if a more specific code for mucopolysaccharidosis or mucolipidosis is available.
• Always review the medical record for precise diagnostic statements regarding the specific type of GAG metabolism disorder.
• Consider sequencing this code as a primary diagnosis when it is the main reason for the encounter, or as a secondary diagnosis when managing complications.
