Other mucopolysaccharidoses

This code identifies a group of rare, inherited metabolic disorders characterized by the body's inability to properly break down complex carbohydrates called glycosaminoglycans (GAGs). The accumulation of these GAGs in various tissues and organs leads to progressive cellular damage and a wide range of clinical manifestations affecting multiple body systems.

Use this code for patients diagnosed with a mucopolysaccharidosis that is not specifically classified elsewhere (e.g., Hurler, Hunter, Sanfilippo, Morquio, Maroteaux-Lamy, or Sly syndromes). Documentation should clearly state a diagnosis of a mucopolysaccharidosis, with further specificity ruled out or not yet determined.

• Ensure the physician documentation explicitly states "other mucopolysaccharidosis" or a specific type not otherwise classified.
• Avoid using this code if a more specific mucopolysaccharidosis (e.g., E76.0 for Hurler syndrome) is documented.
• Code any associated manifestations or complications (e.g., skeletal deformities, cardiac involvement) separately.
