Congenital hereditary muscular dystrophy

This code identifies a group of inherited disorders characterized by progressive muscle weakness and degeneration, present from birth or early childhood. These conditions result from genetic defects affecting muscle structure and function, leading to varying degrees of disability.

Apply this code for patients diagnosed with muscular dystrophy that is both congenital (present at birth) and hereditary (passed down genetically). Documentation should clearly indicate the onset of symptoms in infancy or early childhood and a familial history consistent with an inherited neuromuscular disorder.

• Differentiate from acquired muscular dystrophies or other myopathies with later onset.
• Consider additional codes for specific types of congenital muscular dystrophy if more detailed information is available (e.g., Ullrich, Fukuyama).
• Ensure physician documentation explicitly states "congenital" and "hereditary" or provides clinical details that unequivocally support both aspects.
