Facioscapulohumeral muscular dystrophy

This code represents a genetic, progressive muscle disorder primarily affecting the muscles of the face (facio-), shoulder blades (scapulo-), and upper arms (humeral). It is characterized by asymmetric weakness and atrophy, typically beginning in adolescence or early adulthood, and can lead to significant functional impairment.

This code is appropriate for patients diagnosed with facioscapulohumeral muscular dystrophy (FSHD) based on clinical presentation and genetic testing. Documentation should clearly state the diagnosis of FSHD, often including details about muscle weakness distribution and progression.

• Differentiate from other muscular dystrophies; ensure documentation specifically identifies FSHD.
• Consider sequencing this code as a primary diagnosis when FSHD is the reason for the encounter.
• Look for associated manifestations or complications, such as respiratory insufficiency or hearing loss, and code them separately.
