Amyotrophic lateral sclerosis

This code represents Amyotrophic Lateral Sclerosis (ALS), a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord. It leads to muscle weakness, atrophy, and eventually paralysis, impacting voluntary muscle control.

Use this code for patients diagnosed with ALS, also known as Lou Gehrig's disease. Documentation should clearly state the diagnosis of ALS, often supported by neurological examination findings, electromyography (EMG), and nerve conduction studies.

• Do not confuse with other motor neuron diseases unless specifically diagnosed as ALS.
• Sequence as a primary diagnosis when ALS is the reason for the encounter or as a secondary diagnosis when managing complications.
• Ensure documentation specifies "amyotrophic lateral sclerosis" to differentiate from other forms of motor neuron disease.
