Periodic paralysis
ICD-10 G72.3 is a billable code used to indicate a diagnosis of periodic paralysis.
Periodic paralysis is a rare neuromuscular disorder characterized by episodes of muscle weakness or paralysis that can last from minutes to days. It is often triggered by factors such as exercise, stress, or dietary changes. The condition can be associated with various underlying disorders, including myasthenia gravis, muscular dystrophies, myopathies, and neuromuscular junction disorders. In myasthenia gravis, for instance, the immune system attacks the communication between nerves and muscles, leading to weakness that may present as periodic paralysis. Muscular dystrophies, a group of genetic disorders, can also lead to muscle weakness and periodic episodes of paralysis due to muscle degeneration. Myopathies, which involve muscle inflammation or damage, can similarly manifest as periodic paralysis. Neuromuscular junction disorders, such as Lambert-Eaton syndrome, can cause muscle weakness that may be episodic in nature. Accurate diagnosis often requires a thorough clinical evaluation, including electromyography and blood tests, to identify the specific underlying condition contributing to the periodic paralysis.
Detailed history of symptoms, triggers, and diagnostic test results.
Patients presenting with episodic muscle weakness, particularly after physical exertion or stress.
Ensure that all episodes are documented, including duration and recovery time.
Thorough evaluation of metabolic factors that may contribute to periodic paralysis.
Patients with periodic paralysis associated with electrolyte imbalances or thyroid dysfunction.
Document any metabolic panels or hormone levels that may correlate with episodes.
Used to evaluate neuromuscular function in patients with periodic paralysis.
Document the reason for the EMG and findings related to muscle weakness.
Neurologists should ensure that the EMG results are clearly linked to the diagnosis.
Common triggers include strenuous exercise, high carbohydrate intake, stress, and electrolyte imbalances.
Diagnosis typically involves a detailed patient history, physical examination, and diagnostic tests such as serum electrolytes and electromyography.
