Chronic inflammatory demyelinating polyneuritis

This code represents a chronic, acquired, immune-mediated neuropathy characterized by progressive or relapsing weakness and sensory loss in more than one limb. It involves inflammation and demyelination of peripheral nerves, leading to impaired nerve conduction.

Assign this code for patients diagnosed with chronic inflammatory demyelinating polyneuropathy (CIDP) based on clinical presentation, electrodiagnostic studies (nerve conduction studies showing demyelination), and often nerve biopsy findings. It is appropriate for both newly diagnosed cases and ongoing management of the condition.

• Differentiate from acute inflammatory demyelinating polyneuropathy (Guillain-Barré syndrome) which has a more acute onset and different ICD-10-CM codes.
• Ensure documentation clearly specifies "chronic" or "relapsing-remitting" to support this specific code.
• Consider coding any associated manifestations or complications, such as muscle atrophy or gait disturbance, as secondary diagnoses.
