ICD Code G61.81

ICD code G61.81 is chronic inflammatory demyelinating polyneuritis, a long-term neurological disorder where the body’s immune system attacks the nerves, causing weakness, numbness, and impaired motor function.

1. Progressive or relapsing motor and sensory dysfunction in more than one limb

2. Symptoms persisting for at least 8 weeks

3. Symmetrical weakness of both proximal and distal muscles

4. Reduced or absent deep tendon reflexes

5. Electrophysiological evidence of demyelination on nerve conduction studies

6. Elevated cerebrospinal fluid (CSF) protein with normal cell count

7. Exclusion of other causes of neuropathy (e.g., diabetes, toxins, hereditary neuropathies)

8. Possible sensory ataxia, paresthesia, or numbness

Relevant CPT codes that may be used to treat ICD code G61.81 include:

- 96365: Intravenous infusion, for therapy, prophylaxis, or diagnosis; initial, up to 1 hour

- 36415: Collection of venous blood by venipuncture

- 95860: Needle electromyography; one extremity with or without related paraspinal areas

- 95861: Needle electromyography; two extremities with or without related paraspinal areas

- 95886: Needle electromyography, each extremity, with related paraspinal areas, when performed, done with nerve conduction, amplitude and latency/velocity study

- 97110: Therapeutic exercises to develop strength and endurance, range of motion and flexibility, each 15 minutes

- 97112: Neuromuscular reeducation of movement, balance, coordination, kinesthetic sense, posture, and/or proprioception for sitting and/or standing activities, each 15 minutes

These CPT codes are commonly associated with the management and treatment of G61.81. Always verify payer-specific guidelines and documentation requirements.
