Neurology
95910 — Nerve conduction studies; 7-8 studies
This test measures how quickly electrical signals travel through 7 to 8 of your peripheral nerves by applying small electrical impulses to the skin.
- Typical setting: Neurologist's office, hospital outpatient
- National avg charge (illustrative): $200–$700 (varies by number of nerves tested and setting; typically billed with an EMG on the same visit)
- Most-disputed reason: Being charged for a higher-numbered NCS code (e.g., 95911 or 95912) than the actual number of studies performed — each motor or sensory nerve segment counts as one study, and the total count must be documented in the report.
What it means
What 95910 actually means
This test measures how quickly electrical signals travel through 7 to 8 of your peripheral nerves by applying small electrical impulses to the skin. It is used to diagnose nerve damage from conditions like carpal tunnel syndrome, diabetic neuropathy, or nerve injuries.
Common errors with this code
What goes wrong on real bills.
Most bills that look correct still contain at least one of these issues. Up to 49% of medical bills contain errors (CFPB).
- Being charged for a higher-numbered NCS code (e.g., 95911 or 95912) than the actual number of studies performed — each motor or sensory nerve segment counts as one study, and the total count must be documented in the report.
- NCS codes billed without a corresponding operative/test report documenting which nerves were tested — payers may audit and reduce payment if the documented study count does not match the billed code.
- Being billed for both NCS (nerve conduction study) and a separate 'EMG' (electromyography) without understanding these are two distinct tests — verify that your symptoms and the physician's orders justified both tests on the same visit.
If you see 95910 on your bill
Three steps before paying.
1. Get the itemized bill. If your statement only shows a summary, request the CPT-level itemized bill before paying. Generate the request language →
2. Cross-check against the EOB. Compare what your insurer's Explanation of Benefits says you owe versus what the hospital is asking. They disagree more often than people think. Read the bill-vs-EOB guide →
3. Run a free Bill Scan. Upload the bill (and EOB if you have it) and BillBusted will flag the most likely issues with this specific code in your specific state. Run free scan →
