What this code means, what it should cost, and how to dispute an overcharge.
Fair Price Reference
What is CPT 95910?
Nerve conduction studies testing 7–8 nerves. NCS uses electrical impulses to measure how fast and strong signals travel through your nerves — diagnosing conditions like carpal tunnel syndrome, neuropathy, and radiculopathy.
Typical setting: Neurologist's office or hospital outpatient neurology lab.
What CPT 95910 should cost
The Centers for Medicare & Medicaid Services (CMS) pays approximately $133 for CPT 95910 under the 2025 Physician Fee Schedule. This is what the federal government has determined is a reasonable payment for this service.
Private insurance typically pays 1.2–1.8x Medicare rates ($160–$239). Hospital chargemaster prices for CPT 95910 often range from $300 to $1400 — a markup of 2.3x to 10.5x over Medicare.
Reality check: Medicare pays ~$133 for the professional component. Hospital-based NCS labs routinely charge $800–$1,400+ by stacking facility fees.
Common overcharges on CPT 95910
The NCS code tier (95907–95913) is based on the NUMBER of nerves tested. Providers frequently bill a higher tier than the number of nerves documented in the report. Request the report — count the nerves — and compare against the billed tier.
95860, 95885. Per CMS NCCI edits, these services are bundled.About Neurology billing
Nerve conduction studies (NCS) and electromyography (EMG) are among the most overcharged diagnostic tests. The combination study — NCS + needle EMG — is routinely billed at 5–10× Medicare rates, and improper unbundling of EMG components is extremely common.
Request the NCS/EMG report — it documents every nerve tested and every muscle needled. Count the nerves to verify the NCS code tier (95907–95913). Confirm that needle EMG add-on codes (95885/95886) have a qualifying primary NCS code on the same claim.
How to dispute a CPT 95910 overcharge
- Request the itemized bill. You are entitled to a detailed line-by-line bill showing every CPT code billed. Ask in writing.
- Compare to Medicare allowable. If the charge exceeds 150% of Medicare ($200), you have grounds to dispute.
- Request documentation. For E&M codes, ask for the visit note. For procedures, ask for the operative report. The documentation must justify the code billed.
- Send a formal dispute letter. Cite the specific discrepancy between the documentation and the code. Reference Medicare rates and NCCI edits where applicable.
- Follow up in writing. Give the provider 30 days to respond. If they don't, escalate to the state attorney general and insurance commissioner.
