Common overcharges on CPT 95911
Billing limited EMG (95885) without the required nerve conduction study primary code. Billing both a limited and complete EMG on the same extremity. Billing EEG with activation (95819) alongside a standard EEG (95816) for the same session. Over-reporting the number of nerve studies performed to bill a higher-tier NCS code.
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 95911 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 ($239), 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.
