142 Medicare services, 2024 (ranked within specialty)
Medicare volume is ranked against active providers in the same specialty. Signals a provider has no public data for (e.g. Medicare claims) are left out of the score entirely — never counted as zero — so providers without that data are not penalized. See the full formula and weights in our methodology.
What this provider does (Medicare)
Based on Medicare fee-for-service claims, 2024; not all care is captured.
| Service (HCPCS) | Medicare services | Typical Medicare-allowed (2024) |
|---|---|---|
| Needle Measurement of Electrical Activity in Muscle, Including Jitter, Blocking And/Or Fiber Density95872 | 48 | $203 |
| Testing of Nerve-Muscle Junction95937 | 31 | $118 |
| Needle Measurement of Electrical Activity in Arm Or Leg Muscles, Complete Study95886 | 27 | $108 |
| Needle Measurement of Electrical Activity in Trunk Or Head Muscles95887 | 22 | $93 |
| Nerve Conduction, 1-2 Studies95907 | 14 | $99 |
Typical Medicare-allowed amounts for these services range $93–$203 (2024). The Medicare-allowed amount is what Medicare recognizes for a service under fee-for-service — a reference figure for 2024, not a price quote and not what you would be billed. Medicare Part B covers roughly an eighth of all NPIs (65+ skew); services with fewer than 11 beneficiaries are suppressed by CMS.
