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.

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) |
|---|---|---|
| Comprehensive Hearing and Speech Recognition Test92557 | 161 | $36 |
| Test to Assess Middle Ear Function92567 | 114 | $16 |
| Test for Eardrum and Muscle Function92550 | 73 | $22 |
| Test for Hearing Various Pitches Using Earphone and Device Placed Against the Bone92553 | 46 | $47 |
Typical Medicare-allowed amounts for these services range $16–$47 (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.
