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) |
|---|---|---|
| Office Or Other Outpatient Visit for the Evaluation and Management of an Established Patient That Requires the Supervision of a Physician Or Other Qualified Health Care Professional and Provision of Greater Than 56 Mg Esketamine Nasal Self-Administration,G2083 | 113 | $1,054 |
Typical Medicare-allowed amounts for these services range $1,054–$1,054 (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.
