Jill Mazza, M.D.

The practice location on the claims changed between years. The specialty on the claims is the same in every year.

From the provider fields of each year's CMS Medicare Physician & Other Practitioners file (the location and specialty on the claims, as CMS publishes them).

For 2024, a Physician Report would place Jill Mazza, M.D. in a peer group of 287 Otolaryngology clinicians, Jill Mazza, M.D. included, at the metro level (Los Angeles-Long Beach-Anaheim, CA).

Peers are clinicians with the same specialty on their claims, in the first of the metro area, the state and the nation that has enough of them. The sizes for every year are in the table under Available data.

This page comes from public files the Centers for Medicare & Medicaid Services publishes each year: the Medicare Physician & Other Practitioners files, which list the Part B services each clinician billed to Original Medicare, and the Doctors and Clinicians files, which list group and hospital affiliations. It covers Original Medicare fee-for-service only: Medicare Advantage, Medicaid and commercial insurance are not in these files, and CMS leaves out any service line with fewer than 11 beneficiaries. The location and specialty are what the claims show, and affiliations are as of the snapshot date, so either can lag a recent change. A listing here says nothing about quality of care.
