Medicare patients

16 people with Original Medicare in 2020

Different Original Medicare patients in 2020; counts below 11 are hidden; this does not show availability or quality.

Source: CMS, Medicare Physician & Other Practitioners โ€“ by Provider, 2020.

Medicare-allowed amount

About $1,946 in 2020

The total amount Medicare approved for these services in 2020. It includes what Medicare paid and what patients or their other insurance owed, such as the deductible and coinsurance.

What this does not show: Medicare-allowed amount

This is not the clinician's income. Part of it can go to a clinic or group practice, staff, equipment or drugs. It is not the price you will pay.

Source: CMS, Medicare Physician & Other Practitioners โ€“ by Provider and Service, 2020.

Paid by Medicare

About $1,561 in 2020

The part of the Medicare-allowed amount that Medicare itself paid in 2020, after patients' deductibles and coinsurance.

What this does not show: Paid by Medicare

This is not the clinician's income and not a measure of quality.

Source: CMS, Medicare Physician & Other Practitioners โ€“ by Provider and Service, 2020.

Industry payments (Open Payments)

Fewer than 11 payment records totaling $23.93 in 2025

Drug and medical device companies must report certain payments to doctors and some other clinicians to CMS, such as meals, travel, speaking fees or research funding.

These records are submitted by drug and medical device companies, and a reported payment does not necessarily mean the financial relationship is improper.

General: payments not tied to research, such as meals, travel, consulting or speaking fees.

A reported payment does not necessarily mean the financial relationship is improper. Research payments can go to a hospital or university for a study the clinician leads, not to the clinician personally. Clinicians can dispute records with the company that reported them.

Years since graduation

13 years (graduated 2013)

CMS Doctors and Clinicians data list 2013 as the year this clinician finished professional school.

What this does not show: Years since graduation

It is not the number of years in practice, and more years does not mean better care.

Source: CMS Doctors and Clinicians National Downloadable File, CMS release of October 2, 2026.

NPI first issued

2014

The year this clinician's National Provider Identifier (NPI) was issued. An NPI is a unique 10-digit ID that US health care providers use for billing.

What this does not show: NPI first issued

NPIs have been issued only since 2005, so this year is not necessarily when the clinician started practicing.

Source: CMS NPPES NPI Registry.

Accepts Medicare assignment

CMS data list this clinician as accepting Medicare assignment. This means agreeing to take the Medicare-approved amount as full payment for covered services.

Medicare assignment applies to Original Medicare. It does not tell you whether the clinician is in a Medicare Advantage plan's network, accepts other insurance, or is taking new patients.

Source: CMS Doctors and Clinicians, CMS release of October 2, 2026; Medicare.gov, โ€œDoes your provider accept Medicare as full payment?โ€

Guide: What Medicare assignment means

No telehealth indicator

CMS shows this indicator only when recent Medicare claims include telehealth services. The clinician may still offer telehealth; ask the office.
