Medicare-allowed amount

About $47,511 in 2024

The total amount Medicare approved for these services in 2024. 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.

Paid by Medicare

About $35,569 in 2024

The part of the Medicare-allowed amount that Medicare itself paid in 2024, 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.

30-day fills

3,915 standardized 30-day fills in 2024

CMS converts prescriptions to 30-day supplies so they can be compared. A 90-day prescription counts as about three 30-day fills.

What this does not show: 30-day fills

It is not a count of patients and not a measure of quality.

Part D drug cost

$140,712 in 2024

The total cost of these prescriptions in 2024, paid by Medicare drug plans, patients and other payers together.

What this does not show: Part D drug cost

A higher cost often reflects the type of medicines a specialty uses. It is not your out-of-pocket cost and not a measure of quality.

Years since graduation

23 years (graduated 2003)

CMS Doctors and Clinicians data list 2003 as the year this clinician finished professional school.

NPI first issued

2005

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.

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.

Guide: What Medicare assignment means

Telehealth (some services)

Recent Medicare claims show this clinician provided some services by telehealth, such as a video or phone visit.

What this does not show: Telehealth (some services)

It does not mean all services are offered by telehealth, or that telehealth is covered by your plan.
