30-day fills

41 standardized 30-day fills in 2022

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

$107 in 2022

The total cost of these prescriptions in 2022, 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.

Open Payments general payments, program year 2025

All general payments: $2,294.25 across 102 records.

  • Janssen Pharmaceuticals, Inc: $395.47 across 12 records.

A reported payment does not necessarily mean the financial relationship is improper and is not a measure of care quality. Clinicians can review and dispute these records.

Years since graduation

7 years (graduated 2019)

CMS Doctors and Clinicians data list 2019 as the year this clinician finished professional school.

What this does not show: Years since graduation

NPI first issued

2019

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.

Guide: What Medicare assignment means

Telehealth (some services)

Can order Medicare-covered services
