30-day fills

13 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

$37 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.

Open Payments general payments, program year 2025

All general payments: $93.99 across 3 records.

By nature of payment

  • AXOGEN: $35.03 across 1 record.
  • ABBVIE INC.: $31.28 across 1 record.

Years since graduation

5 years (graduated 2021)

CMS Doctors and Clinicians data list 2021 as the year this clinician finished professional school.

What this does not show: Years since graduation

NPI first issued

2021

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

No telehealth indicator

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