Medicare-allowed amount

About $1,623 in 2022

The total amount Medicare approved for these services in 2022. 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 $669 in 2022

The part of the Medicare-allowed amount that Medicare itself paid in 2022, 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 – by Provider and Service, 2022.

30-day fills

57 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

$1,494 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.

  • Novo Nordisk Inc: $225.94 across 2 records.

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.

Medicare assignment not listed

CMS data do not show whether this clinician accepts Medicare assignment. This does not mean they do not accept Medicare. Ask the office.

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; Medicare.gov, “Does your provider accept Medicare as full payment?”

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.

Enrolled in Medicare (PECOS)

Can order Medicare-covered services

CMS lists Stefan Hartmann as eligible to order or refer Medicare Part B clinical laboratory and imaging services, durable medical equipment (DME) and home health services for people with Medicare.

It does not mean the clinician offers these services directly.
