Years since graduation
5 years (graduated 2021)
CMS Doctors and Clinicians data list 2021 as the year this clinician finished professional school.

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.

May accept Medicare assignment
CMS data show this clinician may accept Medicare assignment. Clinicians who do not always accept assignment can decide case by case.
Ask the office before your visit. If a clinician does not accept assignment for a service, they can charge up to 15% more than the Medicare-approved amount, and you may be asked to pay the full amount at the visit.
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.

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)
Dr. Koller has a Medicare enrollment record in PECOS, the CMS system clinicians use to enroll so they can bill Medicare or order services for people with Medicare.

Can order Medicare-covered services
CMS lists Dr. Koller 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.
Medicare pays for these items and services only when they are ordered by an eligible clinician.
What this does not show: Can order Medicare-covered services
It does not mean the clinician offers these services directly.
