What Public CMS Data Show

These CMS figures cover limited populations and published records; they are not quality ratings or medical advice.

Nurse Practitioner: NPPES taxonomy is a reported classification, not proof of board certification.

30-day fills

47 standardized 30-day fills in 2020

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

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

Part D drug cost

$174 in 2020

The total cost of these prescriptions in 2020, paid by Medicare drug plans, patients and other payers together.

It shows the total spending on drugs this clinician prescribed, not what any one patient paid.

What this does not show

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.

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

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.

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.
