Medicare patients

42 people with Original Medicare in 2024

Different Original Medicare patients in 2024; counts below 11 are hidden; this does not show availability or quality.

Source: CMS, Medicare Physician & Other Practitioners โ€“ by Provider, 2024.

Medicare-allowed amount

About $2,400 in 2024

The total amount Medicare approved for these services in 2024. 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.

Source: CMS, Medicare Physician & Other Practitioners โ€“ by Provider and Service, 2024.

Paid by Medicare

About $1,646 in 2024

The part of the Medicare-allowed amount that Medicare itself paid in 2024, 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.

30-day fills

13 standardized 30-day fills in 2014

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

$159 in 2014

The total cost of these prescriptions in 2014, 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.

Years since graduation

16 years (graduated 2010)

CMS Doctors and Clinicians data list 2010 as the year this clinician finished professional school.

What this does not show: Years since graduation

NPI first issued

2010

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.

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.

Source: CMS Doctors and Clinicians; Medicare.gov, โ€œDoes your provider accept Medicare as full payment?โ€

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)

Dr. Mitchell 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.

It does not show whether the clinician accepts assignment, is in your plan's network, or is taking new patients.

Guide: What Medicare enrollment (PECOS) means

Can order Medicare-covered services

CMS lists Dr. Mitchell 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.

What this does not show: Can order Medicare-covered services

It does not mean the clinician offers these services directly.
