Medicare Profile & Education

Source: CMS Doctors and Clinicians National Downloadable File

Graduation Year

2018

30-day fills

19 standardized 30-day fills in 2018

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

$93 in 2018

The total cost of these prescriptions in 2018, 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.

Source: CMS, Medicare Part D Prescribers – by Provider and Drug, 2018.

Open Payments general payments, program year 2025

All general payments: $441.55 across 9 records.

By nature of payment

  • Food and Beverage: $441.55 across 9 records.

Reporting-company totals (3 largest of 4)

  • Teleflex LLC: $369.08 across 6 records.
  • Ethicon Inc.: $34.82 across 1 record.
  • Baxter Healthcare: $21.50 across 1 record.

A reported payment does not necessarily mean the financial relationship is improper and is not a measure of care quality. Clinicians can review and dispute these records.

Years since graduation

8 years (graduated 2018)

CMS Doctors and Clinicians data list 2018 as the year this clinician finished professional school.

What this does not show: Years since graduation

It is not the number of years in practice, and more years does not mean better care.

Source: CMS Doctors and Clinicians National Downloadable File.

NPI first issued

2018

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.

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.

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, β€œDoes 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.

Guide: How Medicare covers telehealth

Enrolled in Medicare (PECOS)

Dr. Mcelfresh 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. Mcelfresh 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.
