What Public CMS Data Show

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

Physician Assistant: NPPES taxonomy is a reported classification, not proof of board certification.

Medicare-allowed amount

About $1,433 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.

It shows the total cost of this clinician's Original Medicare services under Medicare's fee rules.

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 – by Provider and Service, 2022.

Paid by Medicare

About $1,084 in 2022

The part of the Medicare-allowed amount that Medicare itself paid in 2022, after patients' deductibles and coinsurance.

The gap between the allowed amount and this number is roughly what patients and their other insurance paid.

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

3,744 standardized 30-day fills in 2024

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

$782,366 in 2024

The total cost of these prescriptions in 2024, 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: 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, 2024.

Open Payments general payments, program year 2025

All general payments: $1,234.05 across 64 records.

By nature of payment

  • Education: $34.00 across 1 record.

  • GlaxoSmithKline, LLC.: $217.56 across 18 records.

Years since graduation

35 years (graduated 1991)

CMS Doctors and Clinicians data list 1991 as the year this clinician finished professional school.

It tells you roughly how long ago the clinician finished 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

2006

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.

With Original Medicare, you usually pay only your deductible and coinsurance, and the office sends the claim to Medicare for you.

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.

Guide: How Medicare covers telehealth

Enrolled in Medicare (PECOS)

John Gordon 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.

Source: CMS Medicare Fee-For-Service Public Provider Enrollment (PECOS); CMS Order and Referring file.

Guide: What Medicare enrollment (PECOS) means

Can order Medicare-covered services

CMS lists John Gordon 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.
