30-day fills

85 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

$447 in 2024

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

Industry payments (Open Payments)

Fewer than 11 payment records totaling $1,500.00 in 2024

Drug and medical device companies must report certain payments to doctors and some other clinicians to CMS, such as meals, travel, speaking fees or research funding.

These records are submitted by drug and medical device companies, and a reported payment does not necessarily mean the financial relationship is improper.

General: payments not tied to research, such as meals, travel, consulting or speaking fees.

A reported payment does not necessarily mean the financial relationship is improper. Research payments can go to a hospital or university for a study the clinician leads, not to the clinician personally. Clinicians can dispute records with the company that reported them.

NPI first issued

2019

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.

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.

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.

Enrolled in Medicare (PECOS)

Dr. Langdon 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. Langdon 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.
