What Public CMS Data Show
General Practice: NPPES taxonomy is a reported classification, not proof of board certification.
Medicare-allowed amount
About $5,121 in 2019
The total amount Medicare approved for these services in 2019. 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.

Paid by Medicare
About $2,846 in 2019
The part of the Medicare-allowed amount that Medicare itself paid in 2019, 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

Source: CMS, Medicare Physician & Other Practitioners – by Provider and Service, 2019.
30-day fills
26 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: 30-day fills
It is not a count of patients and not a measure of quality.
Part D drug cost
$710 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: 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, 2020.
Industry payments (Open Payments)
Fewer than 11 payment records totaling $23.50 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.
It shows reported financial ties between this clinician and companies. You can ask your clinician about them.
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
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.

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?”
No telehealth indicator
CMS shows this indicator only when recent Medicare claims include telehealth services. The clinician may still offer telehealth; ask the office.

A physician who specializes in the general practice of diagnosing, treating, and managing patients with a variety of illnesses and conditions.
NUCC Taxonomy Code: 209800000X
Legal Medicine is a special field of medicine that focuses on various aspects of medicine and law. Historically, the practice of legal medicine made contributions to medicine as a scientific instrument to solve criminal perplexities. Since World War II, the domain of legal medicine has broadened to include not only aspects of medical science to solve legal and criminal problems but aspects of law as it applies to medicine. Legal Medicine continues to grow as medicolegal issues like medical malpractice and liability, government regulation of health care, issues of tort reform, and moral and ethical complexities presented by technological advances become increasingly prominent. Many medical schools have implemented courses which supply medicolegal instruction for medical students, and many law schools now offer medicolegal courses. Also, dual degree programs in law and medicine have been created to assist physicians to bridge the gap between medicine and the law.
