Through program year 2025, Mary Maish of Lake Forest, IL is reported in the CMS Open Payments database as having received $60,576 across 106 general payments and $0 in research payments paid to them.

No combined total General, research and ownership are kept apart. Each is reported under its own rules, and ownership is not money that moved at all but the value of a stake held. A meal, a clinical trial grant and a shareholding do not add up to anything meaningful, so this site does not add them.

General payments for this record sit in the 91st percentile of Thoracic Surgery (Cardiothoracic Vascular Surgery) profiles with reported payments. Percentile describes the distribution, not the conduct.

Drug cost is what was paid for the drugs at the pharmacy — by Medicare, the patient and others — and is not money to the prescriber. Medicare Part D only: drugs dispensed to Medicare beneficiaries. A drug with fewer than 11 claims for this prescriber is not published, so a missing drug does not mean zero. The medians are for the 910 Part D prescribers listed as Thoracic Surgery; they describe a distribution and say nothing about conduct.

Payments and prescribing

3 products · payments 2024

Two separate records. The payments come from Open Payments and the claims from Medicare. They are set side by side because they name the same product; they do not show that a payment affected a prescription.

A dash means Medicare published no figure for this doctor and product — fewer than 11 claims, or the product is not covered under that part — which is not the same as none. Payments are general payments only; one that names several products is split evenly between them, so an amount is payments related to the product, not money paid for it.

What this means

U.S. law requires drug and medical device manufacturers to report payments and transfers of value they make to physicians and teaching hospitals. The Centers for Medicare & Medicaid Services publishes that record each year. This page shows what was reported about this person, and nothing else.

An ownership interest is different from the other two. It is not a payment: it is a stake — shares, options, a partnership holding — that a physician or an immediate family member held in a manufacturer during that year. The figure shown is what the stake was reported to be worth.

Research payments frequently pass through a clinician to the institution running a trial, and rarely represent personal income. They should be read differently from general payments.
