What the payments were

Each payment as the manufacturer categorized it when reporting it to CMS, across 2019–2025. Together they are the general payments above. A category is the reporter’s, and nothing in the record says a payment in any of them was improper.

By program year

CMS reports a program year at a time and also publishes its own total across them, which is what the figures above are. These rows are that total taken apart, not a second set of payments.

CMS’s file covers 2019–2025. It holds no payments to Michael Xiong in 2019 and 2022–2023.

The state of the license CMS lists first.

Recipient type

Covered Recipient Physician

How CMS classifies the recipient of these payments.

Medicare prescribing

What this provider billed to Medicare Part D in 2024, as CMS published it. Medicare Part D only: what they prescribed outside it is not here.

174

Claims

Prescriptions and refills billed to Part D, as CMS counts them.

$2,283

Total drug cost

What Part D, the plan and the patient paid together. Not what this provider was paid — they are paid nothing out of it.

127

Beneficiaries

People with at least one prescription from this provider.

Withheld

Brand-name claims

Of the claims above, those for a brand-name drug. CMS withheld this value and marked it "*". It publishes two markers and two reasons — a value between 1 and 10, or one withheld so another cannot be worked out — without saying which marker means which.

172

Generic claims

Of the claims above, those for a generic.

not reported

Opioid claims

Claims for an opioid. CMS published no figure for this provider, and there is no suppression marker on this measure — so this is an absent figure rather than a withheld one, and it is not a zero.

127

Antibiotic claims

Claims for an antibiotic.

Dermatology

Prescriber type

As CMS classifies this prescriber. Credentials: MD.

A blank is not a zero. CMS withholds a value between 1 and 10, and withholds the next lowest alongside it so the first cannot be worked out by subtraction — so a withheld figure is not even evidence that the number was small. Rows for ten or fewer claims are removed from the file altogether, which is why the parts of a total can be withheld while the total is published.
