Based on Medicare claims data, Dr. Williams performed 1,200 contrast dye for imaging (iodine-based) services. These records cover Medicare fee-for-service activity, including eligible younger beneficiaries; they do not measure total practice volume or clinical quality.
Does Dr. Williams receive payments from pharmaceutical companies?
Yes. Dr. Williams received a total of $11,440 from 39 companies across 138 payment records. A record can group multiple payments. These transfers are publicly disclosed through CMS Open Payments. Disclosure alone does not establish their legality or effect on care. Patients may wish to ask their doctor about these relationships, especially if a recommended drug or device appears in the payment records.
How do Dr. Williams's costs compare to other radiology - diagnostics in O Fallon?
Dr. Williams's average Medicare payment per service is $38.

Procedure-level data above shows both what was submitted and what Medicare paid for each service type.
What does Data Coverage mean?
Data Coverage (currently Very High for Dr. Williams) measures how much public federal data is available about a provider. It is not a quality rating. A "Very High" or "High" level means the provider has data across multiple federal sources (NPPES, PECOS, Medicare Utilization, Open Payments), indicating the presence of registry, enrollment, activity or payment records, not verified experience or clinical quality. A "Low" or "Moderate" level may simply mean the provider is newer, does not see Medicare patients, or has not received any industry payments — none of which are inherently negative.

Source publication dates and the snapshots loaded on this site can differ. Rebuilding a page does not refresh its source records.
