Based on Medicare claims data, Dr. Dziuk performed 692 stereoscopic x-ray guidance for radiation therapy localization 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. Dziuk receive payments from pharmaceutical companies?
Yes. Dr. Dziuk received a total of $1,100 from 33 companies across 64 payment records. A record can group multiple payments. These transfers are publicly disclosed through CMS Open Payments.

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. Dziuk's costs compare to other radiology - diagnostics in San Antonio?
Dr. Dziuk's average Medicare payment per service is $156. Note that these figures represent what Medicare pays, not your out-of-pocket cost, which depends on your specific insurance plan and deductible. 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. Dziuk) 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.
