Frequently Asked Questions
Is Dr. Saniewski experienced with contrast dye for imaging (iodine-based)?
Based on Medicare claims data, Dr. Saniewski performed 3,350 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.
How do Dr. Saniewski's costs compare to other radiation oncologists in Avenel?
Dr. Saniewski's average Medicare payment per service is $15. 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 High for Dr. Saniewski) 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.
