How do Dr. Chan's costs compare to other radiation oncologists in Mchenry?
Dr. Chan's average Medicare payment per service is $35.

What does Data Coverage mean?
Data Coverage (currently Very High for Dr. Chan) 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.
