Frequently Asked Questions
Is Dr. Ference experienced with chest x-ray, 2 views?
Based on Medicare claims data, Dr. Ference performed 471 chest x-ray, 2 views services. These records cover Medicare fee-for-service activity, including eligible younger beneficiaries; they do not measure total practice volume or clinical quality.

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