Based on Medicare claims data, Dr. Chamis performed 474 echocardiogram, transthoracic services. These records cover Medicare fee-for-service activity, including eligible younger beneficiaries; they do not measure total practice volume or clinical quality.

Note that these figures represent what Medicare pays, not your out-of-pocket cost, which depends on your specific insurance plan and deductible.

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