Is Dr. Mack experienced with eye photography?

Does Dr. Mack receive payments from pharmaceutical companies?
Yes. Dr. Mack received a total of $4,718 from 15 companies across 66 payment records. A record can group multiple payments. These transfers are publicly disclosed through CMS Open Payments. Disclosure alone does not establish their legality or effect on care.

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