Frequently Asked Questions

Is Dr. Martinez Parra experienced with anesthesia for endoscopic procedure on esophagus, stomach, or upper small bowel?
Based on Medicare claims data, Dr. Martinez Parra performed 58 anesthesia for endoscopic procedure on esophagus, stomach, or upper small bowel services. Research suggests that higher procedure volume is often associated with better outcomes, particularly for complex procedures.

Does Dr. Martinez Parra receive payments from pharmaceutical companies?
Yes. Dr. Martinez Parra received a total of $246 from 2 companies across 6 individual payments. These payments are legal, publicly disclosed under the federal Sunshine Act, and common among physicians — 57% of all U.S. physicians receive at least one industry payment.

How do Dr. Martinez Parra's costs compare to other surgerists in Chicago?

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 Very High for Dr. Martinez Parra) 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 a long track record of practice, Medicare participation, and industry disclosure. 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. Read our full methodology →
Is this data up to date?
Each data source has its own update cycle. Provider registry data (NPPES) is updated weekly. Medicare enrollment (PECOS) is updated monthly. Medicare practice data has a ~2 year lag — the most recent available is typically 2 years prior. Industry payment data (Open Payments) is published annually, usually in June, covering the prior calendar year. We display the data date prominently on each section so you always know how current it is. See our data freshness policy →
