Based on Medicare claims data, Dr. Shivshanker performed 439 tissue pathology examination, moderate complexity services. These records cover Medicare fee-for-service activity, including eligible younger beneficiaries; they do not measure total practice volume or clinical quality.
Does Dr. Shivshanker receive payments from pharmaceutical companies?
Yes. Dr. Shivshanker received a total of $17,771 from 56 companies across 847 payment records. A record can group multiple payments. These transfers are publicly disclosed through CMS Open Payments.

How do Dr. Shivshanker's costs compare to other gastroenterologists in Houston?
Dr. Shivshanker's average Medicare payment per service is $66. 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. Shivshanker) 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.

Source publication dates and the snapshots loaded on this site can differ. Rebuilding a page does not refresh its source records. Check the Medicare reporting year and the payment interval shown above; consult the linked official sources for newer releases and current registry details. See our data freshness policy →
