Summary
Dr. Karha is a clinical cardiology specialist, with moderate Medicare volume, with consulting-driven industry engagement in the top 4% of TX peers, with 19 years of NPI registration.
This summary is auto-generated from federal data. It describes data availability and patterns — not clinical quality. Read our methodology →
Frequently Asked Questions
Is Dr. Karha experienced with hospital follow-up visit, high complexity?
Based on Medicare claims data, Dr. Karha performed 114 hospital follow-up visit, high complexity services. Research suggests that higher procedure volume is often associated with better outcomes, particularly for complex procedures. Note that Medicare data only captures patients aged 65 and older, so the total practice volume across all patients is likely higher.
Does Dr. Karha receive payments from pharmaceutical companies?
Yes. Dr. Karha received a total of $144,517 from 22 companies across 403 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. Patients may wish to ask their doctor about these relationships, especially if a recommended drug or device appears in the payment records.
How do Dr. Karha's costs compare to other cardiologists in Austin?
Dr. Karha's average Medicare payment per service is $72. 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. Karha) 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 →
