Should you be concerned? Payments from pharmaceutical and device companies are legal and common — 57% of U.S. physicians receive at least one. They often reflect legitimate consulting, research, or education. What matters is whether a recommended drug or device appears in your doctor's payment records. If so, consider asking your doctor about it. How to interpret this data →

The majority of payments (95%) are for speaking programs and promotional activities, which reflect participation in industry-sponsored educational or marketing events.

Summary

Dr. Kreitenberg is a mixed practice specialist, with above-average Medicare volume (top 8% in CA), with speaking/promotional industry engagement in the top 1% of CA peers.

This summary is auto-generated from federal data, describing data availability and patterns. Read our methodology →

Frequently Asked Questions

Is Dr. Kreitenberg experienced with tocilizumab injection (actemra)?
Based on Medicare claims data, Dr. Kreitenberg performed 27,364 tocilizumab injection (actemra) 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. Kreitenberg receive payments from pharmaceutical companies?
Yes. Dr. Kreitenberg received a total of $674,486 from 54 companies across 2,439 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. Kreitenberg's costs compare to other rheumatologists in Tarzana?
Dr. Kreitenberg's average Medicare payment per service is $18. 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. Kreitenberg) 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 →
