Q & A

What do you love most about your job?

“I love getting into the data – identifying potential issues and helping develop ways to solve problems.”


How did you get into 340B?

I got into 340B while working at the Office of Inspector General (OIG) in Chicago.  340B was my first study (and first study working with Madeline) and I never really left drug pricing.


What do you love most about working with your business partner?

I love that Madeline and I are able to approach issues differently but still communicate well.  We are very Yin and Yang – and together offer a very broad, comprehensive approach.  I also think that it is pretty amazing that even though we are so different, we are still able to communicate.  And of course, I like Madeline as a person.


When you aren’t working, we can find you _____________.                                        When I am not working, I am generally spending time with the family.  The four kids keep us pretty busy!

What do you love most about your job?

As someone that has lived through so much of the 340B program history, I absolutely love sharing my point of view on the history, current state and potential future state of 340B.  I love helping clients understand the regulatory environment and helping them prepare for changes or draft comments to lawmakers. I could talk about the program for hours… but I am not sure who would keep listening!

How did you get into 340B?

My first project at the OIG was examining ADAP participation in 340B. Instead of moving on to a different program in HHS, my boss thankfully recognized the learning curve associated with 340B and let me develop my specialty.  I don’t think anyone would have predicted I would have spent my career thus far in the same space, but I just love it.

What do you love most about working with your business partner?

I often joke that Suzanne is my work soul mate, but it is true! We started working together at the OIG and have an effortless way of communicating and dividing work.  I think we can communicate telepathically at this point! Suzanne pushes me to think about things with fresh eyes and her data mining skills are the best in the industry.

When you aren’t working, we can find you _____________. 

Enjoying time with my husband and three kids, especially outside on bikes and hikes, and traveling. I love yoga/pilates, the science of nutrition, and reading. I think everyone knows if I weren’t doing this, I would have been a stylist!

Our Services

At Rx|X Consulting, we’re committed to informing, coaching, and cultivating your team’s ability to effectively maneuver through the world of 340B compliance. We foster a comfortable learning environment to push beyond what’s required for a routine HRSA audit.


Rx|X prides itself on the high quality of its deliverables and the tools we provide our clients for success going forward. Our engagements may be customized to assist with even the most complex aspects of 340B compliance, to navigate new healthcare legislation, and to offer continued training and education to ensure you have peace of mind as your business adapts and grows.

Contract Pharmacy Audits

According to HRSA’s Office of Pharmacy Affairs, “All covered entities are required to maintain auditable records and are expected to conduct annual audits of contract pharmacies that are performed by an independent outside auditor as a way to fulfill their ongoing obligation of compliance.” Rx|X’s audit includes all of the expected elements, including transaction testing, contract review, P&P review, OPAIS database review, and comparison of purchases to dispenses.

HRSA Audit Preparation & Support

While our education and external audits focus on getting you prepared for a HRSA audit, Rx|X is fully supportive and responsive from the time you receive a HRSA notice through the final audit report and potential Corrective Action Plan.


Through the course of our audits, we provide feedback on your ability to respond seamlessly to HRSA’s Data Request List and get you organized. If you are selected for an audit, we can support you on-site or remotely and will review any/all of the data prior to submission. Rx|X has successfully helped entities overturn audit findings and will be your advocates through the whole process!

Program Strategy

When you partner with Rx|X, you benefit from the wealth of experience that 20+ years in the industry brings. We see what works (and what doesn’t) for program setup, staffing, billing, and interpretations and share best practices with our clients. At this point, we are able to quickly provide feedback and/or financial data on things like the value of new contract pharmacies, ownership changes, developing retail networks, setup on services, and many others. We also pair similarly-situated clients to share lessons and options for problem solving and often work with legal or outside counsel on these matters.

Comprehensive Audits

HRSA encourages entities to examine their in-house operations and policies and procedures through external auditors as well. The scope of an Rx|X comprehensive audit includes a review of an entity’s total 340B operations including, but not limited to: mixed use, in-clinic, retail pharmacy, and contract pharmacy. This is your opportunity to invest in a complete look at all of the keystone pillars of compliance.  All information is presented to the team as part of our Rx|X Workbook—our organized deliverable of audit work papers and recommended action steps.


Whether you are new to 340B, restructuring, switching split-billing or TPA vendors, or looking to increase efficiency, Rx|X can help guide analysis and project management.

Dispute Resolution

Rx|X can help review the facts and circumstances of any matter between an entity and HRSA or a manufacturer to work toward a fair and equitable resolution.


We customarily support legal departments or outside counsel on disputes or audit results.

Education & Training

340B is complicated and changes frequently. Rx|X can translate your regulatory requirements to various members of the team, be it IT, Finance, Compliance, or Operations through focused education and training.


With Rx|X’s proper guidance, coordination, documentation, and advice on the best strategies, your 340B program will thrive. All clients have access to our members-only site, Next Level where we share all the latest insider news, tips, host webinars, and provide a space for our clients to network.


HRSA’s audits are intended to test whether an entity can properly oversee its 340B operations.


Rx|X reviews the completeness of your self-auditing plan and advises you on how to spend your time wisely. We also ask how issues are identified, reported and resolved. At Rx|X, we help you optimize your testing standards and teach you about the value of working smarter with your data.

340B Data Analytics

Transaction testing is a critical component of program monitoring, but what else can you learn about your setup and processes by analyzing your 340B data in novel ways?


Reviewing your purchasing and dispensing reveals an incredible amount of feedback for continuous program improvement and practical recommendations for optimization. Rx|X’s deliverable exposes potential issues with compliance and opportunities for efficiency at the same time.
