Globally, pharmacists have long been positioned as central care providers. However, in the U.S., their role in direct patient care has been historically restricted within physician-led models. Reaffirming and expanding pharmacists’ contributions aligns with evidence-based practices and strengthens their impact on population health initiatives.
As pharmacist-driven programs gain traction, Medicaid pharmacists play a pivotal role in closing health gaps and ensuring that policy-driven interventions translate into productive patient outcomes.
This blog post explores how Medicaid pharmacists implement innovative strategies and leverage actionable insights to improve medication adherence, drive cost savings, and enhance population health outcomes.

While pharmacists serve as central care providers worldwide, physician-led models in the U.S. have gradually limited their direct patient care role. Reaffirming their expertise supports evidence-based practices and expands their impact in population health.
Breaking Barriers: Challenges in Medicaid Adherence
Medicaid populations face significant barriers to improving medication adherence, requiring patient-centered and innovative solutions. Key challenges, visually represented below, include:

Medicaid pharmacists are at the forefront of tackling these issues, helping managed care organizations (MCOs) bridge care gaps and reduce disparities that negatively impact adherence rates.¹
Dr. La Kesha Y. Farmer, our founder, has direct expertise in this space, having successfully led multiple Medicaid Clinical Pharmacy Adherence Programs as a Population Health Pharmacist (PHP) within an MCO.
Her leadership advanced medication adherence and generated measurable cost-savings, reinforcing the value of pharmacists in optimizing Medicaid outcomes.
Additionally, studies like Montgomery et al. further validate the impact of Medicaid pharmacists in driving adherence improvements within MCOs.⁴
Medicaid Pharmacists: Improving Medication Adherence Through HEDIS, Advocacy, and Beyond
Medicaid pharmacists go beyond traditional medication therapy management (MTM), leveraging policy-driven interventions and Medicaid-specific adherence strategies to drive measurable improvements in medication adherence. Their work focuses on:
HEDIS Measures: Leveraging Data for Optimal Outcomes
Enhancing Patient Access and Experience
Empowering Patients Through Tailored Education
Leveraging Technology to Improve Adherence
Optimizing MTM for Medicaid Populations
Addressing Social Determinants of Health (SDOH)
Each section below will explore how Medicaid pharmacists drive measurable impact in these areas to improve medication adherence and patient outcomes.
HEDIS Measures: Leveraging Data for Optimal Outcomes
As part of population health pharmacy initiatives, Medicaid pharmacists play a critical role in improving medication adherence by leveraging claims data and metrics to identify and assist non-adherent members and drive measurable outcomes.
An example of metrics include the Healthcare Effectiveness Data and Information Set (HEDIS), a set of quality measures established by the National Committee of Quality Assurance (NCQA)
Real-world programs like the Targeted Intervention Program™ (TIPs) showcase how HEDIS-driven pharmacist interventions enhance clinical performance.⁷
These programs support Medicaid beneficiaries in meeting national health objectives while also providing valuable prescribing insights, such as drug utilization reviews (DURs), to optimize medication use and improve patient safety.

Enhancing Patient Access and Experience
Medicaid pharmacists enhance patient experience by ensuring beneficiaries receive optimized, cost-effective care¹. This includes identifying barriers, triaging patient-provider concerns, and facilitating connections to preferred providers.
These efforts align with the Agency for Healthcare Research and Quality’s (AHRQ) Consumer Assessment of Healthcare Providers and Systems (CAHPS) program, which prioritizes patient-centered care and experience-driven provider selection—both key factors in Medicaid quality initiatives.
Empowering Patients Through Tailored Education
Medicaid pharmacists deliver personalized education that reinforces how medication adherence directly impacts the management of chronic conditions like diabetes, hypertension, and asthma, helping patients achieve improved health outcomes.
By building trust and using culturally competent communication, they empower patients to take control of their health— defined by the World Health Organization (WHO) “as a state of complete physical, mental, and social well-being, not merely the absence of disease or infirmity.”

Leveraging Technology to Improve Adherence
Medicaid pharmacists integrate digital health tools into patient care, harnessing technology as a vital strategy for improving medication adherence.
These innovations enhance patient engagement, streamline provider communication, and address adherence barriers.
Key examples include:
Adherence Reminder Apps: Help patients stay on track with medication schedules.⁵
Telehealth Services: Facilitate real-time, remote consultations to identify and resolve adherence challenges efficiently.⁵
Mobile health (mHealth) tools: Devices such as smartphones, blood pressure monitors, and wireless scales provide timely reminders and enhance patient-provider communication.⁵
By leveraging these digital solutions, Medicaid pharmacists drive sustained medication adherence, leading to improved health outcomes in Medicaid populations.
Optimizing MTM for Medicaid Populations
Medicaid pharmacists leverage managed care frameworks and formulary management to enhance adherence and resolve prior authorization issues, reducing costs. They streamline adherence through packaging and refill coordination.
Beyond adherence, MTM serves as a bridge to care by addressing patient-specific barriers and integrating pharmacy services into broader healthcare initiatives.
Addressing Social Determinants of Health (SDOH)
Medicaid pharmacists, as integral members of the healthcare team, work collaboratively with a diverse group of stakeholders to effectively address SDOH-related challenges that impact medication adherence, ensuring more equitable healthcare access and improved health outcomes.
6 Key SDOH initiatives driven by Medicaid pharmacists include:
Care Coordination.
MCOs have integrated community health workers (CHWs) into health plans, enabling Medicaid pharmacists within these organizations to train CHWs as pharmacy liaisons, supporting medication adherence, retention, and continuity of pharmaceutical care.
Diet and Transportation Support.
Collaborating with community-based organizations (CBOs) to offer transportation assistance and connect patients with Food Rx programs,¹ such as Produce Prescriptions Programs (PRx), which address food insecurity while promoting dietary habits that support chronic disease management goals.
Holistic Care Programs.
Facilitating whole person care using programs like California’s Advancing and Innovating Medi-Cal (CalAIM) to improve care support and address broader health needs.

Medication Access.
Activating prescription delivery services removes access barriers, ensuring patients receive medications without mobility or transportation challenges.¹
Closed-Loop Referrals.
Utilizing platforms like 211 or FindHelp.org to facilitate closed-loop referrals—ensuring patients are successfully connected to essential social services and that healthcare providers receive confirmation of completed referrals, removing barriers that interfere with medication adherence.
Workforce Training.
Research supports SDOH-focused training for pharmacy interns and technicians to assess social needs and adherence barriers.² Medicaid pharmacists, including Dr. Farmer, have implemented similar strategies in managed care, reinforcing the impact of pharmacist-led SDOH initiatives in population health pharmacy.
Shaping Policy: Medicaid Pharmacists Leading Systemic Change
Medicaid pharmacists function as Medicaid Champions, leading policy initiatives by analyzing adherence trends and presenting actionable recommendations to Medicaid policymakers and program leaders.
Their advocacy addresses systemic barriers—such as formulary restrictions, copay challenges, and access limitations—ensuring access to care remains a priority while improving medication adherence.⁶
By shaping policies that eliminate disparities, their leadership advances equitable care and drives systemic change.
Dr. Farmer exemplified this impact by presenting her clinical pharmacy best practices on improving medication adherence to the Global Medi-Cal DUR Board of the California Department of Health Care Services (DHCS).
She shared how she integrated culturally competent care models into her program development to advance health equity, driving improved health outcomes.
Her expertise in cultural competency is further detailed in 9 Proven Strategies for Reducing Health Disparities in Pharmacy Practice, which highlights actionable approaches to addressing health inequities and fostering systemic change.

Redefining Leadership: Medicaid Pharmacists as Population Health Pharmacy Experts
The impact of Medicaid pharmacists on population health pharmacy is evident in their leadership of initiatives that improve medication adherence. The following strategies illustrate how their efforts enhance patient outcomes and strengthen healthcare systems.
Reducing Healthcare Costs by Improving Medication Adherence
Medicaid Pharmacists help decrease hospitalizations and emergency room visits, generating substantial cost savings for Medicaid programs.¹ ³
Given that the U.S. has the highest per capita GDP for healthcare, Medicaid pharmacists—like their non-Medicaid counterparts—help bridge cost gaps by optimizing medication use and reducing preventable health expenditures.
This finding aligns with the Triple Aim framework—enhancing patient experience, improving population health, and lowering healthcare costs—reinforcing Medicaid pharmacists’ role in delivering sustainable, high-quality care.
Advancing Cultural Competency in Pharmacy Practice
Cultural competency is a cornerstone of population health pharmacy, ensuring that medication adherence strategies account for diverse patient needs, beliefs, and social determinants of health.
Medicaid pharmacists integrate culturally tailored interventions into patient care, recognizing how language barriers, historical mistrust, and systemic inequities influence adherence.
Race concordance—patients being treated by healthcare providers of the same racial/ethnic background—has been shown to increase trust and engagement, reinforcing the need for diverse representation within pharmacy leadership.
By embedding cultural competency into Medicaid pharmacy programs, Medicaid pharmacists strengthen patient relationships, improve adherence, and advance health equity.

Collaborating with Interdisciplinary Teams to Improve Medication Adherence
Medication adherence extends beyond pharmacy—it requires a multidisciplinary, team-based approach for sustainable patient outcomes.
Medicaid pharmacists collaborate across disciplines to align patient-centered medication plans with broader healthcare goals.
Partnering with physicians, nurses, case managers, and social workers, they advocate for medication access and treatment optimization, reducing disparities and enhancing outcomes.
Their leadership in clinical interventions ensures adherence remains a priority across healthcare touchpoints.
Case Study: Medicaid Pharmacists Reducing Costs & Improving Adherence
Medicaid pharmacists transform population health pharmacy principles into reproducible outcomes, reducing costs and improving medication adherence.
The following case study highlights pharmacist-led interventions that successfully improved adherence and strengthened Medicaid program efficiency.
A Medicaid initiative targeting high-risk, non-adherent patients with chronic conditions integrated MTM sessions and community-based partnerships (CBOs), resulting in:
A 15% increase in adherence rates among participants.¹
A 25% reduction in hospital readmissions through improved chronic disease management.¹
Significant cost savings, reinforcing the effectiveness of pharmacist-led interventions.¹
These results underscore the critical role of Medicaid pharmacists in improving medication adherence and advancing sustainable population health pharmacy outcomes.

Medicaid Pharmacists: Leading the Next Era of Medication Adherence
Medicaid pharmacists are more than medication experts—they are Medicaid Champions, leading population health pharmacy efforts.
This article has demonstrated how Medicaid pharmacists advance the profession by closing care gaps and optimizing healthcare frameworks.
Their work aligns with evidence-based practices and underscores the necessity of expanding Medicaid pharmacist-led initiatives to integrate their expertise into policy and practice, particularly within state-based population health models (looking at you, DHCS).
As the healthcare landscape evolves, Medicaid pharmacists must remain central to efforts that advance collective population health pharmacy initiatives.
Sustaining their impact will require continued investment, system-wide support, and collaboration, ensuring that pharmacist-driven solutions remain at the forefront of equitable and sustainable healthcare.
