The 2025-26 Budget:
Medi-Cal Pharmacy Spending
GABRIEL PETEK | LEGISLATIVE ANALYST | APRIL 2025
SUMMARY
Medi-Cal Pharmacy Spending Has Grown Over Time. Medi-Cal, California’s Medicaid program, covers
the cost of prescription drugs (among other health care services) for low-income people. From 2018-19
through 2023-24, we estimate Medi-Cal pharmacy spending nearly doubled. Nearly half of this growth
was associated with certain drugs treating diabetes, obesity, and inflammatory diseases. Accordingly,
the Governor’s budget assumes continued growth in pharmacy spending through 2025-26, including a
substantial upward revision in estimated spending in 2024-25.
Medi-Cal Pharmacy Data Could Be More Transparent. On a total funds basis (both state and
federal funds), the assumed overall growth in pharmacy spending under the Governor’s budget appears
to be roughly in line with recent data highlighting growth in utilization and cost. However, given data
constraints, assessing some of the administration’s underlying cost assumptions is difficult. For example,
the administration assumes growth in drug utilization among undocumented beneficiaries. While this growth
is plausible, historical data on pharmacy use for this population is limited. Also, limited data on drug price
discounts and rebates makes assessing the transition to Medi-Cal Rx in 2022 difficult. In light of these
limitations, we recommend the Legislature (1) direct the Department of Health Care Services (DHCS) to
report specified data annually and (2) withhold action around Medi-Cal pharmacy spending in 2025-26 until
May Revision, when updated data are available.
State Could Better Prepare for Drug Spending Volatility. Though the full effects of Medi-Cal Rx
are uncertain, it is likely the new system has increased budget volatility and uncertainty in the Medi-Cal
program. This is because the state now pays for all drug costs directly under Medi-Cal Rx, which are
highly variable year to year. (Prior to the creation of Medi-Cal Rx in 2022, the state indirectly paid for most
prescription drugs, like most Medi-Cal benefits, through contracts with health plans that cover the cost
of care for beneficiaries.) As a result, significant midyear revisions—much like the one in the current-year
budget—may be more common moving forward. To help manage this volatility, the state in 2019-20 created
a new fund account to reserve a portion of drug rebate funds. To date, however, reserve amounts have been
inconsistent. To better prepare for budget volatility moving forward, we recommend the Legislature tighten
the mission and rules around this fund account in state law.
State Has Limited Control Over Pharmacy Spending. Given the state’s constrained fiscal situation, the
Legislature may face pressure to limit General Fund spending growth, including in the Medi-Cal program.
The state has limited ways of doing so with regard to Medi-Cal pharmacy spending specifically. For example,
the Legislature could adjust coverage of optional drugs (such as anti-obesity drugs) or impose certain
utilization controls (such as requiring copays). That said, there are limitations and trade-offs to consider.
Most notably, federal rules limit how states can control pharmacy spending, and the federal government
is contemplating whether to impose additional constraints. Also, caution is warranted when reacting to
emerging trends, given the historical volatility of the drug market. To this end, we recommend the Legislature
continue to monitor spending trends, particularly around optional drugs. To the extent the Legislature takes
actions this year to limit spending, it will want to ensure such actions have measurable and likely impacts on
long-term state costs.

work in the Medi-Cal program.
How Do Drug Rebates Work in Medi-Cal?
Federal Rebates Are Mandatory and Determined by Formula. Created in 1990 and revised
over time, the federal Medicaid Drug Rebate Program determines federal rebates for drugs in
the Medicaid program. Drug makers must agree to participate in this program as a condition
of having their drugs covered by state Medicaid programs. Rebates for specific drugs, which
are considered confidential, are set by formulas. Under these formulas, a drug’s initial rebate is
between 13 percent and 23 percent of its price, depending on the type of drug. Over time, the
initial rebate increases if the drug’s price rises faster than inflation. Consequently, older drugs
(which have tended to have price increases over time in excess of inflation) can come with much
higher rebates. Drug makers pay their rebates to states, which then submit the federal share of
savings to the federal government.
State-Negotiated Supplemental Rebates Are Voluntary. In addition to the mandatory
federal rebates, the state (through the Department of Health Care Services) negotiates additional
rebates with manufacturers. Unlike for federal rebates, drug makers are not required to provide
state-negotiated supplemental rebates. To induce participation, California leverages its
negotiating power by including drugs with supplemental rebates in its preferred drug list. State
supplemental rebates historically have comprised just a fraction of the overall savings from
Medi-Cal rebates.

KEY TRENDS
In this section, we summarize key historical and Below, we summarize trends on overall pharmacy
projected trends in Medi-Cal pharmacy spending. spending and spending by type of drug.
As the nearby box explains, we analyzed trends
Overall Spending
by combining data from federal and state sources.
Because we combined data from different sources, Pharmacy Spending Has Grown in Recent Years,
some of which use different methodologies, our in Line With Medi-Cal Program. Over the years,
findings have some limitations. As such, the below Medi-Cal pharmacy spending has continued to grow,
trends should be treated as rough estimates. both on a gross basis and after netting out rebates.
How Did We Compile Estimates in This Brief?
For Overall Spending, Two Key Sources. To measure overall Medi-Cal pharmacy spending
trends over the last few years, we used two key sources of data. (Our methodology largely follows
the approach taken by other health policy organizations, such as the Kaiser Family Foundation.)
• Gross Spending—State Drug Utilization Data. Under federal law, states must report to
the federal government quarterly drug utilization information in their Medicaid programs.
These data include the number of prescriptions and gross Medicaid spending for each drug.
The data are publicly available. Accordingly, we downloaded California’s drug utilization
data from the first quarter of 2018 through the second quarter of 2024 (the latest quarter
available at the time of our analysis).
• Rebates—Federal Financial Management Reports. Federal law also requires states to
submit annual financial information on their Medicaid programs. These financial reports,
which also are available to the public, include line-item information on federal and state
supplemental drug rebate savings. Accordingly, we downloaded available financial reports
through federal fiscal year 2023 (the last year available at the time).
For Drug-Level Spending, Federal Drug Classifications. We also used drug utilization
data to track which drugs have driven changes in pharmacy spending. However, the data on
their own are not conducive to effective trend analysis. This is because each quarter of data
contains around 40,000 line items, and some drugs are spread across multiple lines. To better
simplify these data, we used each drug’s classification as identified under the Food and Drug
Administration’s National Drug Code Directory. These classifications generally categorize
drugs based on how they work, how they are used, and other factors. There are over 1,000 such
classifications in the federal directory.
Analysis Likely Omits Some Key Kinds of Drug Claims. Generally, states are required
to report Medicaid drug utilization data connected to federal drug rebates. Federal guidance
directs states to exclude reporting certain drug claims outside of the rebate system. For example,
states are to exclude drugs that come with federal price discounts (known as 340B discounts).
These drugs do not come with rebates, because federally required price reductions already
occurred at the front end when the pharmacy purchased the drugs. Federal guidance also directs
states to exclude claims that do not come with a federal share of cost. For example, drugs for
undocumented immigrants do not qualify for federal cost sharing or rebates. As such, these kinds
of drugs likely are excluded from our trend analyses.
