Medi-Cal reimburses healthcare providers through two main channels: fee-for-service, where the state pays providers directly for each visit or procedure, and managed care, where the state pays a monthly fee per enrollee to a health plan that then pays providers. Most Medi-Cal beneficiaries are enrolled in managed care plans, so the majority of reimbursement flows through that second path.
Fee-for-Service vs. Managed Care
In the fee-for-service (FFS) model, a provider delivers a covered service and bills the state directly. The state reviews the claim and pays a set amount based on its fee schedule for that specific procedure or visit. This model is straightforward but applies to a shrinking share of the Medi-Cal population, mostly covering services that managed care plans don’t handle, such as certain long-term care or dental services.
Under managed care, the state pays a health plan a fixed monthly amount, called a capitation rate, for each person enrolled in that plan. The plan then takes on the financial responsibility for covering all the Medicaid services that enrollee might need. The plan pays its network providers either through negotiated rates, subcapitation arrangements (where a provider group accepts a fixed payment and assumes some financial risk), or other contracts. Some plans delegate nearly all the risk for a beneficiary to another organization through what’s called a global subcapitation arrangement.
California operates several managed care models across counties: County Organized Health Systems, Geographic Managed Care, Two-Plan, Single-Plan, and Regional models. Which model you encounter depends on where you practice or receive care.
How Capitation Rates Are Set
The California Department of Health Care Services (DHCS) develops capitation rates annually following federal guidelines from CMS. Counties are grouped into rating regions, and each managed care plan receives a rate specific to its region and the population it serves.
The process starts with real data. DHCS collects membership numbers, medical utilization, and cost data from each plan for a recent fiscal year. For the 2025 rates, plans submitted data from state fiscal year 2022-23. DHCS then adjusts that base data to account for changes in the covered population’s health risk, updates to the benefit package, program changes that weren’t fully reflected in the historical data, and projected cost trends going forward. Administrative costs and an underwriting gain margin are layered on top. The result is an actuarially sound rate range, and DHCS certifies a final rate within that range for each plan.
Risk adjustment is a key piece: plans covering sicker or more complex populations receive higher per-member payments than plans with healthier enrollees, so the capitation rate reflects the actual cost of care, not just a flat average.
How Medi-Cal Rates Compare to Medicare
Medi-Cal has historically paid providers significantly less than Medicare, which itself pays less than most private insurance. This gap has been a major reason some providers limit or decline Medi-Cal patients. California addressed this in recent budget cycles by raising targeted Medi-Cal rates to no less than 87.5% of the corresponding Medicare rate. That increase folded in previous supplemental payments and eliminated earlier across-the-board payment reductions that had been in place since 2011 under AB 97.
Even at 87.5% of Medicare, Medi-Cal reimbursement remains lower than what most commercial insurers pay. But the rate increase narrowed the gap enough to meaningfully improve provider participation for the affected services.
Payment Timelines
DHCS expects managed care plans to pay clean claims (claims with no errors or missing information) within 30 calendar days of receiving them. If a plan fails to pay a clean claim within 45 working days, it owes the provider interest at 15% per year, starting from the first day after that 45-working-day window. Plans that contest or deny a claim must give the provider specific reasons within statutory timeframes.
For fee-for-service claims submitted directly to the state, timelines are governed by similar prompt-payment rules. In practice, payment speed depends heavily on whether the claim is submitted electronically (faster) and whether it’s free of errors.
Common Reasons Claims Get Denied
Claim denials are one of the biggest frustrations in Medi-Cal reimbursement. The most frequent denial reasons fall into a few categories:
- Eligibility issues: The patient wasn’t eligible for Medi-Cal benefits on the date of service.
- Managed care conflicts: The service is covered under the patient’s managed care plan, so it can’t be billed to Medi-Cal’s fee-for-service system.
- Duplicate claims: The service was already paid on a previous claim.
- Frequency limits exceeded: The patient has already received the maximum number of that service allowed within a set time period.
- Invalid diagnosis codes: The diagnosis code submitted doesn’t match the date of service or the procedure performed.
- Missing Medicare information: For patients who have both Medicare and Medi-Cal, proof of Medicare’s payment or denial is required before Medi-Cal will process the claim.
- Authorization problems: A required prior authorization was incomplete or missing.
Most denials stem from administrative errors rather than clinical disagreements. Verifying a patient’s eligibility and plan enrollment before delivering services prevents the two most common denial codes.
How Providers Enroll for Reimbursement
Before receiving any Medi-Cal reimbursement, providers must enroll through DHCS’s Provider Enrollment Division. The enrollment criteria are defined in Title 22 of the California Code of Regulations. California uses a web-based portal called PAVE where providers can submit new enrollment applications, report changes to existing enrollments, and respond to revalidation requests. There is an application fee, and DHCS periodically requires enrolled providers to revalidate their enrollment to maintain active status.
Enrollment as a Medi-Cal provider is separate from contracting with a managed care plan. To see managed care patients, you typically need both: active Medi-Cal enrollment with the state and a network contract with the specific health plan covering your patients. Without both, claims will be denied regardless of whether the service was medically appropriate.
