Why Medicaid Claims Are Harder to Collect: What It Costs Hospitals

Ask any hospital billing director to name their most labor-intensive payer, and Medicaid will likely come up before the conversation is over. The reason has less to do with the patients than with the mechanics: getting a Medicaid claim paid is simply harder, and the data backs that up.

In a national survey of hospitals and health systems, Premier Inc. found that Medicaid managed care plans initially denied 16.7% of claims, the highest rate of any payer category surveyed, compared with 8.4% for traditional Medicare. Kodiak Solutions' 2026 benchmarking analysis of more than 2,300 hospitals reached a similar conclusion: Medicaid led both initial and final denial rates across payer categories in 2025, contributing to a 25% jump in industry-wide net revenue leakage to more than $48 billion.

Why Medicaid Claims Are More Difficult to Collect

A few structural factors explain the gap.

First, timely filing windows for Medicaid are established by each state and are often shortened further by individual managed care contracts, ranging anywhere from 90 days to a full year depending on the state and health plan. A hospital operating across several states—or contracting with multiple Medicaid MCOs within one state—is effectively managing different filing deadlines for nearly every claim category. Miss one, and the claim is often denied without appeal rights.

Second, eligibility is far less stable than with commercial insurance. Patients move between Medicaid eligibility categories, lose and regain coverage during redetermination cycles, or qualify retroactively after a hospital stay has already been billed to self-pay. Each of these scenarios can trigger a denial that has nothing to do with the clinical appropriateness of the care delivered.

Third, five for-profit companies—Centene, Elevance, UnitedHealth, Molina, and CVS Health—now administer close to half of all Medicaid managed care enrollment nationally, according to KFF. Each operates its own prior authorization requirements, documentation standards, and appeals process, layered on top of the state's underlying Medicaid rules.

A denial reason code that means one thing for a state Medicaid fee-for-service program can mean something entirely different at an MCO across town.

The Financial Impact on Hospitals

The cost of these administrative challenges extends well beyond the denied claim itself.

Hospitals across all payer categories spent an estimated $19.7 billion in a single year managing denied claims, according to the American Hospital Association, and that figure has almost certainly increased as denial volumes continue to rise.

Every hour a biller spends chasing a Medicaid timely filing exception, correcting eligibility issues, or resubmitting documentation is an hour that cannot be spent on higher-value revenue recovery activities. The result is increased labor costs, delayed cash flow, and greater administrative burden for already stretched revenue cycle teams.

Medicaid Requires Its Own Revenue Cycle Workflow

For revenue cycle leaders, the lesson is straightforward: Medicaid requires its own workflow rather than a modified version of the commercial insurance process.

Hospitals that build Medicaid-specific tracking for filing deadlines, MCO-specific documentation requirements, eligibility monitoring, and denial trends are generally better positioned to improve reimbursement and reduce avoidable write-offs.
