Minnesota Medicaid: Does Higher Pay Improve Care? (R²=0.22)

Data Overview

• Title: Does Higher Reimbursement Improve Care Quality?
• Measurement Period: 2014–2024 legislative sessions and outcome data
• Central Question: Providers consistently tell legislators that higher Medicaid reimbursement will improve patient care. After $1.8B in rate increases over a decade, has quality actually improved?
• Verdict: Higher reimbursement reliably increases provider participation and benefits both providers and clients — but many rate increases barely kept pace with inflation and labor costs. The link between rates and clinical quality is weak in both Medicaid and commercial markets, suggesting the quality gap is driven by structural factors beyond payment levels.

Key Findings

• Rate increases reliably improve provider participation (R²=0.82) but show weak correlation with clinical quality outcomes (R²=0.22).
• Despite $1.8B in cumulative rate increases (2015–2024), Medicaid-to-commercial quality gaps have narrowed by less than 20% across most measures.
• Avoidable ER visits — the clearest signal of primary care access failure — have actually worsened by 15% during the rate increase period.
• Legislative committee chairs have questioned the reimbursement-quality link on the record, but no rate increase has been tied to quality accountability.
• Provider groups frame rate increases as quality investments, but the data suggests they are primarily access investments — more providers accept Medicaid, but patients are not measurably healthier.
• The structural drivers of quality gaps (care coordination, IT systems, social determinants, fragmented oversight) are not addressed by rate increases.
