HB26-1412 authorizes the Colorado Department of Health Care Policy and Financing (HCPF) to use statistical sampling and extrapolation to identify and recover Medicaid overpayments in two service areas: nonemergency medical transportation and pediatric behavioral therapy, including applied behavioral analysis. The bill applies to audits initiated after July 1, 2026, for services delivered from January 1, 2022, through December 31, 2023, and allows the same methods to be extended to 2024-2025 services if an audit finds a statistically significant pattern of overpayments. A statistically significant pattern is defined as a claims error rate exceeding 10 percent.
The bill also requires HCPF to provide providers with a notice of alleged overpayment within 60 days, including the basis, rationale, methodology, and supporting documentation used to calculate the recovery. Providers retain the right to informal reconsideration or formal appeal before recovery begins. If HCPF hires outside auditors for these reviews, the contract may not be contingency-based or tied to a percentage of recovered funds. After each audit, the State Auditor or designee must review whether HCPF used proper statistical methods and report findings annually to the Legislative Audit Committee and Joint Budget Committee.
In addition to the audit and recovery provisions, the bill makes a budget adjustment for the 2026-27 fiscal year by reducing a General Fund appropriation and increasing a cash funds appropriation from recoveries and recoupments. The bill is structured to take effect upon passage, with the appropriation section contingent on enactment of the 2026-27 long bill.
The overall sentiment reflected in the bill text is strongly supportive of stronger Medicaid program integrity and more efficient recovery of improper payments. The legislative declaration emphasizes fraud, waste, abuse, administrative burden, and federal compliance, suggesting the bill is intended to protect state and federal Medicaid dollars. No committee transcript or vote record is provided, but the bill’s final status as signed by the Governor indicates it ultimately received approval.
The main point of contention embedded in the bill is the use of statistical sampling and extrapolation to recover overpayments rather than auditing every claim individually. The bill anticipates concerns about fairness and accuracy by requiring statistically valid methods, notice with detailed methodology, provider appeal rights, and independent review by the State Auditor. Providers in the affected Medicaid sectors are the primary parties impacted, while HCPF, the State Auditor, and state budget committees gain new oversight and recovery responsibilities.
The bill amends Colorado Medicaid recovery procedures in section 25.5-4-301 to expressly authorize HCPF to use statistical sampling and extrapolation for certain provider audits, specifically for nonemergency medical transportation and pediatric behavioral therapy services. It creates a new audit framework for claims from 2022-2023, allows extension to 2024-2025 if a significant error pattern is found, requires detailed notice and appeal rights, prohibits contingency-fee audit contracts, and adds State Auditor review and reporting requirements. It also adjusts state appropriations by shifting funding from General Fund support to recoveries and recoupments in the 2026-27 budget.
The bill appears to have been viewed favorably as a Medicaid integrity and cost-recovery measure. Its findings frame the issue as one of improper billing, documentation problems, and administrative inefficiency, and the bill’s final enactment suggests sufficient support to become law. The absence of recorded opposition in the provided materials limits direct insight into debate, but the structure of the bill shows an effort to balance recovery authority with procedural protections for providers.
The central controversy is whether HCPF should be allowed to estimate overpayments through statistical sampling and extrapolation instead of reviewing every claim individually. Providers in the affected sectors may be concerned about the accuracy and fairness of extrapolated recoveries, especially for older service periods, while the state argues that individual claim-by-claim audits are impractical and under-recover improper payments. The bill addresses these concerns by requiring statistically valid methods, a 10 percent error-rate threshold for extending audits, detailed notice, appeal rights, and independent State Auditor review.
