A federal audit uncovered systemic fraud in Colorado’s Medicaid autism therapy program, revealing at least $77.8 million in improper payments with potential total exposure exceeding $150 million. Every single claim reviewed violated federal standards, exposing massive oversight failures in taxpayer-funded healthcare.

Audit Reveals Total System Failure

The Office of Inspector General examined Colorado’s Applied Behavior Analysis therapy program, which treats children with autism spectrum disorder through Medicaid funding. Investigators reviewed 100 enrollee-months of claims from 2022 and 2023. The result shocked auditors: 100 percent of sampled claims included improper or likely improper payments. The finding signals structural collapse rather than isolated billing errors, indicating systemic problems in how Colorado administers taxpayer dollars for vulnerable children’s healthcare.

Colorado’s spending on autism therapy exploded from $60.1 million in 2019 to $163.5 million by 2023. That rapid growth occurred without adequate safeguards. The audit found providers billed for services lacking proper documentation, clinical justification, or eligibility verification. Federal investigators are demanding Colorado refund $42.6 million immediately. Another $112.5 million in questionable payments requires additional review, potentially pushing the total fraud to $155 million.

Weak Controls Enabled Massive Waste

The problem stems from administrative failures, not a single policy mistake. Colorado failed to establish clear documentation standards, provided unclear billing guidance to providers, maintained inconsistent credentialing requirements, and conducted insufficient post-payment reviews. Providers operated without proper instructions on billable therapy time, required documentation, or treatment session recording procedures. This lack of oversight created conditions where improper billing became standard practice across the entire program.

What Happens Next

The Inspector General issued five recommendations requiring Colorado to return improper funds, strengthen documentation requirements, conduct regular audits, review authorization procedures, and reexamine tens of millions in suspect claims. The Colorado Department of Health Care Policy and Financing agreed with most recommendations. This scandal adds to growing concerns about fraud in government healthcare programs, particularly as spending increases without matching accountability. Families relying on legitimate autism therapy services may face program changes as the state implements corrective measures to prevent future fraud.
