Imposes requirements and restrictions on insurer and coordinated care organization audits of claims for reimbursement submitted by behavioral health treatment providers.
HB 4028 is a behavioral health insurance and Medicaid audit reform bill. It creates new rules for how insurers, coordinated care organizations (CCOs), and the Oregon Health Authority may audit claims submitted by behavioral health treatment providers, including mental health and substance use disorder providers. The bill requires these entities to give providers plain-language descriptions of claim requirements, examples of documentation standards, and notice of changes to those requirements before they take effect.
The bill also limits when audits may occur and how they must be conducted. For insurers, audits of paid claims generally may not reach back more than 12 months, except in suspected fraud cases; for CCOs and OHA, the lookback period is generally three years unless there is fraud or improper payment. Audits must be completed within set timeframes, reviewed by a behavioral health professional, and may not overturn prior medical-necessity determinations or prior authorizations in most cases. The bill further restricts recoupment practices, bars recoupment for clerical errors, limits sampling-based audits, prohibits incentive-based auditor compensation, and requires repayment plans and dispute protections for providers and patients.
HB 4028 also amends Oregon’s behavioral health parity law, ORS 743B.427, by expanding annual reporting requirements for carriers that offer behavioral health benefits. Carriers must submit detailed information to the Department of Consumer and Business Services about nonquantitative treatment limitations, comparative analyses between behavioral health and medical/surgical benefits, denial and appeal data, reimbursement rates, medical management practices, and other parity-related information. The department must then provide a yearly summary to legislative committees.
The bill’s impact on state law is to tighten oversight of insurer and public-program audit practices while increasing transparency around behavioral health parity compliance. It adds new statutory obligations for insurers, CCOs, OHA, and carriers, and it creates enforceable limits on recoupment, audit timing, audit staffing, and patient financial liability. The operative date for the audit provisions is January 1, 2027, with the reporting changes taking effect after session adjournment.
Overall sentiment appears strongly supportive. The bill advanced out of House committee unanimously and later passed House third reading by a wide margin, indicating broad agreement that behavioral health providers need clearer rules and stronger protections from aggressive audit and recoupment practices. The main points of contention, to the extent reflected in the text, are the balance between preventing improper payments and avoiding burdensome audits, and the extent to which insurers and public payers can continue to use medical management tools without violating parity requirements.
HB 4028 amends Oregon insurance and Medicaid-related law by adding new audit standards for behavioral health claims and by expanding behavioral health parity reporting under ORS 743B.427. It affects insurers, third-party auditors, CCOs, OHA, behavioral health providers, and carriers offering individual or group health plans with behavioral health benefits. The bill restricts audit lookback periods, audit timing, recoupment authority, auditor compensation structures, and patient billing during disputes, while also requiring more detailed annual parity disclosures to DCBS and legislative committees.
The available voting history suggests the bill was received favorably and with little opposition. It passed the House committee 8-0 and later passed House third reading 39-1, indicating broad bipartisan support for the measure’s provider protections and transparency requirements. No committee transcript concerns are provided, but the legislative pattern suggests the bill was viewed as a targeted reform rather than a controversial overhaul.
The principal policy tension in HB 4028 is between provider protections and payer oversight. Supporters appear to favor clearer notice, shorter audit windows, behavioral-health-specific review, and limits on recoupment to reduce administrative burden and patient disruption. Potentially affected parties who may have concerns are insurers, CCOs, and the Oregon Health Authority, because the bill constrains audit discretion, limits financial incentives tied to recoupment, and requires more detailed reporting and dispute procedures. The bill also draws a line around fraud and improper payment, preserving broader audit authority in those cases, which reflects an attempt to balance enforcement with fairness.
