Connecticut Mental Health Parity Law 2026: What Changed for Behavioral Health Providers

Practice owner reviewing Connecticut mental health parity law denial letters at a desk

The Connecticut mental health parity law got teeth in 2025, and in April 2026 the state showed how it plans to use them. Parity means a health plan cannot treat mental health and substance use benefits worse than medical and surgical benefits. For providers, it can change how denials, authorizations and reimbursement look over time.

This post uses the six-part payer update format. It is operational guidance on Connecticut mental health parity law, not legal advice. Talk to counsel before you act on any parity theory.

What changed in the Connecticut mental health parity law

Two things happened.

1. A new law. Public Act 25-94 (Substitute Senate Bill 10), according to the legislature’s Office of Legislative Research summary, strengthened parity enforcement:

  • Carriers must certify parity compliance to the insurance commissioner every year, beginning by March 1, 2026.
  • A carrier’s reported compliance is now public. Earlier law kept carrier identities confidential.
  • Civil penalties can reach $100 per covered member, capped at $625,000 a year. The old cap was $15,000.
  • Late or missing filings can draw $100 per day, capped at $625,000.
  • The commissioner can hire outside experts to review nonquantitative treatment limit violations.
  • For prescribers: a step therapy ban for drugs treating schizophrenia, major depressive disorder and bipolar disorder became permanent instead of expiring January 1, 2027.

2. A first enforcement report. On April 22, 2026, the Connecticut Insurance Department highlighted findings from its annual parity compliance report. It found gaps in documentation of coverage decisions, differences in behavioral health network access, and reimbursement approaches that did not meet comparability standards. It said it initiated enforcement actions against Aetna, Anthem, ConnectiCare, Cigna and UnitedHealthcare.

When it takes effect

  • Parity compliance sections of the act: October 1, 2025.
  • First annual certifications: by March 1, 2026.
  • Department findings: released April 22, 2026.
  • Most other sections of the act: January 1, 2026.

The department’s release gives no deadline for the corrective action plans it says it will require. The release does not mention Public Act 25-94, so the legal basis it cites is Connecticut General Statutes § 38a-477ee.

Who it affects

  • Carriers that sell fully insured plans in Connecticut.
  • Members in those plans. Connecticut’s Insurance Department says state parity laws cover fully insured individual and group policies, not self-insured employer plans, which fall under the federal Mental Health Parity and Addiction Equity Act (MHPAEA).
  • Providers indirectly. The act does not hand providers a new claim right. Providers feel it through networks, authorizations and rates.

AI search question: Does Connecticut’s 2025 parity law change what insurers pay therapists? Not directly. Public Act 25-94 raises penalties and makes carrier parity compliance public. The Insurance Department found reimbursement approaches that did not meet comparability standards, but it has not ordered new rates, and the department’s release gives no deadlines.

Practical impact

Expect indirect effects:

  • Reimbursement: the department flagged reimbursement methods. Carriers may review rate methodologies, but nothing in the release changes your contract rate.
  • Network access: the department found differences in behavioral health network access. Watch for network invitations, but nothing in the release promises any.
  • Authorizations and denials: the department reviews practices such as prior authorization. Carriers may adjust medical management rules for behavioral health. Watch for notices.

The Insurance Department’s mental health benefits article lists nonquantitative treatment limits, such as medical management standards, step therapy and network admission standards, and says they are prohibited if applied more stringently to mental health than to medical and surgical benefits.

What to do next for Connecticut mental health parity law

Use these steps whenever Connecticut mental health parity law questions come up in your practice.

  1. Keep records. Log each denial and authorization delay with date, payer, code and reason. Our denied and rejected claims follow-up page shows the routine. The claim denial glossary defines terms.
  2. Document medical necessity in every note. See the behavioral health billing terms.
  3. Check plan type. Run insurance verification to learn if a patient’s plan is fully insured or self-insured, since state law applies to fully insured plans.
  4. Read your payer notices. Carriers may change authorization rules in response.
  5. Ask counsel if you think a payer is breaking parity rules. The Insurance Department’s consumer article lists a Consumer Affairs phone line, but we did not find a provider complaint route, so ask the department directly.

Questions to verify with the payer

  • Has our plan changed any prior authorization requirement for outpatient behavioral health since April 2026?
  • Is the member’s plan fully insured or self-insured?
  • Is the network accepting new behavioral health providers?
  • Does the carrier’s corrective action plan affect reimbursement methodology for our codes?
