How to Check Benefits for Addiction & Dual Diagnosis Treatment

Navigating health insurance for addiction treatment is one of the most stressful parts of getting help. This guide explains exactly what Cigna covers for substance use disorder (SUD) and dual diagnosis treatment, what it typically costs, how to verify your benefits, and what to do if coverage is denied.
Whether you’re exploring care for yourself or a loved one, Iris Healing’s admissions team can verify your Cigna benefits at no cost and walk you through your options before you make any decisions.

Health net Coverage at a Glance

TL;DR: Yes, most Cigna plans cover addiction treatment — including detox, residential, PHP, IOP, and MAT — when care is deemed medically necessary. What you pay out of pocket depends on your plan type, deductible, and whether the facility is in-network. Prior authorization is required for most residential and intensive levels of care. If you’re denied, you have the right to appeal.

Key Takeaways

  • Yes, Cigna covers addiction treatment — most Cigna plans cover medically necessary SUD treatment, including detox, IOP, PHP, residential, and MAT.
  • Medical necessity is the primary gating factor — Cigna must determine that the requested level of care is clinically appropriate before authorizing treatment.
  • Verification before admission is essential — call member services or use a treatment center’s admissions team to confirm exact benefits before starting care.
  • Coverage varies significantly by plan type — out-of-pocket costs, prior authorization requirements, and network rules differ across HMO, PPO, and marketplace plans.
  • The MHPAEA requires parity — federal law prohibits Cigna from applying more restrictive limits to behavioral health benefits than to comparable medical benefits.
  • Iris Healing verifies Cigna benefits at no cost — contact our admissions team to start your verification.

What substances does Cigna cover treatment for?

Cigna-covered SUD treatment is not limited to alcohol and opioids. Coverage applies to any clinically diagnosed substance use disorder, including alcohol, opioids, stimulants (cocaine, methamphetamine), benzodiazepines, and cannabis. Coverage is determined by clinical diagnosis code — a licensed clinician must document the diagnosis.
Yes. Most Cigna plans cover medically necessary substance use disorder (SUD) treatment, including detox, outpatient therapy, intensive outpatient programs (IOP), partial hospitalization programs (PHP), residential treatment, and medication-assisted treatment (MAT). The exact services covered, the cost to you, and the authorization steps required depend on your specific plan.
Two federal laws require coverage parity for behavioral health:

The Mental Health Parity and Addiction Equity Act (MHPAEA) prohibits group health plans from applying more restrictive financial limits or treatment limitations to SUD benefits than to comparable medical/surgical benefits.

The Affordable Care Act (ACA) requires all non-grandfathered individual and small group marketplace plans to cover mental health and SUD treatment as one of ten essential health benefits.

These protections mean Cigna cannot categorically exclude addiction treatment — but they do not determine how much is covered or at what cost. That depends on your plan.

What Cigna Typically Covers for Addiction Treatment

Iris Healing treats substance use disorders across a full continuum of care — medically supervised detox, residential treatment, PHP, and IOP — with or without a co-occurring mental health diagnosis. Cigna plans cover six main levels of addiction treatment. Coverage at each level is contingent on medical necessity.

Level of Care What It Is Covered by Cigna? Common Requirements
Medical detox Supervised withdrawal management, usually 3–10 days Yes, when medically necessary Prior authorization; clinical documentation of withdrawal risk
Residential treatment 24/7 structured inpatient care, typically 28–90 days Yes, when medically necessary Prior authorization; ongoing clinical reviews every few days
Partial Hospitalization (PHP) Day treatment, ~6 hours/day, 5 days/week Yes Prior authorization for most plans
Intensive Outpatient (IOP) Structured therapy, ~3 hours/day, 3–5 days/week Yes Prior authorization on some plans
Telehealth / Virtual IOP Remote IOP via secure video platform Yes, on most plans post-2020 Prior authorization mirrors in-person IOP requirements
Standard outpatient therapy Individual or group therapy, weekly sessions Yes Referral required on HMO plans
Medication-Assisted Treatment (MAT) FDA-approved medications (buprenorphine, naltrexone) Yes, subject to formulary Step therapy or prior authorization may apply
Aftercare / step-down care IOP, outpatient therapy, or MAT maintenance following primary treatment Yes, when medically necessary New PA request required
  • ⚠ Detox safety note: Alcohol and benzodiazepine withdrawal can be life-threatening. Medically supervised detox is not optional for high-risk cases. Opioid withdrawal carries significant relapse risk in the first 24–72 hours without MAT support.

What "Medical Necessity" Means for Behavioral Health

  • Medical necessity means a clinician has determined that a specific level of care is the minimum appropriate for safe, effective treatment. Cigna will not authorize addiction treatment — or continued treatment — unless the requesting provider documents that the care meets this standard.
  • Cigna typically applies the ASAM (American Society of Addiction Medicine) criteria when reviewing behavioral health authorizations. Key factors Cigna considers include:
  • Severity of the substance use disorder (diagnosis, duration, frequency)
  • Co-occurring mental health conditions
  • Withdrawal risk and need for medical monitoring
  • Prior treatment history and response to lower levels of care
  • Current living environment and support system
  • Patient’s ability to engage in a lower level of care safely
  • The treating provider — not the patient — submits documentation to establish medical necessity. Iris Healing’s doctorate-level clinical team handles this process on behalf of admitted clients and manages all continued-stay reviews throughout treatment.

What Cigna Addiction Treatment Typically Costs out of Pocket

Out-of-pocket costs depend on four variables: your plan tier, your deductible, your co-insurance rate, and whether the facility is in-network.

Marketplace Plan Tiers (Individual/Family Plans)

Plan Tier Cigna Pays (approx.) You Pay (approx.) Typical Monthly Premium
Bronze 60% 40% Lowest
Silver 70% 30% Moderate
Gold 80% 20% Higher
Platinum 90% 10% Highest

Key Cost Terms Defined

  • Deductible — the amount you pay out of pocket before insurance begins covering costs. Annual deductibles for behavioral health vary widely: in-network deductibles on employer plans commonly range from $0–$3,000; out-of-network deductibles can be $3,000–$7,500 or higher.
  • Co-pay — a fixed amount per visit (e.g., $30 per outpatient therapy session), separate from co-insurance.
  • In-network vs. out-of-network — using an in-network facility typically reduces your cost-sharing significantly. Out-of-network care on a PPO plan may be covered at 50–60% after a separate, higher out-of-network deductible. HMO and EPO plans generally do not cover out-of-network care at all, except in emergencies.
  • Co-insurance — after meeting your deductible, you pay a percentage of each covered service. An 80/20 split means Cigna pays 80%, you pay 20%.
  • Out-of-pocket maximum — the annual cap on what you pay. Once reached, Cigna covers 100% of in-network covered services for the rest of the plan year. ACA plans cap out-of-pocket maximums annually (2024: $9,450 for individuals, $18,900 for families).
  • Contact Iris Healing’s admissions team to confirm your specific out-of-pocket costs before admission.

Cigna Plan Types and How They Affect Rehab Access

Your Cigna plan type determines which facilities you can use, whether you need referrals, and how much out-of-network care costs.
Plan Type Referral Required? Out-of-Network Coverage? Best For
HMO Yes (PCP referral) No (emergency only) Lower-cost, in-network-only care
PPO No Yes (higher cost-sharing) Flexibility to choose any provider
EPO No No (emergency only) Mid-range cost, no referrals but network-only
POS Yes (PCP referral) Yes (higher cost-sharing) HMO with out-of-network option
  • For addiction treatment, a Cigna PPO plan offers the most flexibility. Cigna PPO plan holders from outside California can access Iris Healing’s Woodland Hills programs using out-of-network benefits; our admissions team confirms your specific cost-sharing before admission.
Employer-Sponsored vs Marketplace Plans
Employer-sponsored plans may include Employee Assistance Program (EAP) benefits — a separate, confidential counseling and referral service that does not appear on your medical claims. If your employer offers an EAP, it can be a private first step before engaging your medical benefits.
Evernorth is Cigna’s health services subsidiary. Many Cigna employer plans route behavioral health benefits through Evernorth rather than through Cigna directly. If your Explanation of Benefits (EOB) or a denial letter references Evernorth, your behavioral health benefits are administered by Evernorth — but the same MHPAEA parity rules apply.
When verifying benefits, ask specifically: “Are my behavioral health benefits administered by Evernorth or directly by Cigna?” Prior authorization requests for behavioral health may need to be submitted to Evernorth, not standard Cigna member services.
  • Locate your Cigna member ID card. The card shows your plan name, group number, member ID, and the member services phone number.
  • Log in to myCigna.com (or the myCigna mobile app) to view your Summary of Benefits and Coverage (SBC), deductible status, and provider directory.
  • Search for the facility or provider using the myCigna provider directory. Confirm the exact network name matches your ID card — Cigna operates multiple networks.
  • Call Cigna member services (number on the back of your ID card) and ask: Is Iris Healing in-network under my specific plan? What is my in-network deductible and co-insurance for behavioral health? Is prior authorization required for residential, PHP, or IOP? What is my current deductible balance?
  • Call the treatment center’s admissions team. Ask them to run an insurance verification — most treatment centers, including Iris Healing, do this at no cost and will provide a written summary of benefits.
  • Request a reference number for every call. Document the date, representative name, and what was confirmed.
  • Iris Healing handles steps 3–6 on your behalf — at no cost, no obligation, fully confidential.

Prior authorization (PA) is Cigna’s advance-approval process for certain services. Without it, a claim may be denied even if the service is otherwise covered.
For behavioral health and addiction treatment, prior authorization is commonly required for:
  • Inpatient and residential admissions
  • Partial hospitalization (PHP)
  • Some intensive outpatient (IOP) admissions
  • MAT medications (some require step therapy — trying a lower-cost option first)
  • Extended lengths of stay beyond the initially authorized period
  • The treating provider submits a PA request with clinical documentation (diagnosis, ASAM level, treatment plan, expected length of stay).
  • Cigna reviews the request against its medical necessity criteria — typically within 24–72 hours for urgent requests and up to 15 calendar days for standard requests, though state regulations vary.
  • Cigna issues an approval (for a specified number of days or sessions), a request for more information, or a denial.

After completing residential or PHP care, Cigna may authorize continued care at a lower level — IOP, outpatient therapy, or MAT maintenance — when medical necessity continues. Step-down authorization is treated as a new PA request.

Iris Healing coordinates step-down transitions directly with Cigna to minimize interruptions. See our aftercare and relapse prevention program for what post-treatment support looks like.

A denial is not the end of the road. You have three levels of appeal:
  • Internal appeal — request that Cigna reconsider the denial. Submit additional clinical documentation. Cigna must respond within regulated timeframes (typically 30 days for standard, 72 hours for urgent).
  • External review — if the internal appeal is denied, you can request an independent external review by a third party not affiliated with Cigna. This right is guaranteed under the ACA.
  • State insurance commissioner — file a complaint with your state’s insurance regulator if the denial appears to violate parity law or plan terms.
If treatment is clinically urgent and Cigna has denied coverage, do not delay care. Iris Healing’s admissions team can submit an expedited appeal, initiate a single case agreement (SCA), identify state-funded options, or discuss self-pay arrangements.

A Cigna denial does not mean treatment is out of reach. Options include:
  • Self-pay with a payment plan — Iris Healing’s admissions team can discuss payment arrangements
  • Single case agreement (SCA) — a one-time negotiated exception allowing Cigna to cover an out-of-network facility at agreed rates; initiated by the treatment center
  • California Drug Medi-Cal (DMC-ODS) — publicly funded SUD treatment for eligible California residents; contact your county behavioral health department to screen for eligibility
  • Co-occurring disorder treatment resources — additional program options for individuals with dual diagnosis needs

COBRA Within 60 days of losing employer coverage Retroactive to loss-of-coverage date
Medicaid Any time if eligible Often same day or within days

California-Specific Insurance Rules for Cigna Members

  • SB 855 (effective 2021) requires all fully insured California health plans to cover medically necessary mental health and SUD treatment based on generally accepted standards of care — not proprietary utilization management criteria.
  • California Mental Health Parity Act adds state-level enforcement on top of federal MHPAEA protections.
  • California Cigna members whose claims are denied have additional appeal rights through the California Department of Managed Health Care (DMHC) or Department of Insurance (CDI).
  • Important exception: Self-funded employer plans governed by ERISA are exempt from California state law. Check whether your employer plan is self-funded — if it is, only federal MHPAEA protections apply.
