Understanding Cigna Rehab Coverage
Cigna Healthcare, now operating under The Cigna Group, is a global health services company serving millions of members across the United States. If you have Cigna insurance and are considering addiction treatment, understanding your coverage is an important first step. Most Cigna health plans cover substance use disorder treatment as required by the Affordable Care Act and the Mental Health Parity and Addiction Equity Act.
Cigna manages behavioral health benefits, including substance abuse treatment, through its Evernorth Behavioral Health division. This carve-out arrangement means that your addiction treatment benefits may be administered separately from your general medical benefits. When verifying coverage, it is important to contact Cigna Behavioral Health specifically, as general customer service representatives may not have detailed information about substance abuse benefits.
Coverage levels vary significantly depending on your plan type, your employer's benefit design, and whether you seek in-network or out-of-network care. The most generous Cigna plans for addiction treatment are typically PPO plans that provide both in-network and out-of-network benefits with reasonable cost-sharing structures.
What Cigna Plans Cover for Addiction Treatment
Cigna plans generally cover the full continuum of addiction treatment services, from initial assessment through aftercare. The specific services covered and the cost-sharing that applies depend on your particular plan, but most Cigna members have access to comprehensive substance abuse treatment benefits.
Medical Detoxification
Cigna covers medically supervised detoxification when it is determined to be medically necessary. Detox is typically covered as an inpatient service, with authorization based on the substance involved, the severity of dependence, and the risk of complications during withdrawal. Most Cigna plans cover detox lasting three to ten days depending on clinical need.
Authorization for detox through Cigna usually requires documentation of active substance use, withdrawal risk assessment, and a treatment plan. Cigna's utilization review team evaluates these factors against clinical criteria, typically ASAM guidelines, to determine medical necessity and the appropriate setting for detox services.
Residential Treatment
Residential or inpatient rehabilitation is covered by most Cigna plans when medically necessary. Cigna typically authorizes residential treatment for an initial period and then conducts concurrent reviews every few days to determine whether continued residential care is needed. The length of stay is based on clinical progress and ongoing medical necessity.
For in-network residential treatment, Cigna PPO members typically pay coinsurance of 10 to 30 percent after meeting their deductible. Out-of-network residential treatment is also covered under PPO plans but at higher cost-sharing rates. Trust SoCal in Orange County works with Cigna to obtain authorization and ensure seamless coverage for residential treatment.
Outpatient and Intensive Outpatient Programs
Cigna covers outpatient addiction treatment, including standard outpatient therapy, intensive outpatient programs, and partial hospitalization programs. Outpatient services typically require lower cost-sharing than residential treatment and may not require pre-authorization for standard therapy visits.
Intensive outpatient programs through Cigna usually involve nine or more hours of structured therapy per week. These programs are covered when clinically appropriate and provide a step-down level of care after residential treatment or as a primary treatment option for individuals who do not require 24-hour supervision.
How to Verify Your Cigna Benefits for Rehab
Verifying your Cigna benefits before beginning addiction treatment helps you understand your financial responsibility and avoids unexpected costs. The verification process involves contacting Cigna Behavioral Health and asking specific questions about your substance abuse treatment benefits.
To verify your benefits, call the number on the back of your Cigna insurance card and ask to be connected to behavioral health benefits. Have your member ID, group number, and date of birth ready. Ask about coverage for each level of care you may need, including detox, residential, PHP, IOP, and outpatient. Request specific information about deductibles, coinsurance rates, copayments, and out-of-pocket maximums for both in-network and out-of-network care.

Cigna Pre-Authorization for Rehab
Cigna requires pre-authorization for most levels of addiction treatment above standard outpatient therapy. Pre-authorization is the process by which Cigna reviews the clinical necessity of your proposed treatment before approving coverage. Failing to obtain pre-authorization can result in reduced benefits or complete denial of coverage.
The pre-authorization process typically begins with a clinical assessment by a licensed professional who submits documentation to Cigna Behavioral Health. Cigna reviews the assessment against clinical criteria, usually ASAM guidelines, and issues an authorization decision. Initial authorizations are typically for a defined period, after which continued stay reviews determine whether further treatment is warranted.
Treatment centers experienced with Cigna handle the pre-authorization process as part of their standard admissions workflow. Trust SoCal manages the entire authorization process for Cigna members, from initial submission through concurrent reviews, ensuring that clinical documentation supports continued coverage throughout your treatment stay.
Maximizing Your Cigna Addiction Treatment Benefits
Getting the most from your Cigna coverage for addiction treatment requires understanding your plan structure and making strategic decisions about provider selection and timing. Several strategies can help minimize your out-of-pocket costs while ensuring you receive the quality of care you deserve.
First, check whether you have met any portion of your annual deductible through other medical expenses this year. If you are close to meeting your deductible, beginning treatment can push you past that threshold quickly, reducing your cost-sharing for the remainder of care. Similarly, if you are approaching your out-of-pocket maximum, residential treatment costs may bring you to that limit, after which Cigna covers remaining services at 100 percent.
Second, use in-network providers whenever possible. Cigna's in-network rates for addiction treatment are negotiated and typically much lower than what out-of-network providers charge. In-network care also counts toward your in-network deductible and out-of-pocket maximum, which are usually lower than out-of-network limits. Trust SoCal maintains relationships with Cigna and can clarify your network status before admission.
What to Do If Cigna Denies Your Claim
Insurance claim denials for addiction treatment are frustrating but not uncommon. If Cigna denies coverage for all or part of your treatment, you have the right to appeal. Understanding the appeals process and your rights under federal and California law empowers you to fight for the coverage you deserve.
Cigna must provide a written explanation of any denial, including the specific clinical criteria used and the reason your treatment did not meet those criteria. Review this explanation carefully and compare it against ASAM guidelines. California SB 855 requires Cigna to use recognized clinical criteria for medical necessity determinations, so denials based on arbitrary or proprietary criteria may be challengeable.
If your internal appeal is unsuccessful, California residents can request an Independent Medical Review through the Department of Managed Health Care or the California Department of Insurance, depending on your plan type. IMR decisions are binding on the insurer, and studies show that a significant percentage of addiction treatment denials are overturned at the IMR level. Contact Trust SoCal at (949) 280-8360 for assistance navigating the Cigna appeals process.
