Does Cigna Cover Drug and Alcohol Rehab?
The Cigna Group / Evernorth Behavioral Health
Checked against public plan documents on
Generally yes — Cigna plans typically include substance use disorder treatment, with behavioural health benefits administered through Evernorth. As with any insurer, the covered amount depends on the level of care, whether the provider is in network, and whether prior authorisation was obtained. The company name on the card tells you very little; the plan documents tell you everything.
Six questions that decide your bill
Ask these of member services, and write down the reference number of the call. Every answer below changes what you actually pay.
Is my behavioural health benefit administered by Evernorth, and which number do I call?
Behavioural health is often handled by a separate administrator with its own network and authorisation process.
Which levels of care are covered and which need prior authorisation?
Residential admission almost always requires documented medical necessity in advance.
Is the facility in network for this level of care?
Network participation is service-specific, not facility-wide.
What are my deductible, coinsurance and out-of-pocket maximum?
These three numbers define your realistic exposure for the year.
What is the initial authorisation length and the concurrent review schedule?
Knowing the review cadence lets you anticipate a denial before it arrives rather than after.
Are medications for opioid or alcohol use disorder covered under pharmacy or medical benefit?
Which benefit pays changes both the approval path and your cost share.
What federal law requires — and what it does not
The Mental Health Parity and Addiction Equity Act requires most group health plans and insurers that cover mental health and substance use disorder benefits to apply no stricter limits to them than to comparable medical and surgical benefits. That covers things like visit limits, prior authorisation practices and cost sharing. What the law does not do is require every plan to cover addiction treatment in the first place, guarantee that a specific facility is in your network, or prevent a plan from applying medical-necessity review. So the practical question is never "does insurance cover rehab" in general — it is what your specific plan covers, at which facilities, after which approvals.
If a claim is denied
A denial is not the end of the process. Plans subject to federal rules must provide a written explanation and an appeals process, typically including internal appeal and then external review by an independent body. Request the specific clinical criteria used in the decision — for substance use treatment these are often published criteria such as ASAM, and comparing your documented assessment against them is the substance of a successful appeal.

Common questions
Does Cigna cover residential rehab?
Many plans do, subject to prior authorisation and documented medical necessity. Confirm both before admission rather than after.
What if the facility says they "work with" Cigna?
That phrase can mean in-network, or it can mean they will bill your out-of-network benefit. Ask which one, in writing.
Does Cigna cover medication-assisted treatment?
Medications for opioid use disorder are generally covered, though formulary tier and authorisation requirements vary by plan.
