Getting prior authorization right with Cigna is not the same as getting it right with every other commercial payer. The administrative structure is different, the behavioral health arm is branded separately, and prior auth requirements for some levels of care have been evolving in ways many providers still haven’t fully internalized.cigna+1
Cigna’s behavioral health benefits — including substance use disorder services — are administered through Evernorth Behavioral Health, a health services division and subsidiary of The Cigna Group. When you’re calling for an auth, submitting clinicals, or appealing a denial, you’re working with Evernorth, not Cigna’s medical benefits team. That distinction matters for where you call, what portal you use, and which criteria are being applied.[static.cigna]
Here’s a practical breakdown of how Cigna (via Evernorth) determines medical necessity for addiction treatment, how ASAM is used in utilization review, and what the current prior auth landscape looks like by level of care.
How Cigna Uses ASAM Criteria for Medical Necessity
Cigna and Evernorth formally use The ASAM Criteria as the guideline set for substance use disorder level-of-care medical necessity reviews. Evernorth’s published standards state that The ASAM Criteria, developed by the American Society of Addiction Medicine, are used to conduct medical necessity reviews for SUD treatment levels of care, rather than proprietary placement tools.evernorth+2
As of late 2024, Evernorth uses The ASAM Criteria, 3rd Edition for all customers and has announced adoption of The ASAM Criteria, 4th Edition for adults 18+ while continuing 3rd Edition for some younger members. ASAM is widely recognized as the national standard for placement, continued stay, and discharge decisions in addiction treatment, using a six-dimension, biopsychosocial assessment framework.providernewsroom+2
In practice, this means:
Initial auth requests, concurrent reviews, and appeals for SUD treatment are expected to be framed in ASAM language and dimensions.
Evernorth’s internal criteria crosswalk directly to ASAM’s six dimensions and levels of care, rather than adding a competing proprietary level-of-care algorithm for SUD.cigna+1
For mental health (non-SUD) conditions, Evernorth typically uses other guideline sets (such as MCG) rather than ASAM.evernorth+1
Clinically, that’s a win for providers: your placement arguments and documentation can lean directly on ASAM’s published criteria and dimensional framework, which are publicly available and widely used across the field.americanaddictioncenters+1
The Evernorth Administrative Layer: What Providers Need to Know
Evernorth Behavioral Health is both Cigna’s behavioral network manager and a standalone behavioral health solutions vendor for some non-Cigna plans, which means members with other medical carriers may still route behavioral benefits through Evernorth. Always check the back of the insurance card for behavioral health contacts.[static.cigna]
Key operational points for providers include:evernorth+3
Provider portals:
CignaforHCP.com (Cigna-branded) and Provider.Evernorth.com (Evernorth-branded) for eligibility, auth submissions, and claims.
Inpatient/detox/residential/PHP authorizations:
Evernorth Inpatient Prior Authorization Form (for inpatient mental health, detox, SUD rehab, dual diagnosis, and eating disorders) is available on Provider.Evernorth.com.evernorth+1
For other higher levels of care, including residential and PHP, Evernorth instructs providers to call 800‑926‑2273.providernewsroom+1
Care manager assignment:
For higher levels of care, Evernorth typically assigns a behavioral health care manager who coordinates concurrent reviews and discharge planning.[static.cigna]
Operationally, once a member is admitted at a higher level of SUD care, the assigned care manager becomes your go-to for concurrent reviews and continued-stay authorizations, rather than the initial intake team. Building a working relationship with that care manager and proactively communicating ASAM-dimensional updates and step-down planning tends to improve review outcomes.[static.cigna]
Prior Authorization Requirements by Level of Care
Prior auth policies are benefit-plan–dependent and can vary by employer group, but several broad changes and patterns have been published.
Intensive Outpatient (IOP): Prior Auth Removed for Most Plans
Evernorth issued guidance stating that, starting May 1, 2022, prior authorization is no longer required for the intensive outpatient (IOP) level of care for many plans, and that in-network providers should not submit prior auth forms for IOP services. This applies to behavioral health IOP, including SUD IOP, under most standard Evernorth arrangements, although some plan designs can still differ.[static.evernorth]
Practically, that means:
Members can start IOP without waiting for a prospective auth decision.
Claims are still subject to medical necessity review, so documentation aligning with ASAM dimensions remains essential.
Some plans, carve-outs, or legacy arrangements may still require auth, so Evernorth instructs providers to verify benefit specifics.evernorth+1
Partial Hospitalization (PHP): Prior Auth Removed for Most Plans as of January 2025
Evernorth announced that effective January 1, 2025, prior authorization will no longer be required for partial hospitalization (PHP) level of care for patients with coverage under most Evernorth plans, with a small number of plans continuing to require PA.[providernewsroom]
Key details from that communication:[providernewsroom]
The change is intended to reduce administrative burden and support timely access to PHP care.
Dates of service before January 1, 2025, may still require prior auth under previous rules.
Providers are advised to contact Provider Services with questions and to verify whether a specific plan still requires PA.
Operationally, PHP admissions can typically proceed without prior auth for most Evernorth-administered plans as of 2025, but PHP stays remain subject to concurrent review and retrospective medical necessity review at the claims level.evernorth+1
Residential SUD (ASAM 3.1–3.7): Prior Auth Generally Required
For residential and certain other higher levels of care, Evernorth directs providers to call Provider Services (800‑926‑2273) to request authorization and discuss benefit-specific requirements. Coverage policies and medical-necessity guidelines for SUD levels of care reference ASAM levels and emphasize matching level of care to clinical severity and recovery environment.evernorth+3
For residential SUD treatment, Evernorth’s ASAM-based criteria typically focus on:
Severity of use and inability to maintain abstinence at lower levels of care (Dimensions 1 and 5).
Biomedical and psychiatric comorbidities that require 24‑hour support or monitoring (Dimensions 2 and 3).americanaddictioncenters+1
Recovery environment problems that make outpatient treatment unsafe or ineffective (Dimension 6).evernorth+1
The most persuasive residential auth requests clearly document unsuccessful attempts at lower levels of care, current relapse risk, and a recovery environment that is dangerous, unsupportive, or substance-saturated.
Acute Inpatient and Inpatient Detox (ASAM 3.7‑WM / 4‑WM): Prior Auth & Notification
Evernorth’s Inpatient Prior Authorization Form is used for initial requests for inpatient behavioral health and substance use services, including inpatient detox, inpatient SUD rehabilitation, dual diagnosis, and inpatient mental health stays. The form and accompanying guidelines stress that it should be completed by a clinician with direct knowledge of the patient’s current presentation and treatment history.evernorth+1
Typical clinical elements required for SUD inpatient/detox auth include:americanaddictioncenters+1
Substances used, pattern of use, and date/time of last use (Dimension 1).
Withdrawal risk and current withdrawal scores (e.g., CIWA, COWS) if applicable.
Co-occurring medical conditions and medications (Dimension 2).
Co-occurring psychiatric symptoms, suicidality, psychosis, or cognitive impairment (Dimension 3).
Prior treatment episodes and relapse patterns (Dimension 5).
Recovery environment and safety concerns (Dimension 6).
Emergency behavioral health admissions generally do not require prior authorization at the point of emergency care, but Evernorth expects prompt notification (often within one business day) if an emergency leads to inpatient admission, consistent with many commercial plan policies.[static.cigna]
The Six ASAM Dimensions in Cigna/Evernorth Utilization Review
Evernorth’s ASAM-based medical necessity reviews are built around ASAM’s six dimensions, which provide a whole-person, multidimensional view of risk and needs.asam+1
Under The ASAM Criteria (3rd and 4th Editions), the dimensions are commonly described as:asam+2
Dimension 1 — Acute Intoxication and/or Withdrawal Potential
Current intoxication, withdrawal history and severity, need for withdrawal management, and risk of severe or complicated withdrawal.
Dimension 2 — Biomedical Conditions and Complications
Co-occurring medical conditions that require monitoring or interfere with SUD treatment (e.g., unstable cardiac disease, seizures, pregnancy complications).
Dimension 3 — Emotional, Behavioral, or Cognitive Conditions and Complications
Co-occurring mental health disorders, cognitive limitations, suicidality, self-harm, aggression, or behavioral dysregulation that impact treatment needs.
Dimension 4 — Readiness to Change (emphasized more as a modifier in ASAM 4.0)
Motivation, insight, ambivalence, and engagement in change efforts.
Dimension 5 — Relapse, Continued Use, or Continued Problem Potential
History and likelihood of continued use or relapse, prior treatment episodes, coping skills, and internal/external triggers.
Dimension 6 — Recovery/Living Environment / Person-Centered Considerations
Housing stability, exposure to substances, social supports, family dynamics, practical barriers, and safety in the environment.
ASAM’s multidimensional assessment informs level-of-care recommendations across a continuum from early intervention to outpatient, IOP, PHP, residential levels (3.1–3.7), and medically managed inpatient services (Level 4). Evernorth’s medical necessity criteria explicitly tie SUD placement and continued stay decisions to these dimensions.providernewsroom+4
For providers, that means every clinical summary submitted to Evernorth should map patient data to these six dimensions, rather than listing symptoms and diagnoses without a dimensional framework.
MAT Coverage Through Cigna/Evernorth
Cigna/Evernorth covers medications for addiction treatment (MAT) — including medications for opioid use disorder and alcohol use disorder — as part of its behavioral health and pharmacy benefits, but prior authorization and step-therapy requirements vary by drug and plan design.cms+1
General patterns across many Cigna/Evernorth commercial products (always verify by plan):cigna+1
Buprenorphine-containing products (e.g., buprenorphine/naloxone):
Often covered as preferred medications for OUD, with PA requirements reduced or streamlined on many plans, particularly in line with national moves to ease buprenorphine access.
Some plans still require documentation of OUD diagnosis and treatment plan details.
Naltrexone (oral, and extended-release injectable):
Typically covered for alcohol use disorder and sometimes OUD; extended-release injectable formulations (e.g., Vivitrol) may require PA or step therapy due to higher cost.
Methadone for OUD:
Covered when dispensed through federally certified opioid treatment programs (OTPs), consistent with federal regulations; coverage and billing flows through OTP contracts and state/federal regulations more than through standard behavioral auth processes.[cms]
Naloxone:
Widely covered as an overdose reversal medication, often without PA, though quantity and refill limits can vary.
Because MAT coverage is highly plan-specific and frequently updated, Cigna/Evernorth directs providers to verify formulary status, PA requirements, and quantity limits through online tools or the behavioral health/contact number on the back of the member’s ID card.cigna+1
Concurrent Reviews and Continued-Stay Authorization
For levels of care that still require prior authorization (e.g., most residential programs and inpatient detox), Evernorth conducts concurrent reviews to determine continued-stay medical necessity.providernewsroom+2
Typical patterns include:
Inpatient/detox:
Short review cycles, often every 2–3 days, focused on stability, withdrawal progress, and readiness for step-down.[static.cigna]
Residential:
Reviews more commonly weekly or biweekly, evaluating treatment response, engagement, and whether step-down criteria are approaching.evernorth+1
Even in settings where prior auth has been removed (e.g., PHP and IOP under most plans), Evernorth may still perform periodic utilization reviews or post-service claim audits, especially if length of stay or utilization appears atypical when compared to norms.providernewsroom+1
Strong concurrent review submissions usually include:
Updated ASAM dimensional ratings and brief rationale for each.
Objective indicators of progress or risk (recent use, cravings, safety events, therapy participation).
Clear, time-bound step-down plans and aftercare arrangements.
Reviewers are looking for clinical evidence that the current level of care remains the least intensive, safe, and effective option — a central ASAM principle — and that discharge planning is active rather than an afterthought.asam+1
Peer-to-Peer Reviews: How to Use Them Effectively
When Evernorth issues an adverse determination (e.g., denying admission or reducing approved days), providers typically have the option to request a peer-to-peer review with an Evernorth physician reviewer before or in parallel with a formal appeal.evernorth+1
To use peer-to-peer effectively:
Come prepared with a concise ASAM-dimensional summary and level-of-care rationale.
Highlight Dimensions 1, 2, 3, 5, and 6 as they relate directly to level of care selection and risk.
Clarify the patient’s prior treatment history, including unsuccessful lower-level attempts.
Articulate a step-down plan and what specific criteria you expect to see before transitioning.
Framing your argument in ASAM terms — for example, emphasizing high relapse potential with repeated IOP failures (Dimension 5) and a dangerous or unstable living environment (Dimension 6) that prevents safe outpatient treatment — aligns directly with the criteria Evernorth says it uses for SUD placement decisions.evernorth+2
FAQ: Cigna/Evernorth Medical Necessity and Addiction Treatment Authorization
1. Does Cigna require prior authorization for IOP substance use disorder treatment?
For many Evernorth-administered plans, prior authorization is not required for intensive outpatient (IOP) behavioral health services as of May 1, 2022, and providers are instructed not to submit IOP prior auth forms. However, Evernorth notes that authorization requirements can depend on the specific benefit plan, so providers should still verify coverage for each member.evernorth+1
2. Does Cigna require prior authorization for PHP substance use disorder treatment?
Effective January 1, 2025, Evernorth announced that prior authorization will no longer be required for partial hospitalization (PHP) level of care for most Evernorth plans. A small subset of plans will still require auth, and services rendered before that date follow prior rules, so checking benefit details remains important.providernewsroom+1
3. Does Cigna/Evernorth use ASAM for all addiction treatment levels of care?
Yes. Evernorth’s materials state that The ASAM Criteria are used to guide medical necessity reviews for substance use disorder levels of care across the continuum, serving as the framework for placement, continued stay, and discharge decisions. For mental health conditions, other guideline sets are used, but for SUD, ASAM is the operative standard.providernewsroom+2
4. How do I request authorization for residential or inpatient SUD treatment with Cigna/Evernorth?
For inpatient behavioral health and substance use services (including detox and inpatient SUD rehab), providers use the Evernorth Inpatient Prior Authorization Form or call the listed behavioral health number; for other higher levels of care such as residential and PHP, Evernorth directs providers to call 800‑926‑2273 for authorization and benefit verification.evernorth+2
5. Are medications for opioid use disorder covered under Cigna plans administered by Evernorth?
Cigna/Evernorth covers medications for opioid use disorder (e.g., buprenorphine, methadone via OTPs, naltrexone) and alcohol use disorder under pharmacy and behavioral benefits, but prior authorization and step-therapy rules vary by medication and benefit plan. Providers should check the specific plan formulary and PA criteria and can use the behavioral health or pharmacy numbers on the member’s ID card for clarification.cms+1
6. Where can I find Cigna/Evernorth’s medical necessity criteria and prior authorization resources?
Evernorth publishes behavioral health medical necessity criteria, ASAM criteria information, and prior authorization/billing guides in its online provider resource library. Providers can access these materials via the Evernorth provider website (Provider.Evernorth.com) and Cigna’s coverage policies site, which outline current criteria and authorization requirements.providernewsroom+3
Getting Your Behavioral Health Program’s Payer Infrastructure Right
Understanding how Cigna/Evernorth applies ASAM criteria and manages prior authorization is just one part of building a sustainable addiction treatment program. Commercial payer contracting, credentialing, clinical documentation, billing compliance, and multi-payer authorization workflows all have to function together if your program is going to be financially and operationally viable.
ForwardCare is a behavioral health MSO that partners with clinicians, sober living operators, entrepreneurs, and investors to launch and scale IOP and PHP programs. They handle the business infrastructure — insurance credentialing, billing, compliance, licensing support, and operational setup — so partners can focus on clinical quality and program growth instead of payer administration.
If you’re building or expanding a behavioral health program and want the business side handled by people who live in this space every day, it’s worth a conversation.
