TL;DR: Cigna Healthcare modified policy UM-35 governing Transition of Care service requests for new customers, effective October 1, 2025. Here's what changes for billing teams.
Cigna Healthcare updated UM-35 (um35-transition-of-care-service-requests-for-new-customers) to establish a consistent process for evaluating and responding to Transition of Care requests from new enrollees. This coverage policy does not list specific CPT, HCPCS, or ICD-10 codes, but it directly shapes how prior authorization requests are handled during a member's first days on a new Cigna plan. If your practice serves patients who recently switched to Cigna, this policy change affects your reimbursement timeline and claim denial risk starting October 1, 2025.

Cigna Transition of Care Coverage Policy: What UM-35 Covers and Who It Affects in 2025
The Cigna Transition of Care coverage policy under UM-35 exists for one core reason: when a patient switches to a Cigna plan mid-treatment, their prior coverage history doesn't automatically carry over. UM-35 creates the process Cigna uses to decide whether ongoing services will be covered while the new member transitions to in-network care or awaits a medical necessity determination.
This matters most for patients who switch employers, age onto a new plan, or move from Medicaid to commercial coverage. These patients often arrive at your practice already mid-course — on an active chemo protocol, in a post-surgical recovery program, or managing a chronic condition with a specialist outside Cigna's network.
Without a successful Transition of Care request, those services face prior authorization gaps. That gap translates directly into delayed reimbursement or outright claim denial. UM-35 is the policy that governs how Cigna adjudicates those requests.
The effective date of October 1, 2025 means Cigna is standardizing this process — likely because inconsistent handling across regions or plans created disputes. A modified policy means the old approach had variability. The new one is designed to be uniform.
Cigna Transition of Care Medical Necessity Requirements and Coverage Criteria 2025
What Cigna's UM-35 Policy Is Designed to Do
The stated purpose of UM-35 is to establish a consistent process for evaluating and responding to Transition of Care requests for new enrollees. That phrase — "consistent process" — is doing a lot of work here.
It signals that Cigna is moving away from case-by-case discretion at the local level. Your billing team should treat this as a more structured, rules-based review. That's good news if you document well. It's bad news if your Transition of Care requests have been informal or verbal.
Medical necessity still sits at the center of every Transition of Care request. Cigna will evaluate whether the ongoing service — the one that was already authorized or initiated under the patient's prior plan — meets its own medical necessity standards. Don't assume that prior authorization from another payer transfers or accelerates Cigna's review.
What the Policy Does Not Specify
UM-35 does not list specific CPT or HCPCS codes. The policy applies broadly to any service that a new enrollee is receiving when they join Cigna. That includes physician services, specialist visits, ongoing therapies, DME, infusions, and surgical follow-up — whatever was in progress.
This is actually where things get complicated. Because there are no code-level restrictions defined in the policy text, your billing team has to apply Transition of Care billing guidelines to the full scope of services the patient is receiving. You're not dealing with a narrow procedure-specific rule. You're dealing with a process rule that touches every active claim for every new enrollee.
Cigna Transition of Care Exclusions and Non-Covered Indications
The policy summary does not define explicit exclusions by service type or diagnosis. Cigna does not enumerate non-covered procedures within UM-35 itself.
That said, Transition of Care coverage is not unlimited. Cigna's standard medical necessity criteria still apply to each underlying service. If a procedure wouldn't be covered for an established member, Transition of Care status doesn't make it covered for a new one.
The real risk area is timing. Transition of Care protections are temporary by design. Once the transition period ends, the patient falls under Cigna's standard prior authorization requirements. If your billing team doesn't track when Transition of Care authorizations expire, you'll generate claims against a dead authorization.
Coverage Indications at a Glance
The policy summary does not provide indication-level coverage criteria with associated codes. The table below reflects what UM-35 does describe at a process level.
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Ongoing services initiated under prior plan, new Cigna enrollee | Eligible for Transition of Care review | Not specified by UM-35 | Must submit formal request; medical necessity evaluated under Cigna's standard criteria |
| Services where Transition of Care period has lapsed | Standard prior auth rules apply | Not specified | Do not continue billing under ToC authorization past expiration |
| Services not meeting Cigna medical necessity criteria | Not covered regardless of ToC status | Not specified | Prior approval from another payer does not override Cigna's determination |
Cigna Transition of Care Billing Guidelines and Action Items for 2025
What Your Team Needs to Do Before October 1, 2025
| # | Action Item |
|---|---|
| 1 | Audit your new Cigna enrollee intake process now. Before October 1, 2025, make sure your front desk and billing team identify new Cigna members at check-in. Flag any patient who has been on Cigna for fewer than 90 days and is mid-treatment. These patients are your UM-35 exposure. |
| 2 | Submit Transition of Care requests at the first visit, not after a denial. Don't wait for a claim to reject before you request Transition of Care review. Cigna's UM-35 process is triggered by a formal request. If you're not submitting one proactively, you're leaving the authorization gap open. |
| 3 | Document the prior plan and prior authorization in writing. When you submit a Transition of Care request, include the member's prior plan information, the services already in progress, and any prior authorization from the previous payer. Cigna will evaluate medical necessity independently, but documentation of prior coverage strengthens the request. |
| 4 | Track expiration dates on every Transition of Care authorization. This is where most practices bleed money. Transition of Care authorization has a fixed window. When it expires, the patient falls back under standard prior authorization rules. Build a tickler or workflow trigger so your billing team knows when each ToC authorization ends. |
| 5 | Train your authorization staff on the modified process before the effective date. UM-35 was modified — that means the old process your team knows may not match what Cigna expects after October 1, 2025. Request updated Transition of Care request forms or process documentation from your Cigna provider relations contact before the effective date. |
| 6 | Don't assume verbal Transition of Care approvals are binding. With a formalized, consistent process under UM-35, written authorization is the only safe documentation. Verbal approvals from a Cigna representative do not constitute prior authorization. Get it in writing every time. |
| 7 | Review your claim denial data for Transition of Care patterns. Pull your Cigna denials from the past 12 months. Look for denial codes tied to authorization, non-covered services, or plan non-participation. If you see a cluster around new enrollees, that's your UM-35 exposure quantified. Fix the workflow before October 1. |
If your practice has a high volume of new Cigna enrollees — particularly if you're near an employer open enrollment window or serve a population with frequent plan changes — talk to your compliance officer or billing consultant before the effective date. The lack of code-specific guidance in UM-35 means the policy applies broadly, and the financial exposure varies significantly by specialty and service mix.
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for Transition of Care Under um35-transition-of-care-service-requests-for-new-customers
Cigna's UM-35 policy does not list specific CPT, HCPCS, or ICD-10 codes. The policy governs a process — how Transition of Care requests are evaluated — rather than a specific procedure or diagnosis category.
This is an important distinction for your billing team. UM-35 applies to any active service a new enrollee is receiving. There is no defined code set to audit against. Every claim for a new Cigna member in active treatment falls within the scope of this policy until their Transition of Care period resolves.
Because no codes are specified, your team cannot rely on code-level filtering to identify UM-35 exposure. The trigger is member status — new enrollee, mid-treatment — not procedure type.
What this means operationally: Your intake workflow and eligibility verification process carry the full weight here. If your team doesn't identify new Cigna enrollees at the point of service, no billing system flag will catch it for you.
