TL;DR: Cigna Healthcare modified UM-35, its transition of care coverage policy for new enrollees, effective October 1, 2025. Here's what billing teams need to know before claims start moving through the new process.
Cigna Healthcare updated policy UM-35 — "Transition of Care Service Requests for New Customers" — with an effective date of October 1, 2025. This coverage policy governs how Cigna evaluates and responds to transition of care requests when a patient newly joins a Cigna plan. No specific CPT or HCPCS codes are listed in the published policy data, but the operational and prior authorization implications are real, and they affect any specialty billing through a new Cigna enrollment period.

Cigna Transition of Care Coverage Policy: Coverage Criteria and Medical Necessity Requirements 2025
The core purpose of UM-35 is to create a consistent process for evaluating transition of care requests. That sounds administrative, but the billing consequences are concrete.
When a patient switches to a Cigna plan mid-treatment — mid-chemotherapy, mid-pregnancy, mid-surgical episode — they can request a transition of care period. During that window, Cigna is supposed to allow continuity with an out-of-network provider or ongoing authorization to continue a treatment that was approved under their prior plan. The modified UM-35 policy sets the rules for how Cigna evaluates those requests.
The real issue here is medical necessity. A transition of care request isn't automatically approved. Cigna evaluates whether the ongoing treatment meets its medical necessity criteria under the new plan. If your patient is mid-course on a therapy that's covered differently — or not covered at all — under their new Cigna benefit structure, that's where denials originate.
Prior authorization is directly tied to this policy. Treatments that required prior auth under the patient's previous plan may need a new authorization under the Cigna plan, even if a transition period is granted. Don't assume an active authorization from a prior insurer carries forward. It doesn't.
Cigna Transition of Care Billing Guidelines and Action Items 2025
This is where the rubber meets the road. The UM-35 modification takes effect October 1, 2025. Here's what your billing team needs to do before and after that date.
| # | Action Item |
|---|---|
| 1 | Audit your new Cigna enrollees now. Pull a list of patients who joined Cigna plans after a recent open enrollment or special enrollment period. Flag anyone who is mid-treatment. These are your highest-risk accounts for transition of care billing issues. |
| 2 | Confirm active transition of care requests before October 1, 2025. If any of your patients have pending or active transition of care requests with Cigna, confirm their status before the effective date. The modified policy may change how Cigna processes requests already in the queue. |
| 3 | Re-verify prior authorization status for transitioning patients. Do not rely on authorization numbers from a previous payer or a previous plan year. Call Cigna or check the portal to confirm whether a new prior auth is needed under the current benefit structure. |
| 4 | Update your registration and intake workflows. Your front desk and billing staff need to ask the right questions at check-in: Is this a new Cigna plan? Was a transition of care request submitted? What's the status? Build these questions into your intake script before October 1, 2025. |
| 5 | Document medical necessity at every visit for transitioning patients. Cigna will use its coverage policy criteria to evaluate whether continued treatment is medically necessary under the new plan. Thin documentation is your fastest path to a claim denial. Make sure your providers are capturing clinical rationale that maps to Cigna's criteria — not just a diagnosis code. |
| 6 | Set a claim denial tracking filter for UM-35-related denials. After October 1, 2025, watch for denial codes tied to transition of care or continuity of care decisions. You want to catch patterns early. A spike in denials from new Cigna enrollees after the effective date is a signal that your intake process isn't catching these cases upstream. |
| 7 | Talk to your compliance officer if you're unsure how this applies to your specialty. Transition of care rules interact with state continuity of care mandates, which vary. If you're in a state with strong continuity protections, there may be additional Cigna obligations that go beyond what UM-35 spells out federally. Don't assume the policy document tells the whole story. |
Cigna Transition of Care Exclusions and Non-Covered Indications
The published UM-35 policy data does not specify explicit exclusions or experimental designations. However, the structure of the policy — evaluating requests against medical necessity criteria — means that treatments Cigna considers non-covered or experimental under the new plan are unlikely to receive transition of care approval.
This matters in practice. If a patient was receiving a therapy that was covered under their previous plan but falls outside Cigna's coverage policy, the transition of care request process will not override that coverage exclusion. Reimbursement is not guaranteed just because a patient was previously authorized for treatment elsewhere.
If you're seeing transition of care denials tied to specific treatments, escalate those to your billing consultant or compliance officer. There's a meaningful difference between a denial because the request wasn't filed correctly and a denial because Cigna's coverage policy doesn't include the service.
Coverage Indications at a Glance
The UM-35 policy data does not list specific indication-level coverage criteria. The policy establishes a process — not a covered/not-covered list by condition or service. Coverage decisions under this policy depend on the specific treatment being requested and whether it meets Cigna's medical necessity standards for that service.
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Ongoing treatment for new Cigna enrollee mid-course | Evaluated case by case | Not specified in UM-35 | Medical necessity review required; prior auth may be needed |
| Continuity with out-of-network provider | Evaluated case by case | Not specified in UM-35 | Transition period may be granted; reimbursement rates vary |
| Treatment covered under prior plan but not Cigna plan | Likely not covered | Not specified in UM-35 | Transition approval does not override Cigna coverage exclusions |
| 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 UM-35
The published UM-35 policy data does not list specific CPT, HCPCS, or ICD-10 codes. This is a process policy, not a procedure-specific coverage policy. It governs how Cigna handles the request workflow, not which specific codes trigger transition of care review.
That said, transition of care billing touches every code category. Any CPT or HCPCS code billed during an active transition period falls under this policy's framework. Medical necessity and prior authorization rules for the specific service still apply — UM-35 governs the door, not what's on the other side of it.
What this means for coding: Don't expect a code list from UM-35. Instead, cross-reference the specific Cigna coverage policy for each service your transitioning patient is receiving. If a patient mid-chemotherapy joins a Cigna plan, you're dealing with both UM-35 (for the transition request process) and Cigna's oncology coverage policies (for whether that specific regimen is covered).
If you're submitting transition of care billing for services where you're uncertain whether a code is covered under the new Cigna plan, verify against the relevant Cigna coverage policy before submitting. A claim denial after the effective date is harder to recover than a pre-submission coverage check.
Why UM-35 Matters Beyond the Policy Document
The modification to UM-35 isn't dramatic on its surface. Cigna says it's establishing a "consistent process." But in billing terms, "consistent process" means Cigna is standardizing how it evaluates these requests — which means your team needs to be consistent too.
Inconsistent documentation, missed prior authorization requests, and outdated intake workflows are the three reasons transition of care claims fail. The UM-35 update gives Cigna a cleaner framework to deny requests that don't fit the process. Your job is to make sure your requests do fit.
The effective date of October 1, 2025 lands at the start of Q4 — right when many patients are approaching end-of-year benefit changes and potential plan switches. Plan for a higher volume of new Cigna enrollees in Q4, and make sure your team is ready.
