UnitedHealthcare and Humana Medicare Advantage Discontinuation: What Providers Need to Know for 2027
The Medicare Advantage landscape is changing ahead of 2027, and healthcare providers need to prepare for the potential impact on patient coverage, insurance eligibility, claim submission, and reimbursement. UnitedHealthcare and Humana have announced plans to discontinue certain Medicare Advantage offerings, affecting nearly one million members combined, according to recent reporting.
These changes do not mean that all UnitedHealthcare or Humana Medicare Advantage plans are ending. Instead, specific plans and service areas are being affected as insurers adjust their offerings for the upcoming plan year.
For medical practices, home health agencies, specialty clinics, and other healthcare organizations, the key concern is how these changes may affect existing patients and billing operations. Outdated insurance information, unverified coverage, and changes in payer participation can create avoidable administrative work and potential claim delays.
In this guide, we explain the Medicare Advantage discontinuation involving UnitedHealthcare and Humana, what the 2027 changes mean for healthcare providers, and how practices can prepare their revenue cycle management processes.
What Is Happening With UnitedHealthcare and Humana Medicare Advantage Plans?
UnitedHealthcare and Humana are making changes to selected Medicare Advantage plans for the 2027 plan year. The announcements come as insurers reassess their plan offerings, provider networks, and financial performance.
According to recent reporting, approximately 390,000 UnitedHealthcare members and 600,000 Humana members are affected by planned plan discontinuations. The specific plans and locations affected vary, and providers should not assume that every member of either insurer will lose their current coverage.
UnitedHealthcare confirmed that certain Medicare Advantage plans and service areas will change effective January 1, 2027. Humana has also announced targeted plan exits affecting a portion of its Medicare Advantage membership.
Healthcare providers should review the official announcements and payer communications to determine which plans are affected in their service areas.
Why Are Medicare Advantage Plans Being Discontinued?
Health insurers regularly evaluate their Medicare Advantage offerings based on medical costs, utilization trends, reimbursement, network arrangements, and overall financial performance.
Recent industry reporting has linked the 2027 changes to rising healthcare costs, increased utilization, and insurers’ efforts to focus on selected markets and plan types.
These adjustments can involve discontinuing specific plans, reducing coverage in certain counties, or changing the mix of health maintenance organization (HMO) and preferred provider organization (PPO) options.
The distinction matters. A discontinued plan does not necessarily mean an insurer is leaving an entire state or ending all Medicare Advantage coverage. Other plans may remain available in the same location.
For healthcare organizations, the practical priority is identifying which patients may be affected and verifying their coverage before providing and billing for services.
How Could Medicare Advantage Discontinuation Affect Healthcare Providers?
Changes to Medicare Advantage plans can create operational challenges for healthcare providers, particularly when patients must select new coverage or transition to a different insurance arrangement.
The following areas deserve particular attention.
1. Patient Eligibility and Insurance Verification
One of the most important steps in medical billing is verifying that a patient’s insurance information is accurate and that the intended services are covered under the patient’s current plan.
When a Medicare Advantage plan is discontinued, a patient may enroll in another Medicare Advantage plan or transition to Original Medicare, depending on their circumstances and enrollment choices.
A patient’s previous insurance card or payer information may no longer reflect their coverage after the change takes effect.
Healthcare practices should review upcoming appointments, identify potentially affected patients, and verify their current coverage through appropriate payer eligibility systems.
Insurance verification should include the effective dates of coverage, payer identification, applicable benefits, and any relevant authorization requirements.
2. Changes in Provider Network Participation
A provider’s participation status may differ between insurance plans offered by the same company.
For example, being in-network with one UnitedHealthcare Medicare Advantage plan does not automatically establish in-network participation with every other UnitedHealthcare plan.
Similarly, a patient moving from one Humana plan to another may have different network arrangements or benefit requirements.
Before scheduling non-emergency services under a new plan, providers should confirm their participation status and review the applicable network requirements.
Accurate network verification helps practices communicate potential out-of-pocket costs and reduce administrative issues related to plan participation.
3. Prior Authorization and Benefit Requirements
Medicare Advantage plans can have different prior authorization processes, referral requirements, and covered benefits.
When a patient changes plans, an authorization obtained under the previous plan should not automatically be assumed to apply to the new coverage.
Practices should review authorization requirements for the new plan, confirm whether existing approvals remain valid, and document any necessary follow-up with the payer.
This is especially important for services that involve ongoing treatment, specialist visits, diagnostic procedures, rehabilitation, or home healthcare.
4. Claim Rejections and Reimbursement Delays
Incorrect payer information, inactive coverage, and billing under an outdated member ID can result in claim rejections or processing delays.
These problems can increase the time billing teams spend correcting submissions, contacting payers, and following up on unpaid claims.
However, not every claim issue following an insurance change is caused by the discontinuation itself. Claims can also be affected by authorization gaps, coding errors, eligibility discrepancies, or differences in plan benefits.
A structured eligibility verification and claim review process helps providers identify these issues earlier and resolve them efficiently.
What Should Medical Practices Do Before January 2027?
Healthcare providers can reduce avoidable billing disruptions by preparing for the upcoming plan year before the changes take effect.
The following checklist can help practices organize their preparation.
Step 1: Identify Potentially Affected Patients
Review your patient records for individuals currently enrolled in UnitedHealthcare or Humana Medicare Advantage plans.
Use official payer notices and plan information to determine whether a patient’s specific plan is affected. Do not assume that all members of either insurer will experience a change.
Create a process for flagging records that require updated insurance information.
Step 2: Reverify Insurance Eligibility
As patients approach upcoming appointments, confirm their active coverage using the appropriate payer eligibility tools.
Verify the effective date, member identification details, plan type, and relevant benefits. Update patient records when new information is confirmed.
Do not rely solely on an old insurance card or a previous eligibility check when a plan change may have occurred.
Step 3: Confirm Network Participation
If a patient enrolls in a different Medicare Advantage plan, verify whether the practice participates in that specific plan.
Review applicable network agreements and confirm the payer’s requirements before representing a service as in-network.
This step is particularly important for specialty practices and providers who serve patients across multiple insurance networks.
Step 4: Review Prior Authorization Requirements
Identify patients receiving services that require prior authorization or referrals.
Check whether the new plan requires a new authorization, additional documentation, or a revised approval process. Track pending authorizations so that necessary follow-up is not overlooked.
For ongoing treatment, communicate with the payer and patient as appropriate to minimize preventable administrative interruptions.
Step 5: Update Billing and Practice Management Systems
Ensure that billing staff use the correct payer information, member IDs, plan details, and effective dates when submitting claims.
Establish a consistent process for updating insurance records and communicating coverage changes between front-desk staff, clinical teams, and billing personnel.
Accurate records help reduce errors caused by outdated information.
Step 6: Monitor Claims and Accounts Receivable
Review claim rejections, denials, and unpaid accounts associated with affected patients.
Identify recurring issues such as eligibility mismatches, incorrect payer selection, missing authorizations, and incomplete documentation.
Track the reason for each issue and follow the appropriate correction or appeal process when applicable.
Regular accounts receivable reviews help billing teams identify unresolved claims before they become prolonged reimbursement problems.
How Medicare Advantage Changes Can Affect Revenue Cycle Management
Revenue cycle management (RCM) includes the administrative and financial processes involved in registering patients, verifying insurance, submitting claims, collecting payments, and managing outstanding balances.
Insurance plan changes can place additional pressure on these workflows when patient records, payer requirements, and coverage information are not updated promptly.
Eligibility Verification and Front-End Accuracy
Accurate eligibility verification helps establish whether a patient has active coverage for the services being provided.
When billing teams identify coverage changes early, they can update records, review benefit requirements, and address discrepancies before claim submission.
This supports cleaner billing workflows and can reduce avoidable administrative rework.
Claims Management and Denial Prevention
A well-organized claims management process helps billing teams identify and correct issues that may delay reimbursement.
Practices should monitor payer responses, review rejection codes, correct inaccurate information, and submit corrected claims when appropriate.
Denials should also be categorized by cause so that recurring problems can be addressed through workflow improvements rather than repeated manual corrections.
Accounts Receivable Follow-Up
When claims remain unpaid, timely follow-up helps determine whether the issue involves eligibility, authorization, documentation, processing delays, or another payer requirement.
A consistent accounts receivable workflow can help practices prioritize outstanding claims, track payer responses, and maintain visibility into reimbursement performance.

What Patients and Providers Should Know About the 2027 Transition
Medicare Advantage plan changes can affect patients differently depending on their location, current plan, enrollment decisions, and available alternatives.
The Medicare Open Enrollment Period runs from October 15 through December 7, 2026. During this period, eligible beneficiaries can review their coverage options and make permitted changes for the 2027 plan year.
Affected members should read their plan’s official nonrenewal notice and review the enrollment options and effective dates that apply to their situation.
Healthcare providers should avoid assuming that a patient will automatically enroll in a replacement Medicare Advantage plan. Depending on the circumstances and applicable rules, coverage may change in other ways.
Practices should also avoid assuming that a patient’s benefits, network participation, or authorization requirements will remain identical after a plan change.
For reliable information, providers and patients should consult the insurer’s official notices and the Centers for Medicare & Medicaid Services (CMS).
