Behavioral health gaps in Medicare Advantage: what payers gain by closing them
Key takeaways
- Behavioral health gaps in Medicare Advantage usually start in four places: benefit design, network adequacy, prior authorization, and member cost-sharing.
- Closing those gaps can improve Star Ratings, lower total cost of care, strengthen member retention, and help your plan stand out from competitors.
- Your team can act through network expansion, simpler authorization, thoughtful cost-sharing design, and digital care partners that widen access for your members.
What is an unaddressed behavioral health gap costing your Medicare Advantage plan? According to KFF, 35.2 million Medicare beneficiaries, or 55% of those eligible, are enrolled in Medicare Advantage in 2026. Behavioral health gaps in Medicare Advantage can affect Star Ratings, total cost of care, and member retention across that large population. When members cannot find a provider, wait too long for an approval, or face high copays, your plan feels the effects in its quality scores and enrollment numbers. This article explains where gaps form in benefit design, network adequacy, authorization, and cost-sharing. It shows what your plan gains by closing each one and what to do next.
What behavioral health coverage must your Medicare Advantage plan include?
Your Medicare Advantage plan must cover the mental health and substance use disorder services included in Original Medicare. Knowing that baseline helps your team find where Medicare Advantage behavioral health access falls short of member needs and competitor offers.
The core services are:
- Outpatient therapy and counseling visits
- Psychiatric evaluation and medication management
- Inpatient psychiatric care
- Substance use disorder treatment
Federal mental health parity law (MHPAEA) does not directly apply to Medicare Advantage. Medicare program rules set the standards instead, so your compliance team should confirm current requirements. Plans then manage this coverage with three tools, and each one is a point where gaps can form:
- Networks decide which providers members can see and how quickly.
- Prior authorization decides which services need approval before care starts.
- Supplemental benefits add services or lower costs beyond the Original Medicare baseline.
Original Medicare lets members see any participating provider, so these tools give your plan more control and more responsibility for access.
Which behavioral health gaps in Medicare Advantage cost plans the most?
The costliest behavioral health gaps sit in benefits, networks, authorization, and cost-sharing. The table shows how each one affects your plan and what closing it returns.
Supplemental benefits deserve a closer look because they vary widely from one plan to another. Some behavioral health services may be limited or excluded, so start with the gaps that most affect a member's ability to begin and stay in care, such as extra therapy visits or lower copays. Targeted additions give your plan a clear edge when members compare options.
How do network adequacy shortfalls affect your compliance risk and member access?
Network adequacy standards set how many behavioral health providers your plan needs and how quickly members should be able to reach them. According to KFF, about 60% of Medicare Advantage enrollees had no coverage for mental health and substance use disorder services from out-of-network providers. That makes your in-network roster the main route to care. Expanding in-network provider access can shorten waits, lower compliance risk, and improve mental health access for Medicare Advantage members.
"Members that have to wait weeks for a behavioral health appointment may experience an increase or worsening in symptoms and if on the fence about having the appointment may be more likely to cancel the appointment altogether."

What do Medicare Advantage payers gain by adding or expanding behavioral health coverage?
Closing behavioral health gaps pays back across several plan measures. These are the three benefits that make up the business case for your team:
- Stronger Star Ratings: Behavioral health access and outcomes connect to Star Ratings through member survey results and quality measures. When members reach care sooner, they report better experiences, which gives your plan stronger results to show.
- Lower total cost of care: According to AARP, nearly one in three people with traditional Medicare, almost 10 million, were diagnosed with or reported symptoms of depression, anxiety, or both in 2021 to 2022. Delayed care can surface later as avoidable medical use, so timely access helps meet needs earlier.
- Better retention and differentiation: Members who can find timely behavioral health care have more reason to stay with their plan. Stronger supplemental benefits also give your sales teams a clear point of difference in enrollment season.

How can simplifying behavioral health prior authorization improve Star Ratings and member retention?
Prior authorization is one of the most direct levers your plan controls over access. According to KFF, 98% of Medicare Advantage enrollees were in plans that required prior authorization for some mental health and substance use disorder services. Under the Centers for Medicare and Medicaid Services (CMS) interoperability and prior authorization final rule (CMS-0057-F), Medicare Advantage organizations must decide expedited requests within 72 hours and standard requests within seven calendar days starting January 1, 2026. Drugs are excluded. Plans commonly review higher-intensity services.
The table shows where reviews appear and what a simpler process returns.
How do authorization delays affect treatment continuity and your total cost of care?
Delays can interrupt therapeutic relationships and slow progress, which raises compliance exposure and downstream costs for your plan. Members who wait on an approval may drift away from care, and restarting takes more effort than continuing. Faster decisions help members return to care and keep momentum, which supports Star Ratings and retention.
"If a member has a gap in care, having a treatment plan in place which includes coping tools and a plan to return to treatment can be beneficial."
-Laura Magnuson, MA, MS, LAMFT, VP of Clinical Engagement
How can optimizing cost-sharing design improve behavioral health access and retention?
Cost-sharing is a plan design choice that shapes whether members start and stay in treatment. According to AARP, Medicare beneficiaries with depression or anxiety were more than twice as likely to report cost-related problems getting care as those without these conditions, at 14% versus 6%.
The table shows where your plan can redesign cost-sharing for the greatest return.
Annual out-of-pocket maximums cap what members pay in a year, but members with chronic mental health needs can reach that cap quickly. Review whether your limits protect members who need frequent or intensive care, and compare your cost-sharing with competing plans and Original Medicare.
Where can Medicare Advantage plans lead traditional Medicare on behavioral health access?
Your plan can lead traditional Medicare on Medicare Advantage behavioral health access when it pairs managed care tools with faster access to providers. Two areas show the most room to build a retention advantage:
- Utilization patterns: Comparing how often members use behavioral health services points to access barriers and untapped demand. Low use can signal that members struggle to find or afford care.
- Provider availability and wait times: Medicare Advantage networks can be narrower than the broad provider access in traditional Medicare, so wait times and geography matter more. Mapping gaps by county helps your team decide where to add providers first.
What do recent policy changes mean for your Medicare Advantage behavioral health coverage?
CMS has raised expectations for behavioral health in Medicare Advantage, and acting early helps your plan avoid compliance risk and stay ahead of competitors. The contract year 2024 final rule includes three changes your network team should know:
- Clinical psychologists and licensed clinical social workers were added as network specialty types eligible for the telehealth credit.
- Appointment wait time standards now apply to behavioral health.
- Plans must notify enrollees when a behavioral health provider leaves the network midyear.
Federal parity law still does not directly apply to Medicare Advantage. CMS requirements nonetheless move plans toward parity, for example, through care coordination programs that include behavioral health.
How can your Medicare Advantage plan close behavioral health coverage gaps?
Medicare Advantage plans can close behavioral health coverage gaps with a few targeted changes that improve access while supporting Star Ratings, total cost of care, and member retention. Start by evaluating the plan design as a whole, looking at network adequacy, authorization requirements, and cost-sharing alongside utilization, wait times, and denial data to identify where coverage remains thin.
Simplifying the appeals process can then help members and providers resolve denials faster by reducing unnecessary documentation hurdles and clarifying next steps, which can also support stronger member satisfaction. Finally, adding access partners such as virtual care networks, technology partners, primary care-based collaborative care, and community navigation services can expand behavioral health access for Medicare Advantage members. The latest trends in behavioral health technology offer examples of how these partners can connect with existing health plan networks.
