ACA enhanced subsidies may expire at the end of December. And that uncertainty is already shaping patient decisions this open enrollment season. Many will switch plans, some may drop coverage, and medical practices need to prepare for the ripple effects now!

Key Takeaways

• Open enrollment is more unpredictable this year because enhanced ACA subsidies may expire. And that uncertainty is already shaping how patients choose coverage and how practices plan for 2026.
• Medical practices should expect more insurance churn, more eligibility checks, and tighter reimbursement patterns as patients shift to cheaper or narrow-network plans.
• A connected platform that brings EHR, practice management, and RCM together can give practices the operational stability they need at a time when policy (and patient behavior) is uncertain.

Open enrollment is here again. But this season comes with a question medical practices can’t ignore: What happens if ACA enhanced subsidies aren’t renewed for 2026?

For years, these subsidies have helped millions of US citizens afford coverage and provided medical practices with a steadier payer mix. The uninsured rate has nearly been cut in half since 2013. Now that the government hasn’t agreed on an extension, patients are unsure what their premiums will look like next year. And that uncertainty is showing up in exam rooms, at front desks, and inside billing workflows.

Many patients are hesitating to choose a plan. Some are shifting to lower-cost, narrow-network options. Others are considering dropping coverage altogether. All of this puts medical practices in a difficult position: more insurance questions, more eligibility checks, and less predictable reimbursement heading into 2026.

Medical practices need clarity to plan for the year ahead, but they also need systems that can absorb this level of instability without slowing down operations or cash flow. This blog explores how these policy shifts may affect your patients, your workload, and your revenue, and the steps you can take to stay ready.

ACA and Enhanced Subsidies — A Quick Refresher

Before we talk about what’s happening this enrollment season, it’s worth grounding ourselves in why the ACA still shapes practice operations every single day.

For many clinics, the ACA stabilized revenue, reduced bad debt, and lowered the number of uninsured patients coming through the door. Understanding how enhanced subsidies changed the landscape helps explain why their uncertain future is causing anxiety across medical practices.

● How the ACA Changed the Financial Landscape for Medical Practices

The Affordable Care Act wasn’t simply a policy shift. It marked a turning point for provider finances. When Marketplace coverage launched in 2014, more patients gained insurance, and practices saw fewer unpaid visits and more predictable cash flow.

A few numbers show the scale of this shift:

• The uninsured population dropped from roughly 45.2 million in 2013 to 26.4 million by 2022.
• The national uninsured rate fell from 14.4% to 7.9% over the same period.

For medical practices, that meant:

• More insured patients scheduling visits
• Fewer self-pay balances turning into write-offs
• A more reliable reimbursement environment

Every one of those improvements tied back to one thing: affordability. And affordability hinges heavily on subsidies.

● The Evolution of Enhanced Subsidies (2021–2025)

Enhanced subsidies were introduced during the pandemic. But they ended up reshaping Marketplace affordability more dramatically than anyone expected.

2021 — ARPA Expands Subsidies

• The American Rescue Plan Act (ARPA) removed the “400% FPL cliff.”
• Premiums dropped significantly for millions of Americans.
• The expansion cost was roughly $34 billion across 2021 and 2022.

This meant more patients could afford coverage and choose care sooner rather than delaying it.

2022 — IRA Extends Subsidies Through 2025

• The Inflation Reduction Act (IRA) extended these enhanced subsidies for three more years.
• Practices enjoyed continued stability, with more insured patients and steadier reimbursements.

2025 — And Now, Uncertainty

Here’s where the concern begins:

The government has not yet agreed on an extension beyond December 31, 2025.

If subsidies lapse:

• Marketplace premiums could double for many patients.
• Millions may reconsider coverage altogether.
• Practices may see a shift toward high-deductible or narrow-network plans.

Currently, ACA Marketplace subsidies cost roughly $14 billion per year, according to a KFF report . And making enhanced subsidies permanent is estimated to cost around $350 billion over the next 10 years. That’s a major reason lawmakers are divided.

Why ACA Subsidy Uncertainty Matters to Medical Practices Long Before 2026 Arrives

If enhanced subsidies end after December 31, 2025, the financial ripple will reach medical practices during the open enrollment period (ending on January 15, 2026) and long before the deadline arrives.

Patients will make coverage decisions during this open enrollment with next year’s affordability in mind, and those decisions shape your payer mix, your schedule, and your revenue cycle. Here’s what practices should expect if subsidies are not extended.

1. Premiums Rise and Patients Reconsider Coverage

Enhanced subsidies have kept Marketplace premiums significantly lower for millions of Americans. Without them, many households could see premiums double, especially for silver-tier plans. For patients already balancing deductibles and cost-sharing, that increase may push them toward:

• Cheaper plans with narrow networks
• High-deductible health plans
• Downgrading coverage
• Or opting out entirely

And for medical practices, this means more uncertainty at the front desk and a higher risk of coverage gaps mid-year.

2. More Uninsured Patients and Higher Out-of-Pocket Balances

In case ACA enhanced subsidies lapse, analysts expect coverage losses. Even a slight increase in the number of uninsured patients affects medical practices directly. Expect:

• More self-pay visits
• Higher likelihood of delayed care
• More difficulty collecting balances
• Increased uncompensated care and write-offs

The progress made since 2013 (when the uninsured rate fell from 14.4% to 7.9%) may begin to diminish. And this will place more financial pressure on independent medical practices.

3. Wider Use of Narrow-Network Plans

With subsidies not in the equation anymore, patients looking for a lower premium will likely migrate to narrow-network plans. For medical practices, that can mean:

• Losing in-network status
• Change in referral patterns
• Sudden drops in new-patient volume
• More eligibility checks and prior authorizations

And this shift will especially impact specialties, community health centers, and practices serving lower-income populations.

4. More Scheduling Instability and Visit Delays

Coverage uncertainty has always impacted patient behavior. If patients aren’t sure they can afford coverage next year, they may:

• Delay routine visits
• Push off preventive care
• Cancel appointments when premiums rise
• Wait until a visit becomes an absolute necessity

And due to this change in patient behavior, medical practices may see more acute visits, fewer follow-ups, and heavier demand for chronic-care support.

5. Revenue Cycle Volatility Becomes the New Normal

Patients changing plans will directly impact payer mixes for medical practices. A changing payer mix means your RCM processes will be tested. Expect:

• More eligibility-related denials
• Higher patient responsibility amounts
• More variability in reimbursement timelines
• Increased collections workload

Without reliable auto-eligibility verification tools, automated claims workflows, and clear patient communications, medical practices are likely to experience cash-flow disruptions within weeks of the new plan year.

6. Operational Planning for 2026 Becomes Challenging

Even though subsidy decisions rest with lawmakers, the operational impact falls on practices. With no clear policy direction yet, forecasting becomes difficult:

• How many patients will switch plans?
• What will your payer mix look like in Q1 and Q2?
• Will your referral partners remain in-network?
• What does this mean for staffing and scheduling?

There are no clear answers to these questions. But medical practices must be prepared for what 2026 throws their way once the ACA subsidy debate concludes.

Medical Practices Can Prepare for What’s Next With the Right Practice Management System

The government has yet to decide the fate of ACA enhanced subsidies. And the subsidies are likely to expire by the end of December. But the operational risk it creates is predictable: more eligibility questions, more denials, more churn, and more pressure on staff.

A reliable, AI-powered, and integrated EHR, practice management, and revenue cycle management system gives practices the safety net they need heading into 2026. The goal isn’t to “keep up” with what’s about to change. It’s to stay ahead of it.

Below are the core practice management system features that can help medical practices stay steady even when insurance behavior becomes unpredictable.

1. Auto-Eligibility Checks When Coverage Keeps Changing

When patients switch plans (sometimes multiple times during open enrollment), it becomes crucial to run auto-eligibility checks to determine coverage and avoid claim denials.

A modern practice management system helps teams:

• Check coverage instantly
• Identify high deductibles and limited networks early
• Reduce surprises that lead to patient frustration
• Prevent avoidable denials before claims leave the clearinghouse

For practices expecting more churn, this is one of the most effective ways to protect revenue and improve staff efficiency.

2. Automated Claims & Denial Management to Protect Revenue

Billing workload will increase after ACA enhanced subsidies expire. And this will be one of the major reasons for staff burnout and claim denials. More narrow-network plans and higher out-of-pocket totals mean:

• More prior authorizations
• More eligibility-related denials
• More claim edits and resubmissions

Automating your practice can help downsize the impact. An integrated clearinghouse with automatic claim editing tools, batch submission, and smart denial routing helps practices maintain steady cash flow, even when payer rules tighten or patient coverage shifts mid-year.

3. Scheduling Tools That Adapt to Patient Behavior

Open enrollment always brings scheduling instability. Patients delay care, cancel at the last minute, or switch to telehealth to manage costs. When subsidies are uncertain, this behavior becomes even harder to predict. Medical practices need scheduling tools that respond quickly and reduce staff workload.

That’s something a reliable practice management system can help with. What a good scheduling system should offer:

AI Calling Agents: AI calling agents can call patients to confirm appointments, handle cancellations, and reschedule visits without staff intervention. This reduces phone volume and keeps the day's schedule accurate.

A Unified Calendar: Clinics need to view every provider's availability in a single calendar. It becomes easier to fill open slots, avoid double booking, and route patients to the right clinician when insurance plans change.

Automated Reminders: Automated reminders can drastically reduce no-shows. Patients receive texts or calls that help keep them on track. Practices reduce missed appointments and protect revenue.

4. Reporting & Analytics for Better Financial Decisions

Subsidy uncertainty makes forecasting harder. But it doesn’t make it impossible. All medical practices need is visibility into:

• Payer mix trends
• Reimbursement patterns
• Patient responsibility amounts
• Outstanding AR and denial categories

With clear analytics, leaders can model “what if” scenarios, such as higher uninsured rates or narrower networks, and prepare staffing, budgets, and care delivery accordingly. Better data now means fewer surprises next year.

5. Interoperability That Reduces Fragmentation

When patients switch plans, they often switch doctors or healthcare providers. Without interoperability, this leads to fragmented care and delays in treatment plans. An interoperable EHR and practice management system helps practices:

• Retrieve clinical histories when new patients arrive
• Share records with referral partners
• Maintain continuity of care across plan changes
• Reduce duplicate testing and improve documentation accuracy

In a year when many patients may move between plans, an all-in-one EHR and practice management system becomes a critical stability tool.

Stability in an Uncertain Subsidy Future Starts With Your Practice Management Platform

The future of ACA enhanced subsidies remains uncertain. But medical practices can control how prepared they are for the operational ripple effects.

When insurance behavior becomes unpredictable, practices need a single source of truth for coverage, scheduling, documentation, billing, and financial performance. A connected platform that brings together EHR, practice management, and revenue cycle management keeps teams grounded even when payer mixes shift and patient decisions change week to week.

A unified system gives practices the visibility they need to manage eligibility changes, prevent denials, monitor reimbursement trends, and keep patient care on track during enrollment volatility.
