Ambulatory Surgery Centers (ASCs) are positioned for continued growth in 2026, fueled by demand for cost-effective outpatient procedures. But growth brings complexity — and billing remains one of the most vulnerable areas in ASC operations. From payer pushback to compliance risks, many centers are navigating the same bottlenecks month after month, often without realizing the cumulative revenue impact.
If you’re responsible for an ASC’s financial health, it’s time to take a hard look at where your billing may be falling short. These are the 10 most pressing billing challenges ASCs face in 2026 — and the proven ways to fix them before they affect your margins or compliance standing.
Incomplete or Delayed Documentation
The challenge: Timely and accurate documentation remains a weak point in many ASCs. Surgeons may delay entering operative notes, or key details get missed in the rush between cases. The result? Denials, underpayments, and days (or weeks) added to the revenue cycle.
The fix: Create documentation deadlines tied to workflow — not calendar days. Same-day documentation policies should be the standard, not the exception. Integration between your EMR and billing platform can also reduce manual delays and reduce missed charges.
Rising Denial Rates from Payers
The challenge: Denials aren’t just rising — they’re becoming harder to overturn. In 2026, payers are tightening scrutiny on coding specificity, prior authorizations, and even the definition of “medical necessity.” ASCs that lack robust tracking systems often miss patterns until thousands have already been lost.
The fix: Use denial data strategically. Track denials by reason code and payer, then build proactive flags into your billing workflow. If you outsource billing, make sure your partner provides regular denial analysis and can handle appeals without delay.
Coding Errors from Procedural Complexity
The challenge: As ASC procedures become more advanced, coding gets more nuanced. Even experienced coders can struggle to apply CPT and modifier rules correctly — especially when procedure notes are unclear.
The fix: Ensure coders are ASC-specialized and AAPC-certified. At MHS, our coders receive ongoing education specific to ASC trends and payer changes. Monthly audits can catch documentation or coding issues before they become systemic revenue drains.
Bundled Payments and Underpaid Claims
The challenge: Bundled reimbursement models offer predictability, but they also create confusion. Many ASCs unknowingly underbill because bundled rates are misinterpreted or applied incorrectly.
The fix: Collaborate with payers to define what’s included in the bundle. Billing staff must be trained on ASC-specific contracts and allowed time to review carrier rules before coding begins. A centralized billing partner can help reduce errors by standardizing payer logic across cases.
Credentialing Gaps That Delay Billing
The challenge: Provider credentialing is often treated as a back-office task, but when it’s mishandled, the impact hits the front lines of revenue. Without current payer enrollment, claims are unbillable — or worse, denied after months of delay.
The fix: Build a credentialing calendar with automated alerts for re-credentialing deadlines, expirations, and plan renewals. Outsourcing credentialing to a partner like MHS ensures all providers are actively enrolled and ready to bill, minimizing gaps.
Lack of Visibility Into Financial Performance
The challenge: Many ASC leaders only see top-level revenue figures — with little insight into denial rates, charge lag, or aging balances. Without clear data, it’s difficult to identify bottlenecks or measure vendor performance.
The fix: Use real-time dashboards that display aging, collections, denials, and payer trends in one view. MHS clients gain access to detailed RCM analytics as part of our standard service, providing the transparency ASC leaders need to act decisively.
Compliance Risks With Surprise Billing Laws
The challenge: Enforcement of the No Surprises Act is growing stricter, and ASCs must comply with both federal and evolving state-level rules. Noncompliance can trigger fines, payment holds, or legal disputes with patients.
The fix: Review your patient intake and financial consent process. Are patients being notified of potential out-of-network charges correctly? Are forms being retained and timestamped? Work with a billing partner who understands the evolving legal landscape and keeps your workflows compliant.
Inconsistent Patient Collections
The challenge: With the rise in high-deductible plans, patient responsibility is growing — but many ASCs still lack a system for pre-procedure collections. This creates uncomfortable billing surprises post-op and lowers collection rates overall.
The fix: Offer pre-service estimates, train front-desk staff to explain financial responsibility clearly, and set up automated follow-ups post-procedure. Digital tools like text-to-pay and payment plans increase conversion and reduce bad debt.
Staffing Turnover That Disrupts Revenue Flow
The challenge: Billing teams are vulnerable to turnover, and when experienced staff leave, so does institutional knowledge. New hires may take months to get up to speed, leaving cash flow lagging.
The fix: Protect revenue by partnering with a billing team that brings built-in continuity. At MHS, our clients never face downtime due to internal turnover — our systems and support staff ensure billing keeps moving, regardless of personnel changes.
Vendor Fragmentation
The challenge: Using separate vendors for billing, credentialing, analytics, and compliance creates confusion, delays, and gaps in accountability. Information gets lost between handoffs, and no one is fully responsible for results.
The fix: Consolidate your billing, credentialing, and analytics under one experienced partner. This streamlines communication, improves accountability, and delivers better outcomes — financially and operationally.
Final Thoughts
The ASC landscape in 2026 demands precision, proactivity, and smarter infrastructure around billing. Every missed charge, delayed credential, or overlooked denial has a direct impact on your bottom line. But with the right systems and support, these challenges are fully solvable.
