How to Manage Silent Ophthalmology Billing Denials in 2026

Ophthalmology is undoubtedly considered one of the most intricate specialties to manage. And this year, as we step into 2026, the complexity hasn’t decreased further; rather, it has simply evolved. In fact, for many ophthalmology clinics, the difference between a thriving one and a struggling one with cash flow isn’t the number of patients in the waiting room; it’s the precision of the coding. Also, not to forget how efficient its back ophthalmology billing office is can also make a huge difference. Thus, ophthalmology clinics are looking for a more convenient solution, as with the shifting CMS compliance regulations, with medical and vision insurance requirements; a good enough approach to billing is no longer sustainable.

Why Ophthalmology Clinics Are Experiencing a Decline in Net Collection Rates

With the recent use of AI and technological advancements, automated underpayment is one of the most significant trends and also the primary reason for maximum denials. Today, unlike traditional denials in which a claim is sent back for correction, many payers now use AI-driven algorithms to process claims, which often lack clarity. While these systems often apply internal efficiency edits that downcode E/M levels or bundle procedures without a formal rejection, it tend to create a lot of confusion.

So, if your billing team isn’t performing a rigorous line-item contract audit, these small discrepancies, which often range from $15 to $50 per claim, go unnoticed. And over a year for a mid-sized practice, this can result in a six-figure loss. This is why human intervention in managing ophthalmology Billing is quite crucial.

Deciphering the 2026 Coding Maze of Eye Codes vs. E/M

The perennial debate in eye care billing remains for many ophthalmologists whether to use the 920xx Eye Codes or the 992xx E/M Codes. While in 2026, the answer is quite simple and increasingly data-dependent.

92014 (Comprehensive Eye Exam): This code is used when providers seek a more stable reimbursement for routine medical checks.

99214 (Level 4 Office Visit): Whereas in 2026, this code here requires a higher level of medical decision-making (MDM). A complex case involving co-morbidities or high-risk medication management often yields a higher return than a standard eye code.

While the other trick is ensuring your ophthalmology medical billing software, like AdvancedMD, CureMD and your billers, are synced, it is important to note that wrong code here not only risks underpayment but also flags your practice for outlier behavior in payer audits.

Best Practices for Maximizing Ophthalmology billing Reimbursement

To stay ahead, Ophthalmology practices need to adopt a proactive rather than reactive stance or even expert help from SunKnowledge can make a huge difference. As we not only undertsand the billing complications but also the payer’s requirements. In fact, our core pillars of a modern, efficient revenue cycle, starting from:

1. Real-Time Eligibility Verification:

The front-end of the billing cycle is where most errors are born. By implementing real-time verification 48 to 72 hours before the appointment, you eliminate the Coordination of Benefits (COB) errors that plague ophthalmology. This is especially critical for patients who carry both a commercial vision plan and a Medicare Advantage medical plan.

2. Mastering Laterality and Modifier -25

Laterality (RT/LT) remains a top audit target, and in 2026, for a seamless billing structure, you need to code accurately with the right modifier to get paid timely. For example, H40.1121 for primary open-angle glaucoma, left eye matches the procedure modifier. Furthermore, the use of Modifier -25 for same-day injections should be carefully considered. Your documentation must clearly show that the E/M service was above and beyond the typical pre-procedure workup.

3. Work on Ophthalmology Denials Management Bottleneck

Many practices let difficult denials sit in the AR (Accounts Receivable) for 60 + days. And in 2026, as the timely filing windows are shrinking, one needs to further ensure an effective denials management strategy by identifying the root cause, whether it is a credentialing issue or a coding error. Categorize denials by payer to spot bad faith processing trends and even aggressively ensure daily follow-ups so claims don’t hit the 90-day dead zone. In fact, for decades, SunKnowledge has helped many ophthalmology clinics with a seamless billing process with tailored-customized billing solutions.
