If your net collection ratio (NCR) is under 95%, then yes, you are below the 2026 benchmark, and the gap is costing you real money. The commonly cited MGMA-aligned target is 95% or higher, and top-performing groups reach 96% to 99%. Strong Optometry Billing Services close that gap by getting three things right: the medical-versus-vision split, OCT edit rules, and payer frequency limits. This guide shows how to check your number, where eye care groups lose points, and what to fix before the October 1 code update.
What the 2026 NCR Benchmark Really Means for an Eye Care Group
NCR tells you how much of the money you were allowed to collect actually landed in your bank. The formula is simple: payments divided by charges minus contractual write-offs, multiplied by 100. Track it on a rolling 12-month basis so seasonal dips do not fool you.
Here is why it matters. On $5 million in net charges, each NCR point is worth $50,000. A group sitting at 92% instead of 96% leaves about $200,000 uncollected every year, with no extra patients needed to win it back.
| NCR range | What it usually signals | Where to look first |
| 96% to 99% | Clean front end, active follow-up | Protect it by watching payer contract changes |
| 93% to 95% | Solid, but quietly leaking | Underpayments and aging patient balances |
| 90% to 92% | Process gaps are stacking up | Medical vs vision routing, unworked denials |
| Below 90% | Systemic leakage | Full billing audit, eligibility and coding review |
Ranges are industry-reported and MGMA-aligned, not government-verified. Your payer mix will move them.
Why Optometry Billing Services Work Differently From General Medical Billing
Optometry runs two insurance systems at the same time. Vision plans such as VSP and EyeMed typically pay around $45 to $70 for a routine exam and limit how often you can bill it. Medical insurance typically pays around $120 to $180 for a medically driven visit, but it demands a precise ICD-10 diagnosis (industry-reported ranges, and they vary by payer and region).
Most general medical billing services build one workflow for one kind of payer. A biller who treats every claim as medical, or every claim as vision, will lose NCR either way. Specialized Optometry Billing Services are built around the fork in the road.
The Same-Visit Split Behind Most NCR Losses
Picture a patient who books “new glasses.” During the exam, the doctor finds elevated eye pressure or the patient mentions new floaters. That visit is no longer routine. The diagnosis should move from a routine exam code to the actual condition, and the exam plus any testing belongs on the medical claim.
When the patient has both coverages, you can bill both on the same date. The comprehensive exam (92004 or 92014) and testing go to medical insurance. The refraction (92015) goes to the vision plan or the patient, since Medicare does not cover it. Medically necessary contact lenses, such as for keratoconus or aphakia, also belong on the medical side.
Try this illustrative model with your own numbers. A four-provider group sees 30 patients a day, and 20% of those visits are medically driven but billed to vision at $55 instead of medical at $150. That is six visits a day and a $95 gap each, or about $142,500 a year. Nobody denied anything. The money simply never got asked for.
Rejections Never Show Up in Your Denial Report
Here is a gap most dashboards hide. A denial comes from a payer. A rejection is stopped at the clearinghouse and never reaches the payer at all. Because it is not a denial, it will not appear in your denial report.
A classic example is billing 92013, which is not a valid code. Eye exam codes are 92002 and 92004 for new patients, 92012 and 92014 for established patients. A claim with the wrong code just sits in a rejection queue while its timely filing clock keeps ticking. Another common slip is adding G2211 to an eye code. That add-on needs a qualifying E/M base code, so verify the base code first.
The fix is a boring one. Work the rejection log every day, not just the denial report. A claim that never reached a payer cannot be appealed.
OCT, Fundus Photos and the Edits That Cancel Them Out
Testing is where clean exams turn into denials. CMS guidance generally treats scanning imaging (92133 or 92134) and fundus photography (92250) as alternative ways of looking at the same thing, so billing both on the same day invites an edit. The two OCT codes also cannot be billed together for the same eye on the same day. You can review the current rules on the CMS NCCI edits page.
Frequency limits are the second trap. If a patient had an OCT six months ago, your note needs to say why another one is medically necessary now. Traditional Medicare usually does not require prior authorization for diagnostic testing, but many Medicare Advantage plans do. Keep a plan-by-plan authorization list, because one unauthorized OCT can cost more to appeal than the test pays.
Good Optometry Coding Services review the chart against these edits before the claim goes out, not after the denial comes back.
Your Q4 2026 Checklist: Ten Days to the October 1 Update
Today is September 21, so the October 1 code refresh is close. The FY2027 ICD-10-CM update takes effect that day, and the quarterly NCCI edit refresh often lands then too. Ask your team or vendor whether your diagnosis lists and claim scrubber rules have been updated. Outdated diagnosis codes are among the easiest denials to prevent.
Medicare Advantage open enrollment runs October 15 to December 7, which means new plans and changed eligibility for many patients in January. Re-verify coverage at check-in, and reset your patient balance workflow before the year-end deductible reset hits.
Optometry Billing Services vs. In-House Billing: Who Should Own Your NCR?
In-house billing works when one person truly understands both vision and medical workflows. It breaks when that person leaves, and the knowledge leaves with them. Outsourcing works when the partner brings depth you cannot hire easily.
If you are comparing vendors, ask these questions:
- How do you route visits when a patient has both medical and vision coverage?
- Do you work the clearinghouse rejection log daily?
- Will you report NCR by payer on a rolling 12-month basis?
- Do your coders review 92xxx eye codes against E/M codes before submission?
Look for RCM services that pair coding and billing under one roof. Optometry Billing and Coding Services from one team remove the handoff where documentation gaps turn into denials. Medical billing services that only offer generic workflows will struggle with the dual-payer reality. Real people who know eye care, supported by good technology, beat automation alone.
Blog Summary
Your NCR should be 95% or higher, and 96% to 99% is where top-performing groups sit. In optometry, the biggest leaks come from medical visits billed to vision plans, rejections that never appear in denial reports, OCT and fundus edit conflicts, and missing frequency documentation. On $5 million in net charges, every point is worth $50,000. With the October 1 update ten days away, this is the right week to audit your numbers.

FAQs
A good NCR is 95% or higher. Top-performing eye care groups reach 96% to 99%. These ranges are industry-reported and vary by payer mix.
Divide total payments by charges minus contractual adjustments, then multiply by 100. Use a rolling 12-month window for a stable number.
Yes, when the patient has both coverages and the services fit each plan. The medical exam and testing go to medical insurance, and the refraction goes to the vision plan.
Common causes are billing OCT and fundus photography together, exceeding frequency limits, missing medical necessity notes, and skipped Medicare Advantage authorizations.
They manage two payer systems at once, apply eye-specific coding rules, and track vision plan limits alongside medical edits. General billing teams rarely build for both.
