Ophthalmology billing hinges on the 90-day cataract global period, bilateral modifier 50 rules, and anti-VEGF injection J-code capture. Add YAG capsulotomy timing within post-op global and SLT bundling — and general billers miss revenue on every procedure. MedFactor delivers ophthalmology-specific RCM that protects every claim.
From high-volume cataract ambulatory surgery centers to retina practices running anti-VEGF injection suites, we tailor billing to the coding rules of every ophthalmology subspecialty.
Cataract extraction with IOL (66984/66982), 90-day global management, premium IOL upgrades, and refractive laser procedures.
SLT/ALT trabeculoplasty (65855), medication management, and surgical glaucoma procedures with bilateral and global-period accuracy.
Anti-VEGF intravitreal injection (67028), J-code drug billing, waste calculation, and OCT imaging for macular and retinal disease.
Corneal cross-linking, transplants, dry-eye procedures, and external disease management with proper device and supply capture.
Blepharoplasty, ptosis repair, and reconstructive eyelid surgery with cosmetic-vs-reconstructive documentation and prior auth support.
Strabismus surgery, amblyopia management, and age-based E/M with proper pediatric procedure coding and bilateral rules.
Cataract extraction (66984/66982) carries a 90-day post-operative global package. Post-op visits are bundled — billing them separately, or missing modifier rules during the global, is the largest source of ophthalmology denials.
The 90-day global package means one surgical payment covers the procedure and all routine post-operative care for 90 days. Each phase has distinct coding rules.
Biometry, IOL calculation, and pre-op exam billed separately — not part of the global. Premium IOL upgrades documented.
92014 · 76519Cataract extraction with IOL. Bilateral procedures use modifier 50 for 150% payment — applied per payer bilateral-indicator rules.
66984 · mod 50All routine post-op visits included in the global payment — no separate E/M billing. Unrelated visits use modifier 24.
mod 24 · 79Eye surgery billing is governed by global periods, bilateral rules, and J-code drug capture that general billing companies cannot navigate effectively.
Routine post-op visits billed separately during the 90-day cataract global — denied as bundled, or worse, flagged as compliance risk.
Bilateral procedures (cataract, SLT, YAG) billed without modifier 50, or applied where the bilateral indicator is 0 — losing or denying revenue.
Intravitreal anti-VEGF injections (67028) lose drug revenue when J-code dosing, waste (JW), and single-use-vial billing aren't captured.
YAG capsulotomy (66821) performed in the post-op global of the original cataract surgery denied without modifier 79 (unrelated procedure).
OCT (92134) and fundus photography (92250) denied for medical-necessity gaps or when bundled into an E/M without a separate indication.
Premium IOL upgrade fees and refractive procedures are patient-pay — weak documentation and consent processes lose collectible revenue.

Real results from ophthalmology practices that partnered with MedFactor for specialty revenue cycle management.
An ambulatory surgery center was billing bilateral cataract surgery without modifier 50 and missing the bilateral adjustment. MedFactor implemented payer-specific bilateral-indicator checks, recovering substantial undercharged revenue in eight months.
A high-volume retina practice was dropping anti-VEGF single-use-vial waste and under-dosing J-code units. MedFactor implemented JW waste documentation and per-dose capture, recovering revenue that had been silently lost per injection.
A glaucoma clinic was losing revenue on SLT laser trabeculoplasty through bundling errors and missing global-period modifiers. MedFactor implemented modifier 50 and global-period protocols that protected laser procedure revenue.
No matter where your ophthalmology practice or surgery center operates, our team understands the payer landscape and regulatory requirements in your region.
Common questions from eye practices considering MedFactor's specialty RCM services.
Cataract extraction with IOL (66984/66982) carries a 90-day post-operative global package. The single surgical payment covers the procedure and all routine post-operative care for 90 days — routine post-op visits cannot be billed separately. Pre-operative workup and biometry are billed outside the global. During the global, an unrelated E/M visit uses modifier 24, and an unrelated procedure (like YAG capsulotomy) uses modifier 79. We track the global period for every cataract case so bundled visits aren't billed separately and legitimately unrelated services are captured with the correct modifier.
Modifier 50 is appended when a procedure with a bilateral indicator of 1 is performed on both eyes during the same session — common for cataract surgery (66984), YAG capsulotomy (66821), and SLT trabeculoplasty (65855). Most payers pay 150% of the fee schedule for a bilateral procedure. We verify each payer's bilateral indicator before applying modifier 50, because applying it where the indicator is 0 causes denials, and omitting it where allowed loses the bilateral adjustment. We also handle payer-specific submission rules (some want one line with modifier 50; others want two units).
Anti-VEGF injections (aflibercept/Eylea, ranibizumab/Lucentis, bevacizumab/Avastin) are billed with the procedure code 67028 (intravitreal injection) plus the drug's J-code billed per dosing unit — for example J0178 for aflibercept per 1 mg. When a single-use vial isn't fully used, the wasted drug is reported with the JW modifier. We capture the exact administered dose, document waste, and bill the administration separately from the drug — recovering drug and administration revenue general billers routinely miss.
YAG posterior capsulotomy (66821) treats posterior capsular opacity that can develop after cataract surgery. When performed during the 90-day post-op global of the original cataract surgery on the same eye, it's denied as bundled unless it's genuinely unrelated — which capsular opacity typically isn't until well after the global. Most YAG capsulotomies are performed months or years later, outside the global, and bill normally. When a YAG does fall in a global period for an unrelated reason, modifier 79 (unrelated procedure during the post-op global) is required. We track global dates so YAG is billed correctly.
Selective laser trabeculoplasty (SLT) is billed with CPT 65855 (laser trabeculoplasty). When performed bilaterally on the same day, modifier 50 applies where the payer bilateral indicator allows. SLT has a post-operative global period (typically 90 days), so follow-up visits within that global are bundled into the procedure payment. We confirm the laser session indication, apply the bilateral modifier per payer rules, and track the global so subsequent glaucoma visits are billed correctly — either bundled or with modifier 24 when unrelated.
OCT (92134) and fundus photography (92250) are diagnostic imaging tests that require their own medical-necessity indication — they are not bundled into an ophthalmology E/M (92014/92004) when ordered for a separate diagnostic reason. Denials happen when the indication isn't documented, when the test is performed without a supporting diagnosis, or when bilateral documentation is incomplete. We verify the supporting ICD-10 (such as H35 for retinal disease) is linked to the imaging order and document laterality so OCT and fundus photography are paid on first submission.
MedFactor applies the same code-level precision across the full practice spectrum. See how we bill these related specialties.
CPT®, ICD-10, HCPCS, and modifier codes referenced on this page reflect the current code sets and are subject to annual updates — always verify against the current-year fee schedule before submission. KPIs and case-study figures shown are representative benchmarks, not guarantees of individual practice results.
Your ophthalmology practice deserves billing partners who know the 90-day cataract global, modifier 50 bilateral rules, and anti-VEGF J-code capture — and code every claim correctly. Let MedFactor show you what specialty RCM can do.
